摘要: 结合代理签密和自认证签密的理论,构造了一个基于pairings的自认证多接收者代理签密方案.由于用户公钥具有自认证性,无需权威机构签发证书,同时用户私钥也只有自己知道,因此,与已有文献相比,此方案具有很好的安全性和实用性.Abstract: By merging the theory of proxy signcryption and self-certified signcryption, a multi-receipt proxy signcryption scheme from pairings based on self-certified cryptosystem is constructed.The public key of the user has self-certified characteristic, the system authority (SA) does not require to sign and issue the certificate, simultaneously only the user knows his own private key.The constructed has better security and more practical value than the existing literatures.
