Novel Efficient Certificateless Aggregate Signatures

2009
We propose a new efficient certificateless aggregate signature scheme which has the advantages of both aggregate signatures and certificateless cryptography. The scheme is proven existentially unforgeable against adaptive chosen-message attacks under the standard computational Diffie-Hellman assumption.

An Efficient Certificateless Signature Scheme

2005
Traditional certificate based cryptosystem requires high maintenance cost for certificate management. Although, identity based cryptosystem reduces the overhead of certificate management, it suffers from the drawback of key escrow. Certificateless cryptosystem combines the advantages of both certificate based and identity based cryptosystems as it ...

Generic Construction of Certificateless Signature

2004
To provide the binding between a user and his public key, traditional digital signature schemes use certificates that are signed by a trusted third party. While Shamir’s identity-based signature scheme can dispense with certificates, the key escrow of a user’s private key is inherent in the identity-based signature scheme.

Simple Certificateless Signature with Smart Cards

2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing, 2008
A certificateless public key cryptosystem (CL-PKC) was proposed for the first time in 2003, and since then it has been attracted. But in fact most CL-PKC is implemented using the pairing technique. So it is difficult so far to apply CL-PKC to an existing encryption system that uses the conventional encryption method such as RSA.
