Cross-Domain Authentication and Data Transmission Scheme Based on the Symmetric Cryptosystem

目的结合跨域用户身份认证和跨域加密数据传输,设计基于对称密码体制的跨域身份认证和数据传输方案.方法构造的协议模型包含初次认证传输协议和后续认证传输协议两个部分.两个部分可以分别在不同的场景下工作,并且具有不同的使用效果:初次认证协议全面可靠,后续认证协议简单高效.结果认证过程结束后,就可以安全地进行数据传输了.该方案中的身份认证和数据加密过程均采用对称加密算法加密,可以有效地保障数据的机密性和完整性,同时具有较高的处理效率.结论性能分析和安全性分析表明,该协议简单、快速、实用,具有较高的性能和安全性,可以应用在多种网络环境中.

Combined with cross-domain user authentication and encrypted data transmission, a cross-domain authentication and data transmission scheme is proposed in this paper. The scheme includes initial authentication transmission protocol and subsequent authentication transmission pro- tocol. The two protocols can be operated under different scenarios and have different used effects. The former is more comprehensive and reliable, and the latter is more simple and efficient. Results show that after the authentication process, the data can be safely transported. The authentication and transmission processes in the scheme are encrypted by the symmetric cryptosystem, which can ensure confidentiality and integrity of data and have more efficient processing. Conclusion is that the proposed scheme is simple, fast, practical and has high performance and security. It can be applied in different network environments.
