数字签名技术的应用

摘要

Digital signature technology is used on the basis of public key cryptosystem, which can examine whether data has been distorted in transmission process and its authenticity and integrity. By using the security guarantee mechanism provided by the technology, we realized the security encryption for transaction message in transmission in horizontal network established by a city, thus improving the security of the system from software framework.%数字签名技术建立在公钥加密系统基础之上，可以检验数据传输过程中是否被篡改以及数据的真实性和完整性。利用其提供的安全保障机制，在某市自建的横向联网系统中实现了对交易报文在传递过程中的安全加密，从软件架构上进一步完善了系统的安全体系。
