Short signature based on factoring problem in the standard model
摘要
Abstract
A short signature scheme based on factoring problem in the standard model was proposed. To design this signature scheme, the generic construction of fully-secure signatures from weakly-secure signatures and a chameleon hash were employed. A signature in this scheme was compromised of one element in Z*N, and the public key was short, requiring only the modulus N, one element of Z*N, one integer and one pseudorandom function seed. Compared with Hohenberger's RSA scheme (Crypto 09), the computaional cost of the sign algorithm and verification algorithm in this scheme is also much lower.关键词
