An efficient certificateless short signature scheme from pairings
نویسنده
چکیده
To avoid the inherent key escrow problem in ID-based public key cryptosystem, Al-Riyami and Paterson introduced a new approach called certificateless public key cryptography. Recently, several short certificateless signature schemes are presented to improve the performance. In this paper, we propose an efficient short certificateless signature scheme which is secure against the super adversary. Compared with the related scheme, our scheme has the best performance in both sign algorithm and the verify algorithm.

An efficient and provably-secure certificateless signature scheme without bilinear pairings
Many certificateless signature schemes using bilinear pairings have been proposed. But the relative computation cost of the pairing is approximately twenty times higher than that of the scalar multiplication over elliptic curve group. In order to improve the performance we propose a certificateless signature scheme without bilinear pairings. With the running time being saved greatly, our scheme...
متن کاملEfficient and provably-secure certificateless short signature scheme from bilinear pairings
In this paper, we present a certificateless signature (CLS) scheme that is proved to be secure in the random oracle model under the hardness assumptions of k-CAA and Inv-CDHP. Our scheme upholds all desirable properties of previous CLS schemes, and requires general cryptographic hash functions instead of the MapToPoint hash function which is inefficient and probabilistic. Furthermore, our schem...
متن کاملTruly Non-Repudiation Certificateless Short Signature Scheme from Bilinear Pairings
Certificateless signature scheme is a practical solution to confront the drawback, Key Generation Center (KGC) being able to forge the signature of a user, of an identity based (ID-based) signature scheme. Lots of previous research results have shown the security models and the generic constructions for certificateless signatures. However, most of them did not satisfy Girault’s level-3 security...
متن کاملAn efficient certificateless designated verifier signature scheme
To solve the key escrow problem in identity-based cryptosystem, Al-Riyami et al. introduced the CertificateLess Public Key Cryptography (CL-PKC). As an important cryptographic primitive, CertificateLess Designated Verifier Signature (CLDVS) scheme was studied widely. Following Al-Riyami et al. work, many certificateless Designated Verifier Signature (DVS) schemes using bilinear pairings have be...
متن کاملToward Efficient Certificateless Signcryption from (and without) Bilinear Pairings
In this paper we describe how to construct an efficient certificateless signcryption scheme. Contrary to the usual paradigm of converting identitybased encryption and signature schemes into a combined certificateless protocol, we adopt the approach of extending a conventional signcryption method with a certificateless key validation mechanism, resorting to the underlying identity-based techniqu...
