A unified architecture of MD5 and RIPEMD-160 hash algorithms [PDF]

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
Hash algorithms are important components in many cryptographic applications and security protocol suites. In this paper, a unified architecture for MD5 and RIPEMD-160 hash algorithms is developed. These two algorithms are different in speed and security level.

Throughput Improvement of RIPEMD-160 Design using Unfolding Transformation Technique [PDF]

, 2022
RIPEMD-160 hash functions are widely used in many applications of cryptography such as digital signature, Hash Message Authentication Code (HMAC) and other data security application. There are three proposed RIPEMD-160 design namely RIPEMD-160 iterative design, RIPEMD-160 unfolding with factor two and RIPEMD-160 unfolding design with factor four. These

High-throughput implementation of the RIPEMD-160

International Journal of Internet Technology and Secured Transactions, 2009
One-way hash functions are the main cryptographic primitives which are used in the network protocols for user authentication and message integration. In the literature, implementations have been proposed either in hardware or software. The rich number of implementations is expected considering the number of constraints of a target application. When the

2-Dimension Sums: Distinguishers Beyond Three Rounds of RIPEMD-128 and RIPEMD-160. [PDF]

IACR Cryptol. ePrint Arch., 2012
This paper presents differential-based distinguishers against ISO standard hash functions RIPEMD-128 and RIPEMD-160. The compression functions of RIPEMD-128/-160 adopt the double-branch structure, which updates a chaining variable by computing two ...

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.

Application of novel technique in RIPEMD-160 aiming at high-throughput

2008 IEEE International Symposium on Industrial Electronics, 2008
Hash functions, form a special family of cryptographic algorithms that satisfy current requirements for security, confidentiality and validity for several applications in technology. Many applications like PKI, IPSec, DSA, MACpsilas need the requirements mentioned before. All the previous applications incorporate hash functions and address, as the time

Improved Semi-Free-Start Collision Attacks on RIPEMD-160 (Full Version). [PDF]

IACR Cryptol. ePrint Arch.
As an ISO/IEC standard, RIPEMD-160 has been extensively studied for (Semi-Free-Start) collision attacks. A significant breakthrough was achieved at FSE 2024 with the first 41-, 42-, and 43-step SFS collision attacks, which leveraged an automatic search ...

SSPSoC: A Secure SDN‐Based Protocol over MPSoC

Security and Communication Networks, Volume 2019, Issue 1, 2019., 2019
In recent years, Multi‐Processor System‐on‐Chips (MPSoCs) are widely deployed in safety‐critical embedded systems. The Cloud‐of‐Chips (CoC) is a scalable MPSoC architecture comprised of a large number of interconnected Integrated Circuits (IC) and Processing Clusters (PC) destined for critical systems.
