An Efficient Provable Security Identity-based Proxy Aggregate Signature Scheme

Lei Guo, Defa Hu


Under the hypothesis of the difficult problem that calculates the Diffie-Hellman, we construct an identity-based proxy aggregate signature scheme. The scheme not only satisfies all kinds of the security requirements of proxy signature, but also has the advantages of aggregate signature. Finally, we prove the correctness of the scheme strictly by using bilinear pairings technique, and give a detailed proof for the security of the scheme, the results show that the scheme is verifiable safe and reliable, and it is a safe and efficient scheme.

Disclaimer/Regarding indexing issue:

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
