Birthday attack vs collision attack
WebApr 13, 2011 · The birthday attack is a "brute force" attack, since it handles the function as a black box (the preferred term is "generic attack", actually). And there is a massive cost … WebSuch a brute-force attack is based on the birthday paradox, and it would require expected 2^80 computations to produce a SHA-1 collision. Of course, collisions should also be computationally infeasible to find in practice. SHA-1 has been broken in 2005 by a theoretical collision attack. This attack, by Wang, requires expected 2^69 calls to SHA ...
