In such a signature scheme, a complicated certification system is discarded and the total length of the message and the appended signature is also shortened. Proxy signature allows an original signer to delegate a proxy signer to sign messages on its behalf, which has found numerous(More)
In this paper, we reinvestigate the security analysis of blind signature scheme over braid groups proposed by Verma in 2008. A blind signature scheme is a cryptographic primitive used for e-commerce for getting a signature from the signer without revealing any information about its contents. These schemes are especially used in e-transactions, e-votings,(More)
