Webb16 jan. 2011 · A widely used technique for the construction of cryptographic schemes is the so-called random oracle methodology, introduced in 1993 by Bellare and Rogaway (CCS, 1993). As before, we start with a precise model of security which is extended to include a uniformly random function which may be evaluated by any party ...
