Certicateless Aggregate Short Signature Scheme

Jayaprakash Kar

Abstract

An aggregate signature scheme is the aggregation of multiple signatures into a single compact signature of short string that can convince to any arbitrary verifier participating in the scheme. The aggregate signature scheme is very useful for real-world cryptographic applications such as secure routing, database outsourcing, etc. where the signatures on several distinct messages generated by many distinct users requires to be compact. In this paper, we presented an aggregate signature scheme using Certificateless Public Key Cryptography(CL-PKC). The scheme is provably secure with strongest security and shortest length. We have proven the scheme is existentially unforgeable under adaptive chosen message attack, assuming the hardness of computational Diffie-Hellman(CDH) Problem.
