Universal Designated-Verifier Signature with Aggregation
Third International Conference on Information Technology and Applications (ICITA'05), 2005There is a signature scheme which can aggregate two or more persons' signatures to one, called an aggregate signature. In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier.

Synchronized aggregate signatures
Proceedings of the 17th ACM conference on Computer and communications security, 2010An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signature. Unfortunately, no "fully non-interactive" aggregate signature schemes are known outside of the random oracle heuristic; that is, signers must pass messages between ...

Novel Efficient Certificateless Aggregate Signatures
2009We 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.

Enhanced Aggregate Signatures from Pairings
2005Recently, Boneh et al. proposed the concept of an aggregate signature, introduced security models for such signatures, and also presented some applications. An aggregate signature scheme is a digital signature that supports aggregation: Given n signatures on n distinct messages from n distinct users, it is possible to aggregate all these signatures ...

How to Aggregate the CL Signature Scheme
2011We present an aggregate signature scheme whose public key consists of only two group elements. It is therefore the first sequential aggregate signature scheme with short keys in the standard model. Our construction relies on the Camenisch-Lysyanskaya signature scheme (Crypto 2004) and is provably secure under the LRSW assumption. Moreover, we develop a
