标准模型下高效的代理签名方案
Efficient Proxy Signature Scheme in Standard Model
摘要
Abstract
A proxy signature allows original signer to delegate his signing capability to the proxy signer in such a way that the proxy signer can sign messages on behalf of the original signer. This paper proposes a new probably secure signature scheme in the standard model. The security of new scheme is based on the intractability of q-strong Diffie-Hellman problem. The scheme is proved secure against existential forgery in adaptively chosen message attack in the standard model. Compared with existing schemes, the proposed scheme which needs less public parameters with a tight security reduction has obvious advantages in generating secret key, standard signing, proxy signing and generating delegation, etc.关键词
