In the literature, different types of algorithms that are organised to encrypt and decrypt images have been introduced. Some of these depend on chaotic systems where bifurcation routes to chaos exist. Those algorithms have advantages and disadvantages so far as their security level and computational speed are concerned. This study proposes a robust algorithm based on a pixel shuffling and a one-dimensional chaotic economic map for encrypting and decrypting images. The proposed algorithm is implemented on many images. The security and performance of the proposed method are analysed thoroughly by using key space, key-sensitivity, correlation of two adjacent pixels, information entropy, contrast and differential attack. On the basis of the obtained experimental results, the proposed algorithm is characterised by a large size of key space, a high sensitivity to the secret key, very low correlation coefficients, a good information entropy and a high contrast. Finally, the experiments are confirmed that the proposed algorithm can resist statistical and differential attacks with high efficiency.

Mobile ad-hoc networks (MANETs) play an important role in the future of the industrial internet-of-things communication, where smart devices will be connected in a completely distributed manner. In the digital properties owing to the digital data properties, there exist difficulties in directly applying the encryption schemes to the one-dimension data. Thus, it is necessary to develop secure lightweight key frame extraction technique for improving privacy in the e-healthcare. This paper plans to develop the robust and reliable security protocol in MANET IoT application. A chaotic cryptography-based privacy preservation model is proposed in this paper for the purpose of improving the security in the MANET IoT. The key generation process in the chaotic map is optimized by generating optimal key pairs through the newly developed SA-SFO algorithm. The key selected from the chaotic map is influenced by selecting the optimal parameters through the proposed Self Adaptive Sail fish Optimization (SA-SFO). Finally, the experimental analysis is conducted, where for the case of character length as 100;the proposed SA-SFO eventually surpassed the existing ones with the cost function 22% as higher than PSO, 20% higher than GWO, 19% higher than WOA, and 21% higher than SFO respectively. The comparative analysis over the conventional models ensures the efficient performance of the proposed model in terms of diverse analysis in MANET and IoT platform.

Cryptography is a core component of many security applications, and flaws hidden in its implementation will affect the functional integrity or, more severely, pose threats to data security. Hence, guaranteeing the correctness of the implementation is important. However, the semantic characteristics (e.g., diverse input data and complex functional transformation) challenge those traditional program validation techniques (e.g., static analysis and dynamic fuzzing). In this article, we propose CLFuzz, a semantic-aware fuzzer for the vulnerability detection of cryptographic algorithm implementation. CLFuzz first extracts the semantic information of targeted algorithms including their cryptographic-specific constraints and function signatures. Based on them, CLFuzz generates high-quality input data adaptively to trigger error-prone situations efficiently. Furthermore, CLFuzz applies innovative logical cross-check that strengthens the logical bug detection ability. We evaluate CLFuzz on the widely used implementations of 54 cryptographic algorithms. It outperforms state-of-the-art cryptographic fuzzing tools. For example, compared with Cryptofuzz, it achieves a coverage speedup of 3.4x and increases the final coverage by 14.4%. Furthermore, CLFuzz has detected 12 previously unknown implementation bugs in 8 cryptographic algorithms (e.g., CMAC in OpenSSL and Message Digest in SymCrypt), most of which are security-critical and have been successfully collected in the national vulnerability database (7 in NVD/CNVD) and is awarded by the Microsoft bounty program (2 for $1,000).

In this paper a VHDL implementation of the Hummingbird lightweight cryptographic algorithm is presented, with the initialization, encryption and decryption processes analyzed and simulated. All these processes include stream cipher and block cipher encryption or decryption techniques, such as transposition with linear transform and substitution with Substitution box (Sbox). These techniques are described in detail, and a full paradigm is presented. The Hummingbird algorithm exploits the extra safety provided by the Linear Feedback Shift Register (LFSR). Such a circuit is fully designed and analyzed, demonstrating a reliable and well performed system that can implement a successful encryption/decryption process. The analysis of both the forward and the reverse procedure are described together with a case study, using suitable programming via the Xilinx Design Suite. Following the analysis of the Hummingbird algorithm, the LFSR circuit and the whole decryption process circuit are designed from scratch. The results of the simulation proved the reliable execution of the algorithm.

In modern society, especially on the Internet, you might have found you are having more and more usernames or IDs and passwords, which contains your private information. There are too many for you to remember and it is unsafe to write them down on you notebook. To solve this problem, this paper made a design and implementation of Passwords Management System (PMS), by which you can manage your usernames and passwords efficiently. It was made based on Blowfish algorithm, which is a symmetric block cipher and designed by Bruce Schneier in 1993. Firstly, the paper made an introduction of the theory and advantages of Blowfish Encryption algorithm, described some important details of its encryption process, and then designed and implemented the PMS.

The cloud environment is recently emphasized when we save a large amount of data with a minimum of maintenance. But the cloud is a variable environment that data is likely to be changed when which is transferred, and even doesn't permanently store. Besides it has the risk of phishing from a third party. A scalable storage space as one of the features of the cloud has to consist as more proactive access control, secure encryption, and key management in the aspect of the size of the database and the number of users. In this paper, we analyze about database security requirements of these environment and the provided encryption technologies of until now. And, even anyone who don't have the expertise for security assessment and management or CC could be easily accessible it.

Recently, computing-in-memory (CiM) becomes a promising technology for alleviating the memory wall bottleneck. CiM is suitable for data-intensive applications, especially, cryptographic algorithms. Most current cryptographic accelerators are specific to a single function. It is expensive to accelerate different cryptographic algorithms with different accelerators. In this work, we first introduce a CiM architecture FeMIC that supports multioperand CiM operations, by exploring advantages of state-of-the-art ferroelectric field-effect transistors. Based on that, we propose a novel instruction set together with an accelerator architecture named FeCrypto which supports the acceleration of various cryptographic algorithms. Evaluation results show that FeCrypto has better performance and energy efficiency than software implementations. The energy-delay product (EDP) of FeCrypto is 118.4x and 1.93x lower than that of the dedicated AES accelerator AIM that is built based on phase-change memories (PCMs) and magnetic random-access memories (MRAMs), respectively. EDP is reduced by 44.7x compared with PCM-based EIM, a recent AES accelerator. Compared with MRAM-based EIM, the EDP overhead of FeCrypto for supporting multiple functions is 23.2%.
