地理标记语言的分组密码算法加密

Key encryption technology of GML based on AES

针对地理标记语言面向数据、可理解性等特点带来的信息安全隐患,该文从安全性的角度对地理标记语言文档加密进行分析,进而提出了一种地理标记语言文档的加密与签名相结合的安全加密方案,以解决地理标记语言文档在描述、存储以及传输过程中的安全问题。该方案首先使用密钥分发协议将密钥分发给通信双方,然后使用高级加密标准算法对文档加密,同时使用RSA算法对文档进行数字签名,进而实现地理标记语言文档高安全性加密。最后,对该方案进行安全性测试,结果表明该方案具有较好的安全性能和实现效率。

According to the fact that the characteristic of geography markup language（GML）such as data-oriented will bring the problem of information security, this paper put forward a new safety encrypt solution for GML document based on advanced encryption standard（AES）through analyzing GML structure from the aspect of security. This solution used both encryption and digital signature to solve the security problem of GML in the course of transmission. First, it distributed the key to both sides of communication using key distribution protocol. And then encrypted the GML documents using AES algorithm. At the same time distributed the digital signature for documents using RSA algorithm. Finally, this paper tested the security of this solution. The results showed that the solution was more efficient and safe.
