The term crypto-agility means the ability to quickly and securely change cryptographic algorithms and related data, in the case of their compromise. In this context, the advent of quantum computing constitutes a new paradigm, which poses existential threats to current cryptographic algorithms. Even if these attacks are not an imminent danger, we must be prepared to change the cryptographic algorithms at risk with new, quantum resistant ones. This is by no means an easy task, because cryptographic algorithms are used everywhere and are often also implemented on the hardware. In this paper, we analyze the similarities and the differences between traditional agility and crypto-agility, and investigate the prospects of using agile and lean practices in the context of crypto-agility to introduce quantum resistant algorithms. In particular, for the main agile and lean practices we discuss if and how they can be useful for obtaining crypto-agility. We also investigate how the features key to crypto-agility can be helped by the agile and lean approach.

Usually a complete computer network system has the following components: source of signals, signal host, cryptographic regime, attack, and interceptor. It is more vulnerable to attacks during the operation of the system, so the security of the system becomes more important. In this paper, by constructing a dual BP neural network combinatorial model and applying it to the computer data communication large integer decomposition encryption process, the constructed model is used to analyze the security against digital certificates, digital signatures, and the algorithms employed in the communication process of connected computer network.

In today’s fast-evolving technological environment, ensuring confidentiality is of utmost importance. Cryptography stands as a critical discipline in safeguarding information from unauthorized access. It employs various encryption algorithms to secure data effectively. As digital threats evolve, there’s a growing demand for unconventional encryption methods to counter traditional cyber-attacks. This paper introduces innovative encryption algorithms leveraging special graphs and public key cryptography techniques, enhancing security through modular arithmetic properties and enabling more robust communication safeguards. A partition V1, V2,…, Vk of the vertex set V is called a chromatic partition of G if each Vi, 1 ≤ i ≤ k is an independent set of G. The minimum order of a chromatic partition of G is called chromatic number χ(G). A chromatic partition of G is called an ordered partition if |V1| = β0 and |Vi| = β0(V − ∪j=1i Vj ). The order of a minimum ordered chromatic partition of G is called ordered chromatic number χ1(G). It is immediate that χ1(G) ≥ χ(G). In this paper we extend Nordhaus Gaddum results to ordered chromatic number. © (2024), (International Association of Engineers). All Rights Reserved.

In this paper, we propose an audio encryption scheme that supports differentiated decryption, called AES-AUDIO, in which an audio only needs to be encrypted once and can be decrypted into different resolutions as needed. First, we design four security levels, confidential, harsh, noisy, and clear, based on the audio resolution perceived by human auditory perception. Second, the audio data in decimal floating-point numbers (D-FPNs) are unfolded to 32 bits (B-FPNs). Third, we design a region of interest (RoI) encryption algorithm for the audio with the B-FPN format, where the result preserves some perceptual information as needed. Fourth, we construct the AES-AUDIO scheme based on the RoI encryption algorithm, which allows the audio to be encrypted once and then decrypted into different security levels. It supports changing parameters to alter the perception effect corresponding to the security level. Overall, it achieves a balance between the security and usability of the protected audio. User experiments verify that the audios produced by differential decryption can achieve the expected security levels. Some security tests also yielded excellent results, such as an NSCR value of 1. © 1999-2012 IEEE.

During the last few years critical advancements in Wireless Sensor Networks (WSNs) have highlighted respective platforms as a prominent technology able to tackle various challenges posed by Smart-City application scenarios. However, a critical area that has not been adequately taken into consideration concerns security provision necessity in conjunction to its impact on real WSN platform communication efficiency. Consequently, specific practices must be defined in alignment with, up to date, regulations and legislation. In this paper, a two-fold contribution is made. On one hand, a comprehensive study is presented focusing on practices that a real WSN must follow so as to comply with the current security and privacy regulations and legislations. On the other hand, a system level evaluation is presented emphasizing on the effect of security algorithms utilization upon the behavior and performance of a prominent real WSN environment. This evaluation is based on experimentations using a prominent WSN platform enabling algorithms offering high level security features while varying a wide range of critical network parameters.

security and the privacy features concerning e-banking needs to be improved rapidly to continue its growing. It is really difficult to ensure enough adequate security by using the conventional algorithms for a long time period, due to recent advances such as high progress in cryptanalysis techniques, improvement of computing skills and continuous hacking trials. This paper refers important issues regarding how to enhance the transition to more secure cryptographic and encryption algorithms in the financial sector. This paper recommends that adopting and implementing open source applications following international standards can be considered as a good replacement to the conventional algorithms to offer more enhancement security techniques and highest performance encryption algorithms for e-banking transaction services. We proposed a modified algorithm for AES, in which substitute byte, shift row will remain as in the original AES while mix column operation is replaced by 128 permutation operation followed by add round key operation. Comparative study with traditional encryption algorithms is shown the superiority of the modified algorithm and its high ability to overcome the problem of computational overhead. We additionally suggested another level of e-banking security services using Confidence Building Metric (CBM). The CBMs are computed based on certain parameters and can be implemented on any platform at the client side.

During the last few years critical advancements in Wireless Sensor Networks (WSNs) have highlighted respective platforms as a prominent technology able to tackle various challenges posed by Smart-City application scenarios. Through their communication paradigm and platform versatility WSNs are able to meet increasingly demanding communication requirements. However, a critical area that has not been adequately taken into consideration concerns security provision necessity in conjunction to its impact on real WSN platform communication efficiency. Actual deployment of WSNs in the context of Smart-Cities' scenarios implies the handling of personal and sensitive information. Consequently, specific practices must be defined in alignment with, up to date, regulations and legislation. At the same time offering the required security level implies the use of demanding techniques and algorithms which must pose acceptable performance burden on the platform thus negatively affecting the overall communication efficiency. In this paper a two-fold contribution is made aiming to enhance in-depth understanding on the two aforementioned aspects of security provision. Therefore, on one hand a comprehensive study is presented regarding soft issues of security provision focusing on practices that a real WSN must follow so as to comply with respective regulations and legislations. On the other hand, a comprehensive system level evaluation is undertaken and presented emphasizing on the effect of state-of-the-art security algorithms utilization upon the behavior and performance of a prominent real WSN environment. This evaluation is based on experimentations using a prominent WSN platform enabling algorithms offering high level security features while varying a wide range of critical network parameters. Without a doubt both aspects offer significant conclusions and insight that on-going and future WSN deployments must take into consideration when aiming to be used in real Smart City deploy
