Abstract: This paper introduces a security analysis scheme for the most famous secure hash algorithms SHA-1 and SHA-2. Both algorithms follow Merkle Damgård structure to compute the corresponding hash ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

For years, SHA-1 was a workhorse in the world of cryptography. It was the go-to hash function for everything from verifying file downloads to securing websites with digital certificates. But today, ...

SHA-1 turned 30 this year—and like many things from 1995, it belongs in a museum, not your production code. Yet programmers worldwide continue generating OTPs and security tokens with this vulnerable ...

With the rapid development of digital communications, sensitive digital storage security, especially that of images, remains a significant challenge. Most of the existing hash algorithms cannot meet ...

This paper proposes a novel approach to design secure hardware IPs of filter bank and QRS complex for implantable cardiac pacemaker, ensuring reliability and safety of patients. The hardware IPs are ...

Password hashing is an essential part of password security. It is an effective and irreversible way to turn your passwords into unintelligible strings of random characters for secure storage and ...

A JavaScript/TypeScript implementation of the complete Secure Hash Standard (SHA) family (SHA-1, SHA-224/256/384/512, SHA3-224/256/384/512, SHAKE128/256, cSHAKE128/256, and KMAC128/256) with HMAC.

Marriot revealed in a court case around a massive 2018 data breach that it had been using secure hash algorithm 1 and not the much more secure AES-1 encryption as it had earlier maintained. For more ...

The three newly-enacted criminal laws, the Bharatiya Nyay Sanhita (to replace the Indian Penal Code), the Bharatiya Nagarik Suraksha Sanhita (to replace the Code of Criminal Procedure) and the ...
