Abstract: In this paper, a new two-party key agreement protocol is proposed, which adopts a compact structure to ensure the anonymity of the scheme. In this paper, the security of the new scheme is analyzed by the provable security theory, and the anonymity and AKE security of the scheme are proven. The new scheme has a shorter message length and requires only two rounds of interaction, with significant performance advantages over similar schemes.

Key words: key exchange, compact structure, anonymity, provable security, authenticity

摘要: 提出了一种新的双方密钥协商协议,新方案采用紧致结构以确保方案的匿名性。之后利用可证明安全理论对新方案进行了严格的安全性分析,同时对方案的匿名性和AKE安全性进行了论证。新方案的消息长度较短,且只需两轮交互,与类似方案相比有较明显的性能优势。
