A Provably Secure Certificateless Proxy Signature Scheme
Proxy signature, a variant of digital signature, is in the limelight in recent years for secure communication. For instance, when a manager is occupied with business matters, or travelling on business, he has to delegate an agent to deal with his day-today office concerns. Therefore, a proxy signature scheme is necessary in this scenario. Although identity-based proxy signature schemes have bee...
متن کاملAn efficient certificateless signcryption scheme in the standard model
Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...
متن کاملEfficient Certificateless Signcryption Scheme
In this paper, we propose a certificateless signcryption scheme from Weil pairings and give a practical security model. Compared with existing schemes, the new scheme is more efficient.
متن کاملA Provably Secure Proxy Signature Scheme in Certificateless Cryptography
A proxy signature scheme enables an original signer to delegate its signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original signer. Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity-based cryptography, the notion of certificateless public key cryptography was int...
متن کاملA Provably Secure Proxy Signcryption Scheme Using Bilinear Pairings
As people in modern societies are busier than any human era and computer network has profound impact on how people work and live through fast and convenient information exchange, people need more help from each other to accomplish more work via network connections in limited period of time. Therefore, privilege delegation mechanism has become a necessary service in modern enterprises and organi...
