Multi-receiver Signcryption Scheme Research Articles

Multi-message multi-receiver signcryption scheme based on blockchain.

In conventional message communication systems, the practice of multi-message multi-receiver signcryption communication encounters several challenges, including the vulnerability to Key Generation Center (KGC) attacks, privacy breaches and excessive communication data volume. The KGC necessitates a secure channel to transmit partial private keys, thereby rendering the security of these partial private keys reliant on the integrity of the interaction channel. This dependence introduces concerns regarding the confidentiality of the private keys. Our proposal advocates for the substitution of the KGC in traditional certificateless schemes with blockchain and smart contract technology. Parameters are publicly disclosed on the blockchain, leveraging its tamper-proof property to ensure security. Furthermore, this scheme introduces conventional encryption techniques to achieve user identity privacy in the absence of a secure channel, effectively resolving the issue of user identity disclosure inherent in blockchain-based schemes and enhancing communication privacy. Moreover, users utilize smart contract algorithms to generate a portion of the encrypted private key, thereby minimizing the possibility of third-party attacks. In this paper, the scheme exhibits resilience against various attacks, including KGC leakage attacks, internal privilege attacks, replay attacks, distributed denial of service attacks and Man-in-the-Middle (MITM) attacks. Additionally, it possesses desirable security attributes such as key escrow security and non-repudiation. The proposed scheme has been theoretically and experimentally analyzed under the random oracle model, based on the computational Diffie-Hellman problem and the discrete logarithm problem. It has been proven to possess confidentiality and unforgeability. Compared with similar schemes, our scheme has lower computational cost and shorter ciphertext length. It has obvious advantages in communication and time overhead.

Completely Anonymous Certificateless Multi-Receiver Signcryption Scheme with Sender Traceability

Certificateless multi-receiver signcryption scheme provides an efficient solution for one-to-many communication applications and avoids the key escrow problem in the existing identity-based multi-receiver signcryption schemes. Many certificateless multi-receiver signcryption schemes have been proposed with various secure properties, such as receiver anonymity and sender anonymity. However, among the existing certificateless multi-receiver signcryption schemes with sender anonymity, there is no scheme considers the sender tracing functionality. Sender anonymity is vulnerable and contradicts with non-repudiation. The anonymous sender may disavow the illegal message he has sent, which compromises the non-repudiation, so there is a high desirability to provide a sender tracing functionality which can be execute under certain conditions to balance the sender anonymity and non-repudiation. Motivated by these concerns, a new certificateless multi-receiver signcryption scheme is proposed, which achieves completely anonymity and provides the sender tracing functionality. In the proposed scheme, the key generation center can cooperate with any authorized receiver to trace the anonymous sender, but neither of them can do it alone. In this case, sender anonymity and non-repudiation reach a certain degree of balance.

Light-weight Security Protocol in IoT with Less Computational Cost

Firewalls are the emerging technology to secure the internal network resources from outsider attacks. On the other hand, Authentication, integrity, and confidentiality are the main security challenges for firewalls. To achieve these security challenges, recently, two multicast signcryption schemes have been contributed to the literature. These two Signcryption suffer from two main flaws: computational cost and our head communication. Keeping in view these two flaws, we designed a new multi-receiver signcryption scheme that is lightweight. A lightweight and well-secured protocol is presented for smart-IOT-based homes that are proven to be secured against impersonation, replay, and exposed session key attacks. The Proposed technique is experimented with using the AVISPA tool to ensure that the various attacks do not crack it. The efficiency and security of the proposed scheme are based on a hyperelliptic curve cryptosystem. The hyperelliptic curve cryptography is the subtype of an elliptic curve cryptosystem, and the key size is low from the elliptic curve. Our scheme provides all the security requirements provided by the existing multi-receiver signcryption schemes with low computational and communication costs.

Multi-receiver signcryption scheme with multiple key generation centers through public channel in edge computing

The emerging edge computing technology for the Internet of Things has been playing an important role in our daily life. It is promising to utilize a multi-receiver signcryption scheme to protect the transmission data when an edge device broadcasts its sensing data to many different end devices at a time. There are several things to consider when we design a signcryption scheme. First existing schemes need to maintain a secure channel to generate the user private key, which may increase economic costs. Second the system private key of those schemes is kept secret by a single key generation center (KGC), and the single point of failure of KGC may compromise the whole system. For this, we propose a multi-receiver multi-message signcryption scheme without the secure channel. Firstly the scheme allows KGC to send secrets through the public channel, which reduces maintenance costs. Secondly, to eliminate the single point of failure, the scheme utilizes multiple KGCs to manage the system private key, and updates the secret of each KGC periodically to resist advanced persistent threat attacks. We demonstrate that the proposed scheme can achieve expected security properties. Performance analysis shows that it is with shorter ciphertext length and higher efficiency.

Efficient and provably secure multi-receiver signcryption scheme using implicit certificate in edge computing

Edge computing is an emerging computing paradigm, which extends the functions of cloud center to the edge of the networks, and brings great convenience to solving problems of delay and bandwidth in the traditional cloud computing paradigm. In edge computing architecture, one-to-many communication is a important communication mode that supports the edge nodes to send one message to multiple terminal devices in one broadcast report. To build a secure one-to-many communication, several multi-receiver signcryption (MRSC) schemes have been brought forward to ensure the security of broadcast messages. However, the existing MRSC schemes need the heavy computation and communication cost, and is not suitable for IoT terminal devices with limited resources. Besides, most of the existing MRSC schemes are vulnerable to the security and privacy leakage, and fail in achieving the decryption fairness. To solve these problems, based on the implicit certificate (IC) cryptosystem and polynomial interpolation evaluation, this paper proposes an provably secure multi-receiver IC-based signcryption (MRICSC) scheme for one-to-many communication in edge computing. The security analysis evidences the proposed MRICSC scheme can ensure the security. With the experimental results indicating that the proposed MRICSC scheme achieves the better performance than existing schemes.

An Efficient and Secure Multimessage and Multireceiver Signcryption Scheme for Edge-Enabled Internet of Vehicles

The Internet of Vehicles (IoV) is considered an enhancement of existing vehicular ad-hoc networks, which helps connect mobile vehicles to the Internet of Things (IoT) with the support of 5G networks. To assure the quality-of-service demand by the users, the edge computing paradigm of 5G networks can be incorporated in the IoV environment for supporting compute-intensive applications. The basic safety messages are typically transmitted using a multicast pattern in the IoV-enabled edge computing paradigm. The use of the multicast channel may accelerate the communication process; however, it is prone to various attacks due to the open nature of wireless networks. This article proposes a multimessage and multireceiver signcryption scheme for the multicast channel in a certificateless setting to solve the key escrow problem. The security of the partial private key is dependent on the secure channel, which increases the complexities of the system. Therefore, in the proposed scheme, we introduce a new idea that does not require a secure channel. The key generation center only sends the pseudo partial private key of the users on a public channel. Furthermore, the proposed scheme is based on hyper-elliptic curve cryptography (HECC), which has much smaller key sizes as compared to elliptic curve cryptography (ECC). The security proofs and performance comparison for our scheme are carried out. The findings show that the proposed scheme provides high security while using less computational and communication costs.

A Multi-Message Multi-Receiver Signcryption Scheme with Edge Computing for Secure and Reliable Wireless Internet of Medical Things Communications

Thanks to recent advancements in biomedical sensors, wireless networking technologies, and information networks, traditional healthcare methods are evolving into a new healthcare infrastructure known as the Internet of Medical Things (IoMT). It enables patients in remote areas to obtain preventative or proactive healthcare services at a cheaper cost through the ease of time-independent interaction. Despite the many benefits of IoMT, the ubiquitously linked devices offer significant security and privacy concerns for patient data. In the literature, several multi-message and multi-receiver signcryption schemes have been proposed that use traditional public-key cryptography, identity-based cryptography, or certificateless cryptography methods to securely transfer patient health-related data from a variety of biomedical sensors to healthcare professionals. However, certificate management, key escrow, and key distribution are all complications with these methods. Furthermore, in terms of IoMT performance and privacy requirements, they are impractical. This article aims to include edge computing into an IoMT with secure deployment employing a multi-message and multi-receiver signcryption scheme to address these issues. In the proposed method, certificate-based signcryption and hyperelliptic curve cryptography (HECC) have been coupled for excellent performance and security. The cost study confirms that the proposed scheme is better than the existing schemes in terms of computational and communication costs.

Anonymous and Efficient Certificateless Multirecipient Signcryption Scheme for Ecological Data Sharing

Air pollution, water pollution, soil erosion, land desertification, and other environmental issues are becoming more and more serious. And ecological security has become a key issue for the sustainable development of the world, so research on ecology has received more and more attention. At present, ecological data is collected and stored separately by various departments or agencies. In order to conduct better research, various institutions or individuals begin to share their own data. However, data sharing between different organizations is affected by many factors, especially data security issues. At the moment, there is no scheme that has been commonly recognized to solve the problem of ecological data sharing. To provide a secure data sharing way for ecological research, a certificateless multireceiver signcryption scheme is proposed. In this paper, the proposed scheme can solve the key escrow problem, and it can improve efficiency on the basis of ensuring security by adopting elliptic curve cryptography (ECC). A rigorous security analysis proves that the scheme can resist various security attacks and ensure privacy protection based on a random oracle model. Performance analysis also shows that this scheme has the advantage of computational overhead compared to the same type of scheme. Therefore, the scheme is very suitable for the safe sharing of ecological data.

Efficient Anonymous Certificate-Based Multi- Message and Multi-Receiver Signcryption Scheme for Healthcare Internet of Things

Healthcare Internet of Things (IoT) is an emerging paradigm, which can provide comprehensive and different types of health services and enable various types of medical sensors to monitor patient's health conditions. In the healthcare IoT, patient is deployed with a variety of medical sensors, which continuously monitors and collects patient's sensitive health data that needs specially protection for preventing privacy leakage. To safely send multiple different health data monitored by multiple different medical sensors to multiple corresponding healthcare professionals in one data report, several multi-message and multi-receiver signcryption schemes have been introduced by employing the traditional public key cryptography, identity-based cryptography or certificateless cryptography. However, these schemes suffer from the certificate management, key escrow and key distribution problem. Besides, due to the resource-constraint property of medical sensors, they are unsuitable for healthcare IoT in terms of both performance and privacy requirements. To solve these issues, this paper introduces an efficient anonymous certificate-based multi-message and multi-receiver signcryption scheme for healthcare IoT, where the certificate-based cryptography and elliptic curve cryptography are combined to simplify the certificate management problem, eliminate the key escrow problem, solve the key distribution problem and ensure the privacy-preserving. Furthermore, the security analysis suggests that the proposed scheme is able to achieve the confidentiality, unforgeability, receiver anonymity, sender anonymity and decryption fairness; the performance evaluation indicates that the proposed scheme brings to the lower computation cost and communication cost in comparison to the existing schemes.

Secure and Blockchain-Based Emergency Driven Message Protocol for 5G Enabled Vehicular Edge Computing.

Basic safety message (BSM) are messages that contain core elements of a vehicle such as vehicle’s size, position, speed, acceleration and others. BSM are lightweight messages that can be regularly broadcast by the vehicles to enable a variety of applications. On the other hand, event-driven message (EDM) are messages generated at the time of occurrence such as accidents or roads sliding and can contain much more heavy elements including pictures, audio or videos. Security, architecture and communication solutions for BSM use cases have been largely documented on in the literature contrary to EDM due to several concerns such as the variant size of EDM, the appropriate architecture along with latency, privacy and security. In this paper, we propose a secure and blockchain based EDM protocol for 5G enabled vehicular edge computing. To offer scalability and latency for the proposed scenario, we adopt a 5G cellular architecture due to its projected features compared to 4G tong-term evaluation (LTE) for vehicular communications. We consider edge computing to provide local processing of EDM that can improve the response time of public agencies (ambulances or rescue teams) that may intervene to the scene. We make use of lightweight multi-receiver signcryption scheme without pairing that offers low time consuming operations, security, privacy and access control. EDM records need to be kept into a distributed system which can guarantee reliability and auditability of EDM. To achieve this, we construct a private blockchain based on the edge nodes to store EDM records. The performance analysis of the proposed protocol confirms its efficiency.

Efficient and Provably Secure Multireceiver Signcryption Scheme for Multicast Communication in Edge Computing

With the popularity of edge computing, edge nodes are connected with the Internet of Things (IoT) devices to process and analyze IoT-created data, and feedback corresponding results to users, devices, or data centers. In the edge computing environment, multicast is a typical communication pattern to support data transmitting between edges and devices. It allows the sender to send messages to multiple receivers in one broadcast message. To construct a secure multicast channel, the primary issue is to ensure the privacy and credibility of the transmitted message in the open wireless communication. Then, another essential issue for multicast channels is receiver anonymity, i.e., only the sender knows the receivers’ identities. Also, efficiency and provable security are critical in scheme design. In this article, we design a certificateless multimessage and multireceiver signcryption (CLMMSC) scheme by using the elliptic curve cryptography. To facilitate lightweight deployment, we adapt the certificateless mechanism to reduce the system operation and maintenance costs. Then, through security proofs, we demonstrate that the proposed scheme can achieve the expected security properties. The performance analysis shows that the proposed scheme has lower communication costs than previous CLMMSC schemes.

Efficient and Anonymous Certificateless Multi-Message and Multi-Receiver Signcryption Scheme Based on ECC

As the further extension of the multi-receiver signcryption, the multi-message and multi-receiver signcryption allows a sender to simultaneously signcrypt different messages for different receivers in only one logic operation, which makes it more flexible than the traditional multi-receiver signcryption in which only the same and unique message can be sent to all authorized receivers. The existing multi-message and multi-receiver signcryption schemes are constructed based on either the identity-based cryptography or the public key infrastructure-based cryptography, and thus, they have to suffer from the key escrow problem inherent in the identity-based cryptography or the public key certificate management burden related with the public key infrastructure-based cryptography. Certificateless public key cryptography provides an idea to solve the key escrow problem and eliminate the public key certificate management burden and has been applied to many cryptographic algorithms. In this paper, to avoid the above problems in the existing multi-message and multi-receiver signcryption schemes, the concept of the certificateless public key cryptography was introduced into the designing of the multi-message and multi-receiver signcryption, and a certificateless multi-message and multi-receiver signcryption scheme was proposed. The proposed scheme is free from the key escrow problem and the public key certificate management burden because it is constructed based on the certificateless public key cryptography. Moreover, compared with the existing schemes, it is improved in efficiency because it does not use the bilinear pairing operations but utilizes the limited number of scalar point multiplication on elliptic curve cryptography operations. At the same time, the proposed scheme achieves receiver anonymity.

Anonymous Certificateless Multi-Receiver Signcryption Scheme Without Secure Channel

The certificateless multi-receiver signcryption scheme provides the sender with the ability to send the same message to multiple authorized receivers contemporaneously, and at the same time, it can avoid the key escrow problem in the existing identity-based multi-receiver signcryption schemes, which makes it to get great attention in the field of one-to-many communication. However, in the existing certificateless multi-receiver signcryption schemes, a secure channel is essential for their key extract algorithm, which brings some troubles in practical applications. On one hand, the security of the partial private key depends on the secure channel. Once the secure channel is broken by an attacker, the user’s partial private key may be leaked. On the other hand, maintaining the secure channel increases the economic cost and implementation complexity of the application systems. Motivated by these concerns, we propose a new anonymous certificateless multi-receiver signcryption scheme, in which the key generation center only utilizes a public channel to send the pseudo partial private key to the user during the key extract algorithm, and the designated user can work out the real partial private key from the pseudo partial private key while others cannot. The avoidance of the secure channel improves the security of the proposed scheme and makes the communication system much lighter.

An Efficient Multi-Message and Multi-Receiver Signcryption Scheme for Heterogeneous Smart Mobile IoT

The Internet of Things (IoT) is developing towards smart and mobile Internet of Things (SM-IoT), which has made great progress. Due to the inherent heterogeneity, distribution, intensive communication, and resource constraints of SM-IoT, efficient security and privacy communication protocols become a particularly critical challenge. Signcryption has received considerable attention. Various signcryption schemes have been proposed to solve secure communication. However, most of them are low in efficiency, without the consideration of characteristics of the SM-IoT. In this paper, we propose a signcryption scheme to achieve efficient secure multi-message and multi-receiver communication for the heterogeneous and distributed SM-IoT. We develop Identity-based Cryptography (IBC) and Certificateless Cryptography (CLC) to solve the certificate management problem. Our scheme no longer needs wireless secure channel during key generation phase of traditional CLC system, which improves the applicability of our scheme in wireless SM-IoT environment. There is no expensive operations, such as bilinear pairing, in our scheme. In addition, our scheme out sources part of the verification overhead from the SM-IoT users to the gateway without revealing user privacy. The performance evaluation shows that the computation efficiency in both sender and receiver side is improved in our scheme.

Efficient Anonymous Certificateless Multi-Receiver Signcryption Scheme Without Bilinear Pairings

Certificateless multi-receiver encryption/signcryption (CLME/CLMS) has become a research hotspot in the field of information security. Almost all of the existing CLME/CLMS schemes are constructed based on the bilinear pairing computation, a time-consuming operation, which makes their computational efficiency relatively low. Although there are some CLME schemes constructed on scalar point multiplications on elliptic curve cryptography (ECC) instead of the bilinear pairing computation, too many scalar point multiplications involved still lead to the low computational efficiency. Therefore, there is still room for the CLME/CLMS schemes in efficiency. Motivated by these concerns, an efficient anonymous certificateless multi-receiver signcryption scheme is proposed with its security proved under the random oracle model. The proposed scheme is improved largely in computational efficiency by the idea that it is designed based on scalar point multiplications on ECC instead of the bilinear pairing and the number of scalar point multiplications on ECC is reduced as small as possible.

Multi-message and multi-receiver heterogeneous signcryption scheme for ad-hoc networks

ABSTRACTSecurity is a significant issue for ad-hoc networks. Heterogeneous signcryption schemes proposed in recent years satisfy privacy and authentication of messages and reduce cost of computation and communication in a logical step. In this article, we present a new efficient heterogeneous signcryption scheme that shifts between the public key infrastructure (PKI) and the identity-based cryptosystem (IBC). The proposed scheme is suitable for broadcast communication conditions in which senders can signcrypt multiple messages for multiple receivers simultaneously in the ad-hoc networks. This scheme is proved to satisfy confidentiality and unforgeability on the basis of the assumptions of bilinear Diffie-Hellman problem (BDHP), q-Diffie-Hellman inversion problem (q-DHIP), q-bilinear Diffie-Hellman inversion problem (q-BDHIP), and computational Diffie-Hellman problem (CDHP) in the random oracle model. We discuss the efficiency of our scheme theoretically. In the efficiency analysis phase, we show that our scheme is practical and efficient. In the performance analysis phase, we present additional tests, data, and explanations to prove that our scheme can be applied in ad-hoc networks. Finally, we apply our scheme to a simulated ad-hoc network.
