New electronic evidence authentication and protection scheme based on lattice

The electronic evidence authentication and protection scheme is based on the lattice cryptosystem, and other illegal users or attackers are unable to obtain the original electronic evidence data in the whole process of the electronic evidence protection system, which well protects the security of the original electronic evidence and increases the overall security of the scheme.

本电子证据认证与保护方案基于格密码体制（lattice cryptosystem）构建。在该电子证据保护系统的全流程中，非法用户与攻击者均无法获取原始电子证据数据，可有效保障原始电子证据的安全性，提升该方案的整体安全性能。
