Efficient design of Certificateless Chameleon Signature from Bilinear Pairing
Certificateless public key cryptography (CL-PKC), does not require the use of the certificate to guarantee the authenticity of public keys. It does rely upon the use of a trusted third party (TTP), who is in possession of a master key. CL-PKC does not suffer from the key escrow property. Thus, CL-PKC can be seen as a model for the use in public key cryptography. In this paper, we proposed a new...
متن کاملChameleon Signature from Bilinear Pairing
Xinjun Du, Ying Wang, Jianhua Ge and Yumin Wang Key Laboratory of Computer Networks and Information Security Xidian University Abstract: Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chameleon signatures is that there are non-transferable, with only the designated recip...
متن کاملCertificateless threshold signature scheme from bilinear maps
A (t,n) threshold signature scheme allows t or more group members to generate signatures on behalf of a group with nmembers. In contrast to the traditional public key cryptography based on public key infrastructure (PKI) and identity-based public key cryptography (IDPKC), certificateless public key cryptography (CL-PKC) offers useful properties as it does not require any certificates to ensure ...

متن کاملEfficient Certificateless Signcryption from Bilinear Pairings
Certificateless public key cryptography is an attractive paradigm which combines advantages of both traditional certificate-based and ID-based public key cryptosystems. In this paper, the author formalizes the definition and the security model for certificateless signcryption (CLSC), and proposes a CLSC scheme that is proved to be secure in the random oracle model. The CLSC scheme satisfies suc...
