Automating Collision Attacks on RIPEMD-160
IACR Transactions on Symmetric Cryptology, 2023 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 doublebranch structure of RIPEMD-160, the best collision attack only reaches 36 out of 80 steps of RIPEMD-160 ...

A fingerprint encryption scheme based on irreversible function and secure authentication. [PDF]
Comput Math Methods Med, 2015 A fingerprint encryption scheme based on irreversible function has been designed in this paper. Since the fingerprint template includes almost the entire information of users’ fingerprints, the personal authentication can be determined only by the fingerprint features.

Cryptanalysis of 48-step RIPEMD-160
IACR Transactions on Symmetric Cryptology, 2017 In this paper, we show how to theoretically compute the step differential probability of RIPEMD-160 under the condition that only one internal variable contains difference and the difference is a power of 2.

The Applications of Blockchain in the Covert Communication
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Covert communication is designed for hiding the subliminal communication which takes place between both of the speakers and their relationship. The traditional covert communication utilizes the centralized channel and the third‐party central node or authority to distribute messages which leads to a lack of undetectability, antitraceability, and ...

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 Data security is a major issue for smart home networks. Yet, different existing tools and techniques have not been proven highly effective for home networks’ data security. Blockchain is a promising technology because of the distributed computing infrastructure network that makes it difficult for hackers to intrude into the systems through the use of ...

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.
