A Revocable Certificateless Signature Scheme
Certificateless public key cryptography (CLPKC), with properties of no key escrow and no certificate, has received a lot of attention since its invention. However, membership revocation in certificateless cryptosystem still remains a non-trivial problem: the existing solutions are not practical for use due to either a costly mediator or enormous computation (secret channel). In this paper, we p...
متن کاملA Revocable Certificateless Short Signature Scheme and Its Authentication Application
Certificateless short signature (CLSS) possesses the advantages of both certificateless signature and short signature. CLSS eliminates the certificate management in conventional signatures and solves the key escrow problem in ID-based signatures. In the meantime, due to its short signature length, CLSS reduces the bandwidth for communication so that it is suitable for some specific authenticati...
متن کاملA Revocable Online-Offline Certificateless Signature Scheme without Pairing
Certificateless Public key Cryptography is a widely studied paradigm due to its advantages of not having the key-escrow problem and the lack of use of certificates. Online-Offline signature schemes are extremely relevant today because of their great practical applications. In an online-offline signature scheme all the heavy computation is done on powerful processors and stored securely in the o...
متن کاملLattice-Based Revocable Certificateless Signature
Certificateless signatures (CLS) are noticeable because they may resolve the key escrow problem in ID-based signatures and break away the management problem regarding certificate in conventional signatures. However, the security of the mostly previous CLS schemes relies on the difficulty of solving discrete logarithm or large integer factorization problems. These two problems would be solved by...
متن کاملCertificateless undeniable signature scheme
The concept of certificateless public key cryptography (CL-PKC) was introduced by Al-Riyami and Paterson. Such a cryptosystem does not suffer from the key escrow problem while avoiding the onerous management of certificates. In this paper, we present the first certificateless undeniable signature scheme. We consider two different types of adversaries and formalize the security notions for certi...
