Identity-Based Proxy Signcryption Schemes
Abstract:
Identity-based encryption and signature schemes that allow any pair of users to communicate securely and to verify each other's signatures without verifying certificate. A signcryption is a primitive that provides the properties of both digital signatures and encryption schemes in a way that is more efficient than signing and encrypting separately. Proxy signature schemes are a variation of ordinary digital signature scheme that allow a proxy signer to sign messages on behalf of the original singer which proxy signcryption simultaneously fulfill both the functions of signature and encryption in a single step with a lower computational cost than that required by the traditional signature-then-encryption. In this paper, we present identity-based proxy signcryption schemes with lower efficient..
