公钥密码学,主要研究和设计具有如下特性的公钥密码算法与协议:
公钥加密算法(Public-Key Encryption)、数字签名算法(Digital Signature)、功能加密算法(Functional Encryption)、密钥协商协议(Key Exchange);
可抵抗新型密码分析和攻击技术,包括密钥泄露攻击(Leakage Attacks)、依赖密钥消息攻击(Key-Dependent Message Attacks)、相关密钥攻击(Related-Key Attacks)、选择打开攻击(Selective-Opening Attacks)等;
可证明安全,且安全性可紧致地规约到离散对数、格相关等问题的困难性假设上。
