    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...

    Empirical Study on Taxi GPS Traces for Vehicular Ad Hoc Networks

    Inter-contact time between mobile nodes that captures the temporal characteristics of Vehicular Ad Hoc NETworks (VANETs) has been intensively studied. Whereas the node spatial distribution is ignored in most existing mobility schemes, which is also worthy of investigation, particularly for real applications. Moreover, the node spatial distribution has a significant...

    On Security of a Certificateless Aggregate Signature Scheme

    Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. Very recently, Xiong et al. proposed a certificateless aggregate signature scheme provably secure in the random oracle model under the Computational Diffie-Hellman assumption. Unfortunately, by giving two...

    Novel Efficient Certificateless Aggregate Signatures

    The notion of newly introduced aggregate signatures allows an efficient algorithm to aggregate n signatures of n distinct messages from n different signers into one single signature. The authors propose a new efficient certificateless aggregate signature scheme which has the advantages of both aggregate signatures and certificateless cryptography. The scheme...

    Secure Certificateless Public Key Encryption Without Redundancy

    Certificateless public key cryptography was introduced to solve the key escrow problem in identity based cryptography while enjoying the most attractive certificateless property. In this paper, the authors present the first secure CertificateLess Public Key Encryption (CLPKE) scheme without redundancy. The construction provides optimal bandwidth and quite efficient decryption process...
