面向电压监测终端的远程升级加密通讯方法

随着智能终端应用的日益增长和对其功能需求的不断提高,需要对嵌入式软件进行远程在应用升级。针对电压监测终端远程在线升级的安全性,从前的升级只考虑实现升级功能,而忽视升级效率和安全性,造成升级软件易被第三方窃取等问题,提出了一种在线升级加密通讯方法,通过对电压监测系统的架构、通讯规约、文件结构及加密方法等进行了分析和研究,采用断点续传、Fibonacci矩阵和Diffie-Hellman密钥交换等方法,既保证了升级操作的升级效率,又实现了安全性,容错性。实践结果表明,此种升级加密通讯方法,提高了终端的升级效率和安全。

Remote upgrading encryption communication method for voltage monitoring terminal

With the increasing application of intelligent terminal and the increasing demand for its functions, it is necessary to remotely upgrade IAP for embedded software. Aiming at the security of remote online upgrade of voltage monitoring terminal, the previous upgrade only considered the upgrade function, but neglected the efficiency and security of the upgrade, which made the upgrade software easy to be stolen by the third party. This paper proposed an online upgrade encryption communication method, through the framework of voltage monitoring system, communication protocol, files. The structure and encryption method are analyzed and studied. The methods of discontinuous transmission, Fibonacci matrix and Diffie-Hellman key exchange are used to ensure the efficiency of upgrade operation, and to achieve security and fault-tolerance. The practice results show that the upgraded encryption.
