A Data Encryption and Approximate Recovery Strategy Based on Double Random Sorting and CGAN

The measurement data in the power system may be attacked and tampered during the transmission. For this problem, a data encryption and approximate recovery strategy based on double random sorting and CGAN is proposed. The double random sorting encryption algorithm is proposed based on the form of measurement data in plaintext. The randomness of pseudo-random number, random sequence and random sequence insertion will ensure the uncertainty of data block number, sorting order and insertion location of random sequence, which will definitely improve the security of measurement data. Besides, an approximate recovery strategy used to approximately recovery abnormal samples is proposed on the base of CGAN, which can ensure the accuracy of decryption. Finally, the feasibility, and effectiveness of the proposed method are analyzed on wind power and photovoltaic power historical dataset.

Optimal Elliptic Curve Cryptography-Based Effective Approach for Secure Data Storage in Clouds

With the rapid development of cloud advancement, a data security challenge has emerged. In this paper, a technique based on elliptical cryptography and cuckoo search algorithm is proposed. With this technique, data owners securely store their data files in the cloud server. Initially the user sends a file storage request to store a file in a cloud server provider (CSP). The input file is checked whether it is sensitive or non-sensitive by the user. If the file is sensitive, then it would be split and stored in different virtual machines (VMs), and if the file is non-sensitive, then it would be assigned in a single VM. This approach was used for the first time as per the survey. To add further security, the sensitive data retrieval needs an encryption process that is supported by the proposed algorithm. If the data owner stores the sensitive data to cloud server, the data owner's document is encrypted by the double encryption technique. Here RSA and optimal elliptic curve cryptography (OECC) algorithm is used to encrypt the document with high security. The authors have used cuckoo search algorithm to identify the optimal key in ECC. This paper has proposed a novel cryptography approach for delivering mass distributed storage by which user's original data cannot be directly reached by cloud operators. Hence, this research has proved that the proposed work will give better securable data storage solving the security issues.

Research on E-commerce Payment Security and Privacy Protection Based on Improved B2C Model

The popularity of Internet and mobile terminalspromotes the development of e-commerce. However, e-commercewhich is not necessary to face to face poses a major challenge to thepayment security and privacy protection of consumers. This paperbriefly introduces the traditional business to customer (B2C)e-commerce model. A third-party privacy server was introduced toprovide a double encryption algorithm for the model, and then thetraditional and improved B2C models were simulated to verify theperformance of the two models in the confidentiality of the transactioninformation and the security of the transaction informationtransmission process. The results showed that the intruder could notdirectly obtain the sensitive privacy information such as paymentinformation and order information of consumers even if he invaded thedatabase of the online store when the improved B2C model was used;after the transaction information was intercepted and decrypted underthe two B2C models, the decryption integrity decreased with theincrease of the transaction information quantity, while under the sametransaction information quantity, the decryption integrity of theimproved B2C model was lower

Multi-image holographic encryption based on phase recovery algorithm and ghost imaging

There is a method that presents for securing much information at the same time, which need not be restricted to a single image data. Based on ghost imaging, this paper proposes a new encryption algorithm: multi-image holographic encryption based on phase recovery algorithm and ghost imaging (PRA-GI). In the encryption process, first, multiple images are combined into one phase hologram image by phase holographic recovery algorithm. Second, the combined image is encrypted by ghost imaging to obtain ciphertext. During the decryption, each receiver can get the same phase hologram image reconstructed by the public key. Finally, each receiver uses the unique assisted private key to get corresponding information. By numerical simulation, it is found that this algorithm can effectively improve the encryption capacity. Experimental results and objective indicators verify the feasibility of this algorithm. At the same time, PRA-GI is suitable for enterprises and governments. For example, the leader license different assisted private keys and the primary public key to different employees according to different permissions. This algorithm implements double encryption, which ensures the security of information and solves crosstalk problems among images.

A Novel Optimal Routing Protocol for Wireless Ad hoc Network with the aid of Double Encryption Mechanism

Ad hoc network paved way to various researches and application due to its wide acceptance over wired network. The advance has also led to various drawbacks or problems that can result in unauthorized usage of data or in data loss. So secured data transfer has become an important requirement in any Ad hoc network. Various issues exist in Ad hoc network while data transmission and hence it has become a major requirement to develop an efficient routing protocol that can transmit the data securely over the network.

Also, we design an efficient optimal routing protocol that makes the transmission secured by reducing various attacks that occur in the network. It provides the security for image transmission over internet effectively. This technique also can be extended in multimedia security over the internet. The network parameters will be approximately judged in order to demonstrate the performance of the scheme we develop.

A Hybrid Method for Secure Communication and Performance Analysis in VANET.

Vehicular Ad-hoc network a subclass of Mobile Ad-hoc network with various features providing Vehicle-to-Vehicle communication, Vehicle-to-RSU communication, Vehicle-to-Trusted Authority Communication. VANET is gaining higher attention now days both in industry and academic area and has become a trending research topic for research but still a lot of improvements is required in this area. Security of data is one of the major challenge in VANET. Encryption of data with the help of various encryption algorithms came up as solution for securing communication in VANET. But existing encryption algorithms used to secure VANET’s are complex due to which data are not delivered on time and face a lot of problems like privacy of data ,non-repudiation and cost (i.e. communication cost, computational cost).In our proposed scheme we use a hybrid approach, which contain ECC algorithm( asymmetric algorithm).ECC algorithm is used for encryption of personal details (i.e. Speed, location, device address) and AES algorithm (symmetric algorithm ) is used for encryption for safety messages along with output of ECC algorithm. The objective of this hybrid approach is to perform double encryption on personal details for more privacy of personal data (using ECC and AES algorithm) and single encryption on safety messages (using AES algorithm) so safety messages are delivered on time and without any delay.

Efficient Photomodulation of Visible Eu(III) and Invisible Yb(III) Luminescences using DTE Photochromic Ligands for Optical Encryption

AbstractThis work describes a class of complex combining three dithienylethene units and a lanthanide ion used as an optical system displaying a double encryption method: i) a colorful code, drawn and erased under UV and visible irradiations respectively, due to coloration and discoloration of the photochromic entities, and ii) a concomitant gradual disappearance and progressive restoration of the associated lanthanide ion luminescence triggered with the same stimuli. The innovation of the system stems from the emission color tunability, i.e., with either a lanthanide ion emitting only in the visible range (Eu3+) or with another lanthanide ion emitting only in the near infrared (NIR) range (Yb3+), therefore observable, or not, to the naked eye. This system is the very first one to achieve efficient repeatable modulation of pure NIR luminescence on photochemical command. Furthermore, it is proven to be highly efficient when embedded in a PDMS polymer opening real opportunities for practical applications as anti‐counterfeiting.

SYNCHRONIZATION BETWEEN INTEGER AND FRACTIONAL ORDER DELAY NEURAL NETWORKS SYSTEM

The purpose is to present a method for synchronizing a recurrent neural networks system between integer and fractional-order order delay by active sliding mode control . The Active Sliding Mode Control (ASMC) scheme is used to solve the synchronization problem between the integer-order delayed recurrent neural networks system via active sliding mode control (IoDRNNASM) systems and the fractional-order delay recurrent neural networks system via active sliding mode control (FoDRNNASM) system based on the Lyapunov direct fractional method (LDFM). To explore the behavior of the IoDRNNASM systems and the FoDRNNASM systems, we performed the technique of numerical simulations using MATLAB software to prove the feasibility and strength of the archived outcomes. This concept can also be enhanced with the implementation of double encryption using RSA encryption to secure communication. Because we expected in the future that this enhanced concept will strengthen and increase the network security capabilities that will provide powerful protection in secure communications.

Research on order-preserving encryption scheme based on CryptDB

With the rapid development of cloud computing technology, cloud database, as an important part of cloud computing services, has gradually become necessary for daily work of enterprises or individuals. However, entrusting data to third-party managing can lead to security issues such as data leakage, and users cannot guarantee data security. To this end, this paper is based on the CryptDB, an open source database encryption proxy system designed by MIT, in this thesis we propose an improvement scheme for the shortcomings of the original CryptDB system. Specific contents including: By studying the CryptDB system, we find that the system is lack of scalability for different databases and does not involve the management of system keys. For the inefficiency of the mutable Order-Preserving Encryption (mOPE) in CryptDB system, we propose an improved additive Order-Revealing Encryption (aORE) scheme by combining the Practical Order-Revealing Encryption (P-ORE) and mOPE. The scheme is based on pseudorandom function and double encryption. Compared with mOPE, it can improve the execution efficiency of the Order-Preserving scheme at the expense of security.

Intelligent Metallurgical Data Statistics Software Encryption based on Real-Time Double Encryption Algorithm

One-way encryption in the traditional encryption system of smart phone makes mobile phone easy to be attacked by the outside world, resulting in poor security performance. In order to solve this problem, a design of security encryption system for smart phone software based on real-time dual encryption is proposed. The method of resource verification integrity is designed, and a group of congruence numbers is added to the software’s sensing resources to perform module operations and homomorphic encryption operations to generate encrypted data. In the reversible hiding process of dual encryption for real-time mobile phone information, chaotic sequence is used to realize the global scrambling of mobile phone information location. According to another new set of chaotic sequence, the 0bit and 1bit are scrambled in the information value of mobile phones. Chaos mapping is used to generate chaotic sequences and are associated with the mobile phone information to ensure that the dual encryption of mobile information can resist the selection of message attack. The experimental results show that the maximum confidentiality of the system can reach 96%, which is of practical value.

Invisible Inks for Secrecy and Anticounterfeiting: From Single to Double-encryption by Hydrochromic Molecules.

Secret information recorded by traditional single-encrypted invisible inks is easily cracked because the inks can switch only between "NONE" and "TRUTH". Developing double-encrypted systems makes the information reversibly switchable between "FALSE" and "TRUTH", which is helpful to ensure the safety of the secret information during transport. Here, we prepared heat-developed invisible inks by hydrochromic molecules donor-acceptor Stenhouse adducts (DASAs) and oxazolidines (OXs) and promoted the invisible inks from single to double encryption. DASAs coordinate with water molecules and form stable colorless cyclic DASA·xH2O molecules, which lose coordinated water molecules after heating and switch to colored linear DASAs. In contrast, OXs are colored with water and are colorless after heating. Single-encrypted secrecy was realized by DASA invisible inks. The information is invisible under the encrypted state and becomes bright purple after heating. Vapor treating re-encrypted the information in ∼5 min. Furthermore, the single-encryption was promoted to double-encryption by a DASA/OX invisible inks system. Heating and vapor treating switch the information between the "FALSE" and "TRUTH" reversibly. The DASA/OX invisible ink system is applied for secrecy of texts, graphic images, and quick response (QR) codes.

Asymmetric image optical encryption under spatially incoherent illumination

In this paper new method of asymmetric optical encryption is presented. It is based on the double encryption using spatially incoherent illumination: to obtain a ciphertext a plaintext is encoded twice, first time by sender, second time—by recipient. This way no exchange of encryption keys is required. Two variants of this method were analyzed: one in which both encryption procedures are implemented optically and another one in which the first operation is done optically and the second one—numerically. Both variants were numerically simulated and the latter one was implemented optically. Results of numerical and optical experiments demonstrate high quality of decrypted images (decoding error 0.19), thus confirming usability of proposed method.

Data storage security for the Internet of Things

In the present era, secure data storage for any Internet of Things (IoT) platform is plagued by poor performance of secure read and write operations, which limits the use of data storage security on any IoT platform. Therefore, in this paper, a data storage security method based on double secret key encryption and Hadoop suitable for any IoT platform is proposed. First, the Hadoop deep learning architecture and implementation process are analyzed, and the process of client Kerberos identity authentication in the Hadoop framework is discussed. From this, the current shortcomings of data storage security based on the Hadoop framework are analyzed. The elements of data storage security are also determined. Furthermore, a novel double secret key encryption method for data storage security and to improve the security of stored data itself is introduced. Simultaneously, hash computing is used to improve the read and write performance of data after secure storage. Experimental results clearly show that our proposed method can effectively improve read and write performance of data, and that the performance of data security operations is improved from current standard implementations.

A key management scheme realising location privacy protection for heterogeneous wireless sensor networks

Key management is the core of wireless sensor network (WSN) security management technology. At present, the protection of the source location information of nodes has also received great attention. In this paper, we combine identity-based encryption (IBE) algorithm with elliptic curve cryptography (ECC) based digital signature authentication to achieve more secure authentication. Then we use the double encryption method to realise the location privacy protection. Finally, we adopt a new routing update scheme to prevent attackers from initiating sinkhole attacks. In addition, we add timestamps to messages transmitted between nodes to defend against resend attacks. The scheme we proposed occupies a small amount of key storage space, consumes relatively more energy to protect the location information of nodes in the heterogeneous sensor network (HSN), and prevents attackers from initiating sinkhole attacks and resend attacks, thereby enhancing network security.

Privacy and Security Aware Cloud Storage using Double Cryptography Method

Cloud computing, a remote technology that enlightens with several on-demand services. Cloud computing developed with a principle of sharing resources available as per the company needs. Prominent cloud services utilized today are networking, storage, servers, software’s, etc. Cloud computing's distributed nature and advanced features create a remarkable footprint in the IT field. It is fair to say without cloud technology the next technical era can't exist. However the cloud computing widely spaced, simultaneous some serious challenges still exists. As per the real-time scenario, there are several challenges still alive, but among which privacy and security are prominent to take concern. Among which the trustworthiness of third-party providers increases the attention on developing an enhanced cloud system. In this paper, we proposed an improved double encryption-decryption (IDED) method for a secure cloud system. The main intention of the proposed work is increasing the privacy and security for the cloud users. The principle applied to the proposed methodology is double encryption and double decryption. The encrypted files are decrypted to view the original data using the keys. These keys are available only to the authenticated users which ensures the system's privacy and security in all manner. The mechanism is processed under the query system of sending and response from the data authority

Security Scheme in Cloud System Using Hyper Elliptic Curve and SIFT Technique with QR Code

When concerned about cloud the security has to be the major factor considered by providers of service. Double encryption is a tool used by the storage server to transfer data by the sender and enhancing the security. The first key performs the identification of the receiver or public key at sender side to generate first-level cipher-text. The other key is stored in the security device issued by SDI (security device issuer) shared with cloud storage systems to originate second-level cipher-text. In the proposed scheme, a file in the cloud is uploaded by the sender and encrypts using the public key, and stores it in the cloud. File in the cloud is visible to the people. Only after the execution of two-step process receiver will be able to access the file. When the user has logged into the application by scanning the QR code in the cloud, the data is sent to the mobile application. As the user passes these step, the shared document is decrypted using a key generated by key generator and user can download the shared file. For each step utmost three attempts are provided, the user will be locked if the user is unable to login during these attempts. A notification facility which enables the user to notify an alert message through e-mail to the concerned user if they exceed more than two attempts or any intruder is trying to access the file is provided. Performance of the system in the cloud environment is analyzed. We present that, encrypted message is sent by a sender to a receiver such that only the receiver’s identity is known by the sender and no other information regarding the data to be accessed. To decrypt the cipher text receiver should perform two-steps. User’s secret key is in the computer and personal security device is connected to it. It is tedious to handle with decrypting the cipher text without either of the above two. This device is revoked In case the security of device is breached. It is not possible to decrypt the cipher text by cloud server.

One-to-many optical information encryption transmission method based on temporal ghost imaging and code division multiple access

A method is presented for one-to-many information encryption transmission by using temporal ghost imaging and code division multiple access. In the encryption transmission process, code division multiple access technologies combine multiple information sources, and the chip sequence corresponding to each set of information is used as the first key. The transmission end loads the transmission information onto a series of temporal random patterns of temporal ghost imaging and transmits it to the receivers. A series of temporal random patterns is the second key. During the decryption, each receiver can get the same encrypted information and use the second key to obtain the transmitted information. Finally, each receiver uses the unique chip sequence to get corresponding information. This encryption transmission method realizes one-to-many information encryption transmission at the same time over the same channel. Double encryption ensures the security of information. Simulation and experiment results verify the effectiveness and security of the method. The method has strong antinoise ability and can effectively resist various attack modes. At the same time, this method solves the problem that the use of code division multiple access enlarges the signal bandwidth, and ensures that no cross talk occurs between various sources of information.
