RIPEMD-160: A strengthened version of RIPEMD [PDF]
International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 1996 Cryptographic hash functions are an important tool in cryptography for applications such as digital fingerprinting of messages, message authentication, and key derivation. During the last five years, several fast software hash functions have been proposed; most of them are based on the design principles of Ron Rivest's MD4. One such proposal was RIPEMD,

Differential Attacks on Reduced RIPEMD-160 [PDF]
Designs, Codes and Cryptography, 2012 In this work, we provide the first security analysis of reduced RIPEMD-160 regarding its collision resistance with practical complexity. The ISO/IEC standard RIPEMD-160 was proposed 15 years ago and may be used as a drop-in replacement for SHA-1 due to their same hash output length.

Analysis of RIPEMD-160: New Collision Attacks and Finding Characteristics with MILP [PDF]
, 2023 The hash function RIPEMD-160 is an ISO/IEC standard and is being used to generate the bitcoin address together with SHA-256. Despite the fact that many hash functions in the MD-SHA hash family have been broken, RIPEMD-160 remains secure and the best ...

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.

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 ...

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.
