This paper studies the security of SHA-256, SHA-384 and SHA-512 against collision attacks and provides some insight into the security properties of the basic building blocks of the structure. It is concluded that neither Chabaud and Joux’s attack, nor Dobbertin-style attacks apply.

WebSHA-2 is actually four functions: SHA-224, SHA-256, SHA-384, and SHA-512. On 12 August 2004, Joux, Carribault, Lemuet, and Jalby announced collisions in SHA-0. On 17 August 2004, Xiaoyun Wang independently presented collisions in MD5 and faster collisions in … WebThis paper studies the security of SHA-256, SHA-384 and SHA-512 against collision attacks and provides some insight into the security properties of the basic building blocks of the …
WebIn cryptography and computer security, a length extension attack is a type of attack where an attacker can use Hash ( message1) and the length of message1 to calculate Hash ( message1 ‖ message2) for an attacker-controlled message2, without needing to know the content of message1.
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 ...

WebSHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher..
