An efficient identity-based signature scheme with provable security

Many identity-based digital signature schemes are proved secure in the random oracle model. However, the application of the random oracle may lead to security risks. The used hash function is specific and the response result of the query is not always random, hence it may cause the insecurity of the scheme. To solve the above issues, this paper presents an efficient identity-based signature scheme which is proved secure under the standard model. The security of the proposed scheme is reduced to the well-known computational Diffie–Hellman (CDH) assumption. Furthermore, compared with the related identity-based signature schemes, the scheme proposed in this paper has great advantages in the computation cost of signing and verification.

A Privacy protection scheme for carpooling service using fog computing

As the traffic environment becomes more and more crowded, an increasing number of people are willing to carpool. Carpooling services provide convenience for drivers and passengers to share their journeys. But carpooling requests are uploaded to cloud server for processing and analysis in most existing schemes, resulting in communication delays and leakage of user privacy. To solve this problem, we propose a privacy protection scheme for carpooling service using fog computing. First, identity-based digital signature technology is used to achieve anonymous authentication. Second, location tags, bloom filters and fuzzy extractors are utilized to match passengers and drivers without disclosing the users’ location; Consortium blockchain technology is adopted to store carpooling records. Finally, security analysis and experiments results show that our scheme offers privacy preservation and security, while maintaining low computational cost.

Trust Management Scheme Based on Hybrid Cryptography for Secure Communications in VANETs

Vehicular Ad hoc Networks (VANETs) are used to improve traffic management and reduce the number of road accidents by providing safety applications. However, VANETs are susceptible to a number of security attacks from malicious entities. To secure the network against these attacks, most of the researchers have proposed various security schemes based on cryptography and trust management. While both cryptography and trust management are effective to some extent, each scheme has some flaw to fully secure the network. In this paper, we propose a trust management scheme based on hybrid cryptography (TMHC) to secure VANET to a larger extent. As authentication is an integral part of trust establishment and secure communications between vehicles, the proposed TMHC integrates hybrid cryptography based authentication for efficient and robust trust management scheme. The hybrid cryptography includes, asymmetric identity-based (ID-based) digital signature and symmetric hash message authentication code (HMAC). The trusted road-side unit (RSU) evaluates trust-value, whereas, agent trusted authority (ATA) computes trust-value of vehicle based on its reward-points. The results are gained with extensive simulations to validate the proposed scheme. The results show that the proposed scheme meets security requirements and performs effectively. The communication overhead, computation overhead, storage overhead, and end-to-end delay of the proposed scheme were improved by 6% to 15%, 9% to 23%, 7% to 19%, and 4% to 15.85%, respectively, as compared to existing schemes.

An energy efficient authentication scheme based on hierarchical IBDS and EIBDS in grid-based wireless sensor networks

Wireless sensor network is a peculiar kind of ad hoc network, consists of hundreds of tiny, resource constrained as sensor nodes. Clustering is a demanding task in such environment mainly due to the unique constraints such as energy efficiency and dynamic topology. In this paper, a novel energy efficient cluster-based routing algorithm is proposed on which hierarchical identity-based digital signature (IBDS) and enhanced-identity-based digital signature (EIBDS) scheme is concerning in grid-based wireless sensor networks. Firstly we form clusters using multi-parameters-based type-2 fuzzy logic algorithm. This paper proposes an improved ant colony optimisation algorithm, which optimises the energy consumption on data transfer in a WSN. Each node in a sensor network is authenticated using elliptic curve cryptography (ECC). After a set of simulation tests on NS-3 simulator, our proposed work achieves good performance for various metrics.

Enhancing Performance Of WSN By Utilizing Secure Qos Based Explicit Routing

Wireless sensor networks (WSN) are infrastructure less and self-configured a wireless network that allows monitoring the physical conditions of an environment. Many researchers focus on enhancing the performance of WSN in order to provide effective delivery of data on the network, but still results in lower quality of services like energy consumption, delay and routing. We tackle this problem by introducing a new routing algorithm, QoS-based explicit routing algorithm which helps in transmitting the data from source node to destination node on WSN. We also involve clustering process in WSN based on genetic algorithm and particle swarm optimisation (GA and PSO) algorithm. We proposed identity-based digital signature (IBDS) and enhanced identity-based digital signature (EIBDS) that involves reduction of computation overhead and also increasing resilience on the WSN. We also use advanced encryption standard (AES), for ensuring the security between nodes and avoid hacking of data by other intruders.

Efficient authentication scheme for vehicular ad-hoc networks with batch verification using bilinear pairings

The potential for vehicular ad hoc networks (VANETs) in improving traffic, enhancing road safety and reducing traffic accidents has attracted attention from academia, industry, and governments. To ensure secure communication in VANETs, a number of authentication schemes, including those with batch verification, were proposed in recent years. However, studies have demonstrated that most of the existing schemes suffer from bad performance or weak security. To address those problems, we construct a new identity-based digital signature (IBDS) scheme using bilinear pairings. The IBDS scheme is then used to construct a new identity-based conditional privacy-preserving authentication (IBCPPA) scheme for VANETs without the need for a map-to-point hash function or double secret keys. Using simulations, we demonstrate that our provably-secure IBCPPA scheme not only achieves better performance than related schemes, but also overcomes the inefficiency problem of the double secret keys in related schemes (i.e., the system does have to manage two secret keys to provide security).

Identity-based undetachable digital signature for mobile agents in electronic commerce

To enable mobile agents signing securely on potentially malicious hosts in electronic commerce and other applications, we proposed the definition and security notion of identity-based undetachable digital signature schemes. More importantly, we proposed a concrete identity-based undetachable digital signature scheme with provable security. In the scheme, mobile agents need not carry the private key when they generate digital signatures on behalf of the original signer, so the private key will not be compromised. The encrypted function is combined with the original signer’s requirement, so misuse of the signing algorithm can be prevented. Moreover, because the scheme is identity-based, verification of the signatures generated by mobile agents does not require either verification of the entire certificate path or communication with the certification authority. Therefore, compared with existing undetachable signature schemes, the cost of verification is reduced and even the dependence on a stable network connection is weakened.

Two New Secure and Efficient DataTransmission Protocols SET-IBS and SETIBOOSfor WSN

Recent advances have given rise to popularity and successes of wireless sensor networks. Secure transmission of data is found to be very critical in WSNs (Wireless Sensor Networks). The technique of clustering is found to be very efficient and practical in WSNs. This technique is useful to increase the performance of the system in WSNs. This technique is very useful for Cluster Based Wireless Sensor Networks. Recent studies proposed two new Secure and Efficient Data Transmission Protocols for wireless sensor networks. The two protocols are named SET-IBS and SET-IBOOS. They use Identity Based Digital Signature (IBS) and Identity Based Online/Offline Digital Signatures (IBOOS) respectively. Compared to the traditional protocols the proposed protocols provide more security. Generally, key exchange is a big overhead for any secure data transmission protocols. This is removed in the proposed system by introducing Base Station. SET-IBOOS Scheme reduces the computational overhead

Secure and Efficient Collaborative Load Balancing for Cluster-based MANETs

Mobile ad hoc networks (MANETs) are becoming increasingly common, and typical network loads considered for MANETs are increasing as applications evolve. Coordinated channel access protocols have been shown to be well suited for highly loaded MANETs under uniform load distributions. However, these protocols are in general not as well suited for non-uniform load distributions as uncoordinated channel access protocols due to the lack of ondemand dynamic channel allocation mechanisms that exist in infrastructure based coordinated protocols. In this paper, we present a lightweight dynamic channel allocation mechanism and a cooperative load balancing strategy that are applicable to cluster based MANETs to address this problem. We present protocols that utilize these mechanisms to improve performance in terms of throughput, energy consumption and inter-packet delay variation.

Strongly Secure Certificateless Signature Scheme Supporting Batch Verification

We propose a strongly secure certificateless signature scheme supporting batch verification, which makes it possible for a verifier to verify a set of signatures more efficiently than verifying them one by one. In an identity-based digital signature scheme, private key generator (PKG) knows each user's signing key, so it can generate a signature which is indistinguishable from the signature generated by the user. This is a serious problem because the property of signature nonrepudiation will not be achieved. In our proposed scheme, it is impossible for PKG to produce a signature which is indistinguishable from any signature produced by a user. Compared with existing signature schemes with batch verification, although our proposed scheme is not the most efficient one, it achieves Girault's level-3 security, while the others have Girault's level-1 or level-2 security only. We also formally prove that the proposed scheme is unforgeable and satisfies Girault's level-3 security based on hard problems.

Creation of identity-based digital signature schemes from bilinear maps

Bilinear schemes of identity-based digital signatures are proposed as analogs for the algorithms defined by the Ukrainian (4145-2002), German (EC-GDSA), and Korean (EC-KCDSA) State Standards, and threshold schemes based on such bilinear schemes are constructed. These schemes may be alternatives to public key infrastructures based on certificates, especially in the case when an effective efficient key management is required at a rather moderate security level.
