Blockchain as a CA: A Provably Secure Signcryption Scheme Leveraging Blockchains
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Although encryption and signatures have been two fundamental technologies for cryptosystems, they still receive considerable attention in academia due to the focus on reducing computational costs and communication overhead. In the past decade, applying certificateless signcryption schemes to solve the higher cost of maintaining the certificate chain ...

BBAAS: Blockchain‐Based Anonymous Authentication Scheme for Providing Secure Communication in VANETs
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Smart driving has become conceivable due to the rapid growth of vehicular ad hoc networks. VANETs are considered as the main platform for providing safety road information and instant vehicle communication. Nevertheless, due to the open wireless nature of communication channels, VANET is susceptible to security attacks by malicious users.

Automating Collision Attacks on RIPEMD-160 [PDF]
As an ISO/IEC standard, the hash function RIPEMD-160 has been used to generate the Bitcoin address with SHA-256. However, due to the complex double-branch structure of RIPEMD-160, the best collision attack only reaches 36 out of 80 steps of RIPEMD-160 ...

Collisions and Semi-Free-Start Collisions for Round-Reduced RIPEMD-160 [PDF]
, 2018 In this paper, we propose an improved cryptanalysis of the double-branch hash function RIPEMD-160 standardized by ISO/IEC. Firstly, we show how to theoretically calculate the step differential probability of RIPEMD-160, which was stated as an open ...
