Novel Efficient Certificateless Aggregate Signatures
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
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. ...
Subsequently, a new CLAS scheme was proposed in [10] and proven secure in a stronger security model. ...
