Cryptanalysis of a certificateless aggregate signature scheme
public-key cryptography C4I
2016/12/26
Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries. In ...
Cryptanalysis and improvement of certificateless aggregate signature with conditional privacy-preserving for vehicular sensor networks
conditional privacy-preserving vehicular sensor networks
2016/7/15
Secure aggregate signature schemes have attracted more concern due to their wide application in resource constrained environment. Recently, Horng et al. [S. J. Horng et al., An efficient certificatele...
MQSAS - A Multivariate Sequential Aggregate Signature Scheme
Multivariate Cryptography HFEv- Sequential Aggregate Signatures
2016/5/24
(Sequential) Aggregate signature schemes enable a group of users u1,…,uk with messages m1,…,mk to produce a single signature Σ which states the integrity and authenticity of all the messages m1,…,mk. ...
Aggregate signature can combinensignatures on nmessages fromnusers into a single short signature, and the resulting signature can convince the verifier that thenusers indeed signed the ncorresponding ...
Efficient and Provably Secure Identity Based Aggregate Signature Schemes With Partial and Full Aggregation
Identity Based Signature Aggregate Signature Random Oracle Model Provable Security
2010/9/1
An identity based signature allows users to sign their documents using their private keys and the signature can be verified by any user by using the identity of the signer and public parameters of the...
Security Analysis of Aggregate signature and Batch verification signature schemes
Identity based signature aggregate signatures batch verification
2009/6/23
An identity based signature scheme allows any pair of users to communicate securely and
to verify each others signatures without exchanging public key certificates. An aggregate signature
scheme is ...
COMPARING TWO PAIRING-BASED AGGREGATE SIGNATURE SCHEMES
Pairing-Based Aggregate Signature Scheme elliptic curves Barreto-Naehrig
2009/6/11
In 2003, Boneh, Gentry, Lynn and Shacham (BGLS) devised the first provably-secure aggregate
signature scheme. Their scheme uses bilinear pairings and their security proof is in the random oracle mode...
