Without this - feature, an attacker could degrade performance of a targeted - client or server by flooding their data structures with a large - number of data entries all calculated to be stored at the same - hash table position, thereby degrading hash table - performance. With this feature, hash table positions are derived - from a randomized cryptographic key using SipHash-2-4, and an - attacker cannot predict which entries will collide. - Closes ticket 4900. |
