Synchronized aggregate signatures

Proceedings of the 17th ACM conference on Computer and communications security, 2010
An 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 ...

Hybrid Aggregate Signature Scheme: A New Type Aggregate Signature Scheme

2009 Second International Conference on Information and Computing Science, 2009
An aggregate signature scheme is a digital signature scheme that supports aggregation: Given n ordinary signatures on n distinct messages from n distinct ordinary signers, it is possible to aggregate all these signatures into a single short signature.

Compact sequential aggregate signatures

Proceedings of the 2007 ACM symposium on Applied computing, 2007
In this paper, a new notion which we call compact sequential aggregate signatures is introduced and formalized. Informally, a compact sequential aggregate signature states the following thing: for a given message vector m=(m1, · · · mι), a public key vector PK=(PK1, · · · , PKι) and a path p=(v1, · · · , vι), where vi=(idi, PKi), the size of the third ...

Certificateless Aggregate Signature Scheme

2010 International Conference on E-Business and E-Government, 2010
This paper puts forward a secure construction of certificateless aggregate signature scheme using bilinear maps. The security of our scheme is based on the infeasibility of the Computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless aggregate signature schemes.

Attribute Based Sequential Aggregate Signature

2013 International Conference on Cloud Computing and Big Data, 2013
Attribute based signature (ABS) scheme is an important cryptographic primitive which provides a powerful way for user to control their privacy. However, the computational and storage cost of ABS is reasonable when the number of users involved in the system is huge.

Fault-Tolerant Aggregate Signatures

2016
Aggregate signature schemes allow for the creation of a short aggregate of multiple signatures. This feature leads to significant reductions of bandwidth and storage space in sensor networks, secure routing protocols, certificate chains, software authentication, and secure logging mechanisms. Unfortunately, in all prior schemes, adding a single invalid

Certificate-based sequential aggregate signature

Proceedings of the second ACM conference on Wireless network security, 2009
In this paper, we propose a new notion called Certificate-Based Sequential Aggregate Signature. Certificate-based cryptography proposed by Gentry [8] combines the merit of traditional public key cryptography and identity based cryptography, without use of the costly certificate chain verification process and the removal of key escrow security concern ...

A structured aggregate signature scheme

2010 International Symposium On Information Theory & Its Applications, 2010
In multisignature scheme, verifiying the signing order is sometimes very important. A multisignature scheme in which generated signatures reflect the structure of signers, e.g. signing order, is called structured multisignature scheme and many such schemes have been proposed so far.
