| Abstract （English） |
Hash functions play very important role in the field of cryptography and its applications.Especially, hash functions which have collision free property is needed in cryptographic protocols like electronic cash protocols.In this paper, we show the proof of security for combination of hash functions which are elements of collision free hash function family.Moreover, we present a new method for constructing accumulator with the proof of security. |
