A password represents the initial line of security for the majority of information systems, and plays a pivotal role in the protection of personal information and the security of digital assets. Based on a substantial corpus of password data, this paper employs a data-driven research methodology to analyse the length distribution, structure, and personal information embedded in user passwords, with the objective of elucidating users' susceptible password behaviours. Subsequently, it proffers a series of recommendations to enhance the robustness of passwords. © 2024 IEEE.

The need to simultaneously balance security and fairness in quantum key agreement(QKA) makes it challenging to design a flawless QKA protocol, especially a multiparty quantum key agreement(MQKA) protocol. When designing an MQKA protocol,two modes can be used to transmit the quantum information carriers: travelling mode and distributed mode. MQKA protocols usually have a higher qubit efficiency in travelling mode than in distributed mode. Thus, several travelling mode MQKA protocols have been proposed. However, almost all of these are vulnerable to collusion attacks from internal betrayers. This paper proposes an improved MQKA protocol that operates in travelling mode with Einstein-Podolsky-Rosen pairs. More importantly, we present a new travelling mode MQKA protocol that uses single photons, which is more feasible than previous methods under current technologies.

The paper proposed a wireless access authentication mechanism for unmanned systems, which can effectively solve the problem of secure access authentication under the dynamic change of network topology. The authentication process of cooperative authentication and the realization of secure access were designed to meet the application requirements of random access and anti-attack capabilities. The simulation results showed that the cooperative authentication mechanism not only ensures the security of the unmanned system, but also reduces the transmission overhead and the number of interactive authentications. The network access time is less than 30 milliseconds, and the success ratio of network access is close to 100%. © 2021 IEEE.

Boolean functions can be used in Cryptography (especially, the global avalanche characteristics of one Boolean function is an important property in symmetric Cipher). In this paper, when an n-variable balanced Boolean function satisfies the minimum the sum-of-squares indicator, we give some new properties of (n-1) -variable decomposition Boolean functions. Meanwhile, we derive a new condition on the sum-of-squares indicator, if the sum-of-squares indicator of a balanced Boolean function with n-variable is greater than 22n+2n+3 for ≥ 3. © 2018, ICST Institute for Computer sciences, Social Informatics and Telecommunications Engineering.

Identity authentication and access control are important technologies to realize the security control of the smart park. In this paper, attribute-based access control technology is used to judge whether users can pass the intelligent access control, and new conflict detection and resolution method is proposed for the possible conflict of joint authorization of different park managers. Through theoretical analysis and experimental verification, the attribute-based access control mechanism proposed in this paper can carry out more flexible and fine-grained permission control for users in smart parks. © 2021 IEEE

With the rapid development of mobile Internet and Internet of Things applications, the traditional cloud computing model can provide centralized remote services, but when the amount of data increases sharply, it has been unable to effectively process the data generated by edge devices. To address these challenges and efficiently utilize distributed computing resources, edge computing emerges. With the rise of edge computing, more and more attention has been paid to its security threats and countermeasures. This paper first introduces the basic definition, architectural features, and current security threats of edge computing, then discusses the privacy protection issues in edge computing, and systematically expounds the latest research results at home and abroad. The application of privacy-preserving computing technology in computing, discusses the development trend of edge computing, and proposes further research directions. © 2023 IEEE.

Internet of things need the encryption algorithm with a piece of small area with small-scale. This paper obtains some rotation Boolean permutations by the matrix of linear expressions, and constructs three methods of rotation nonlinear Boolean permutations. The sub-functions of the three permutations have some properties with three monomials, high degree and 2-algebra immunity. Finally, we derive the disjoint spectra Boolean functions. © 2018 Inderscience Enterprises Ltd.

With the rapid development of information technology, information security has become particularly important in the field of communication. To address the limited resources and low computing power of traditional edge platforms, in this paper, an Elliptic Curve Cryptography-based secure communication platform for unmanned systems was developed. Firstly, the platform adopts the Elliptic Curve Cryptography algorithm as the underlying computing support for secure communication. Besides, in its hardware implementation, multi-level pipeline and three-level parallel computing were adopted to achieve high-speed operation of its critical computing. Secondly, in order to increase the flexibility and programmability of the system, for computing on the secure communication protocol layer, the Linux operating system deployed on ZYNQ-7000 SoC is used to achieve programmability and hardware calls to the secure communication protocol. The results show that the ZYNQ-based secure communication platform can complete a dedicated protocol key negotiation in 12.6ms, which is significantly faster than the 28.8ms computing speed based on the same CPU (dual core ARM Cortex-A9) software implementation. It can improve the speed of secure communication while ensuring the flexibility and programmability of unmanned system applications. © 2023 Copyright held by the owner/author(s).

In view of the common edge computing-based cloud-side collaborative environment summary existing search key and authentication key sharing caused by data information leakage, this paper proposes a cryptographic search based on public key searchable encryption in an edge computing environment method, this article uses the public key to search for the characteristics of the encryption algorithm, and allows users to manage the corresponding private key. In the process of retrieval and execution, the security of the system can be effectively ensured through the secret trapdoor. Through the comparison of theoretical algorithms, the searchable encryption scheme in the edge computing environment proposed in this paper can effectively reduce the computing overhead on the user side, and complete the over-complex computing process on the edge server or the central server, which can improve the overall efficiency of encrypted search. © 2021 IEEE
