Algorithmic compexity attacksAlgorithmic compexity attacksPosted Jun 5, 2003 11:43 UTC (Thu) by fergal (subscriber, #602)In reply to: Algorithmic compexity attacks by NRArnot Parent article: Algorithmic compexity attacks Using some random element may help but the scheme you gave as an example doesn't help. With the XOR hash, if two strings A and B hash to the same value then they'll still hash to the same value when they have the random byte appended. Using md5 instead of XOR would prevent that. So it's a good solution but it still depends on have a good algorithm.
