Abstract:

By taking ideas of identity-based cryptography into incremental signatures, the concept of identity-based incremental signature was proposed, and then a specific scheme from lattices was also constructed.The scheme was shown to be provably secure against adaptive chosen identity and chosen message attacks in the standard model, assuming the hardness of the small integer solution problem.Theoretical analysis and experimental results show that the computational overhead of the incremental signature algorithm is less than that of the standard signature algorithm.

Key words: incremental signature, identity-based cryptography, lattice, standard model, small integer solution problem
