Research on the Distributed Key Escrow Scheme Based on RSA
Zhiqi Mao · Electronic Science and Technology · 2015
Based on RSA cryptography system,this paper carries out a further research on and optimization of the secret key escrow scheme,called Multi-prime RSA Cryptosystem. This optimization scheme satisfies the coordination between the user secret key security management and the judicial department's investigation and evidence collection,effectively solving the problem of once monitoring,permanent monitoring. And each escrow agent can verify the validity of the sub-key it manages to realize the optimization of distributed hosting,and avoid such troubles as subliminal channel attackand abuse of power by the hosting department.
