基于安全策略的分布式农产品数字认证

Distributed digital authentication of agricultural products based on security policy

为了提高农产品数字认证系统的安全性,把农业信息化与密码学技术结合起来,采用RSA-TBOS签密方案,保证分布节点与认证中心之间数据的保密性和认证性.分析与实验结果表明,系统在加入完整的安全模块后,在保证速度和效率不明显降低的前提下,提高了系统的可用性与安全性.

In order to improve the security of agricultural products of digital authentication system, the agricultural information technology combined with cryptography is used, via the application of RSATBOS signcryption, to ensure the confidentiality and authentication of data between the distributed nodes and the certification center. Analysis and experimental results show that this system with additional perfect security function can enhance its security and availability without obvious reduction of speed and efficiency.
