Security Analysis and Implementation of an Improved Cch2 Proxy Multi-Signature Scheme
2014
International Journal of Computer Network and Information Security
Many of the signature schemes are proposed in which the t out of n threshold schemes are deployed; but they still lack the property of security. In this paper, we have discussed implementation of improved CCH1 and improved CCH2 proxy multi-signature scheme based on elliptic curve cryptosystem. We have represented time complexity, space complexity and computational overhead of improved CCH1 and CCH2 proxy multi-signature schemes. We have presented cryptanalysis of improved CCH2 proxy
