A secure electronic cash based on a certificateless group signcryption scheme
Many certificateless schemes have been proposed for different purposes, but as for as their applications in any electronic cash schemes there is still a lot of potential for strengthening the security aspect, and this paper is an attempt towards this. In this paper we propose a new type certificateless scheme which is applied for group oriented signcryption rather than a signature without using...
متن کاملOn security of a certificateless signcryption scheme
It would be interesting if a signcryption scheme in the standard model could be made certificateless. One of the interesting attempts is due to Liu et al. [Z. Liu, Y. Hu, X. Zhang, H. Ma, Certificateless signcryption scheme in the standard model, Information Sciences 180 (3) (2010) 452-464]. In this paper, we provide a cryptanalysis on this scheme by depicting two kinds of subtle public key rep...
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 کاملFair Electronic Cash Based on a Group Signature Scheme
Several new group signature schemes have been proposed in recent years. In addition, several applications for group signatures (including electronic cash) have been suggested. A new cash scheme based on a recent group signature by Ateniese, Camenisch, Joye and Tsudik is presented. Its construction uses a general framework suitable for a number of group signature schemes. We also identify the ch...
متن کاملCryptanalysis of a Certificateless Ring Signcryption Scheme
Certificateless public key cryptography (CL-PKC) is an appealing paradigm with the advantages of both conventional public key cryptosystem and ID-based cryptosystem because it avoids using certificates and eliminates the key escrow problem. Ring signcryption is an attractive primitive which allows one user to send a message anonymously, confidentially and authentically. Recently, Qi et al. prop...
