Abstract |
The one-time proxy signature scheme is a kind of digital signature scheme. Using the signature scheme, the original signer can delegate his/her signing capability to the proxy signer and the proxy signer can sign the message only once. In this paper, we propose a new one-time proxy signature scheme based on Discrete Logarithm Problem(DLP). The proposed scheme uses Wang's basic proxy signature and the warrant. Because our one-time proxy signature scheme satisfies all security properties, the scheme is secure. Furthermore, we extend our scheme for multiple signing. |
