Abstract:

This paper conducted an in-depth study on provable security theory, sequential aggregate signature algorithms and aggregate signature technology. By improved the existing provably secure sequential aggregate signature algorithm based on the ISRSAC-PSS scheme, introduced a "block-type" concept and design a block sequential aggregate sig-nature algorithm based on ISRSAC-PSS. The analysis demonstrates that, under the hardness assumption of the large integer factorization problem, the proposed algorithm is provably secure in the random oracle model. Computational analysis reveals that with reasonable grouping strategies, the algorithm not only enhances efficiency but also reduces application overhead.
