商用数据安全传输模型的研究与扩展

Research and expansion of commercial model used in data transmission

数据在网络中的安全传输需要解决数据的保密性、完整性、身份认证与不可否认性。讨论并扩展了一种商用的数据安全传输模型,采取软硬件结合方法,利用PKI理论和智能卡结合,使得模型结构简单,灵活,又具有很高的安全性,从而可以保证商用数据在不可信网络中得以安全的传输。本方案是可行的,高效的,安全的。

Data transferred through network have to solve confidentiality, authentication, integrity and non-repudiation. A secure data transferred model was researched and some useful expansion with both software and hardware was given out. This scheme has advantages such as simple and flexible and high security based on PKI and smart cards. So this scheme could ensure the data security in insecure net. As above, the scheme proposed is feasible and efficient with high security.
