基于智能卡的分布式数据传输安全模型

针对分布式环境下的数据分发和管理问题，以智能卡与口令作为身份认证与密钥交换的基础，设计一个分布式数据传输安全模型。对该模型从敌手攻击角度和模型自身满足安全性角度进行安全性分析，结果表明，该模型不仅可以保证数据的完整性、不可否认性以及达成双方认证，还可以在最大程度上实现机密性信息在分布式环境下的安全传输过程。

Secure Model of Distributed Data Transmitting Based on Smart Card

To solve the problem of data distribution and management in the distributed environment, this paper proposes a secure communication model based on smart card and password authentication. The model is also analyzed from the point of view of adversary attacks and oneself security. Results show that the model not only guarantees the integrality, non-repudiation, and authentication, but also realizes the confidentiality during the data transmitting.
