一种基于双线性对的前向安全代理签名方案
Forward-secure Proxy Signature Scheme Based on Bilinear Pairings
摘要
Abstract
By combining the bilinear pairings,forward-secure digital signature and proxy signature, a forward secure proxy signature scheme based on bilinear pairings was proposed. The new scheme made up the insufficiency of Ju Shang you's scheme in that even if at a certain moment proxy signature key is exposed the proxy signature before the momnet is still valid. The security proof shows that the new scheme not only has forward security,but also meet all safety requirements of strong proxy signature scheme; in addition, the sheme,with bilinear pairings as a tool,shows higher efficiency than RSA and discrete logarithm signature scheme.关键词
