“…The advantage of ID based schemes is that it abstains the use of certificates, which is generally a overhead when there are large number of vehicles deployed on the road. However, the disadvantage of ID based schemes id that, it suffers from key escrow problem [58].…”

Vehicular Ad hoc Network (VANET) is a versatile and ad hoc network, where the vehicles must be authenticated before sharing any critical information. During authentication, privacy of the users must be preserved. There are several surveys on privacy-preserving authentication schemes in VANET. However, none of them are focused on the ability of the schemes to address different security issues and their robustness against security attacks. In this paper, we present a review on various privacy-preserving authentication schemes in VANET. These schemes may be categorized into several types like symmetric/asymmetric key cryptography based schemes, digital signature based schemes, ID cryptography based schemes, pseudonym based schemes, homomorphic encryption based schemes and blockchain based schemes. A comprehensive study of the prominent schemes, with regards to their effectiveness in addressing different security issues and their robustness against possible attacks, has been performed. Open issues and scope for future work are also highlighted.

“…Digital or literal, Log file or raw data, the PPCT can be applied easily on the different types of transaction unlike other confidentiality protocols that are restricted to numerical data to perform calculations or to some private data to represent identity [32]. In our case, just choose the right Symmetric Encryption algorithms that perform better on the volume and types of data to be exchanged to improve the performance of the protocol [33].…”

Running behind new technologies is increasingly becoming a non-circumventable requirement for organisms' survival. This is not only a strategy to gain a competitive advantage in the market but it is a determinant key for their continuity and persistence. The Blockchain is at the heart of this technological revolution for which transparency, accessibility to the public and the sense of sharing are fundamental properties of its design. Despite its importance, leveraging this technology in an ethical and secure manner by ensuring confidentiality and privacy is a top concern. Through this work, we try to design a new approach to validate transactions within the Blockchain. Entitled "Protocol for Partial Confidentiality & Transparency PPCT", this new protocol makes possible to seek a compromise between the two requirements: Confidentiality & Transparency. It allows introducing a new notion of confidentiality that we have named partial confidentiality. Subsequently, it applies it on the transactions exchanged while ensuring the process of their validations by the different nodes of the Blockchain. In addition, and through the use of hashing and digital signature functions, this protocol also ensures integrity and authentication within its validation process. To present this work, we will first discuss the state of the art on the different current privacy approaches and our motivation behind this work. Then we will explain more about the different stages of this process, its benefits and areas for improvement.

“…Furthermore, digital communication systems prefer exchanging encrypted messages to sending confidentiality plaintexts [19]. However, in schemes based on public-key encryption, a sender's public key is openly accessible; as a result, anyone can spoof it and transmit an encrypted message to the receiver [20]. As a result, users manipulating public key cryptography for encryption must acquire digital signatures amongst encrypted data to ensure message authentication and non-repudiation.…”

The emergence of the Internet of Things (IoT) represents a significant trend, where integrating IP, data, and wireless technologies onto a single network yields substantial advantages that are both essential and appealing. However, the amalgamation of these entities introduces novel susceptibilities and opportunities for infiltrating IoT networks, thereby necessitating the perpetual advancement of integrated security methodologies. This study investigates the feasibility of utilizing the Rivest-Shamir-Adleman (RSA) method, based on the Miller-Rabin technique, as a stream key generator with five distinct hashing functions to attain robust digital signatures. The RSA encryption method underwent a comprehensive battery of tests to assess its validity, and its encryption efficacy was evaluated through mathematical analysis. This research examines the assessment of digital signatures by utilizing five distinct hash functions in conjunction with RSA keys. Each signature file was assessed based on four tests: entropy, floating frequency, autocorrelation, and histogram analysis. The tests were conducted on a document with a size of 256 bytes. In addition, nine hash algorithms were utilized, namely SHA224,
