MULTI-AGENT identity combined key Signature authentication PROTOCOL based schnorr signature with provable security under AVISPA
International Journal of Advanced Trends in Computer Science and Engineering · 2020
In recent years, Mobile agent technology has been significantly used in different domain applications.Yet because of its strong mobility via network caring its code and data, the agent technology faces some security issues as verifying the integrity and authenticity of information carried by the agent or its code while its migration over the network.therefore, we propose as an alternative solution as a protocol for agent authentication security by adopting a new Identity combined distributed key-based schnorr signature inspired from the secure ID-based signature scheme and the schnorr signature, which could be applied to the agent technology as well to any distributed architecture technology thus to validate its authentication as a digital transaction which is an alternative for certificate-based proxy signatures to grant its data integrity, authentication and non-repudiation in digital communications.The scheme security overall based on the hardness assumption of solving the discrete log problem (DLP).We show through security analysis that our protocol is secure against possible attacks.Furthermore, through the formal security analysis using the AVISPA tool, we justify that our protocol is also secure against passive and active attacks.
