摘　　要：基于RSA密码体制对秘钥托管方案进行了进一步的研究和优化实现——多素数RSA密码体制。该优化方案满足了对用户秘钥安全管理与司法部门调查取证之间的协调,有效的解决了"一次监听,永久监听"问题,而且每个托管代理能够验证他所托管的子密钥的有效性,实现分布式托管的优化,规避了"阈下攻击"和托管部门权力滥用等问题。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 attack＂ and abuse of power by the hosting department.
