Abstract:
In the last few years, the traditonal certificate-based setting is replaced by the ID-based setting. Proxy signatures allow the delegation of signing rights from an original user to its proxy agent. Normally, the original signer can authorize a group of proxy agents to sign any document on its behalf. Currently in our study, we have proposed an ID-based multi-proxy signature scheme, from bilinear pairings based on â€˜k-plus problemâ€™. We document that the proposed scheme is secure under the inverse computational Die-Hellman (INV-CDH) assumption. Besides, we have proven that the new scheme is computationally more efficient and takes less running time than other existing schemes [5, 10]. Our proposed method meets all the security requirements of a proxy signature scheme proposed by Lee
