WebCRYPTREC（くりぷとれっく、Cryptography Research and Evaluation Committees) とは、電子政府推奨暗号の安全性を評価・監視し、暗号技術の適切な実装法・運用法を調査・ … WebRIPEMD ( RIPE Message Digest) is a family of cryptographic hash functions developed in 1992 (the original RIPEMD) and 1996 (other variants). There are five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, of which RIPEMD-160 is the most common.

Security Evaluation of SHA-224, SHA-512/224, and SHA …

WebSHA-1 round, and finally two register variables of SHA-2 are substantially mod-ified at each round compared to only one for SHA-1. The SHA-2 round function is the same for all rounds except for the use of distinct constants Kt at each round, whereas SHA-1 involves four different types of round functions used in a subset of 20 consecutive ... WebSHA-256, we show that the low probability of a single local collision may give rise to a false sense of security. 1 Introduction After recent cryptanalytic results on MD5 [20], SHA-1 [2,15,19] and similar hash functions, the resistance of members of the SHA-2 family (i.e. SHA-224, SHA-256, SHA-384 and SHA-512) [13] against recent attacks is an ... philomath school board
