基于数据信息安全的手持掌机的设计

The design of handheld device based on data information security

为了解决主站和电能表之间的通信质量不稳定、数据传输的安全性相对较薄弱等问题,我们设计了一种用于智能电能表现场维护的具有加解密功能的手持设备。它功能完善,增加了安全单元,保证了手持设备的传输数据不被篡改、数据的机密性与完整性不被破坏,用户的身份不被冒用,适应电力用户用电信息采集系统全面高速发展的需要,具有广泛的应用前景。

In order to solve the unstable problem of communication quality and data transmission between power station and energy meter,we design a portable device with the functions of encryption and decryption used the field maintenance of intelligent electric meter.With the increased security,the data transmission is not tampered,confidentiality and data integrity is not destroyed,the identity information of the users is not disabused.It meets the need of the power system which can collect the power consumption information and has the widespread application prospect.
