远程心电信号的加密设计

The Design of Encryption of Remote ECG Signal

心电信号对心血管疾病的远程诊断、远程分析和远程治疗具有很重要的作用,但是心电信号在网络传输过程中会遭到数据毁坏、替换、盗窃和丢失。因此,本文采用端到端加密和DES(数据加密标准)算法对心电信号进行加密和解密,使密文的每一位都依赖于明文和密钥的每一位,保证了心电信号在通信网中传输的安全性和可靠性,具有很强的保密强度,能受住时间的检验和攻击。

ECG signals are of great importance for the remote diagnosis,analysis and treatment of Cardiovascular disease.However,some ECG signals may be destroyed,replaced,stolen or even lost in the process of internet transmission.Therefore,this paper aims to introduce the method of DES to encode and discoed the ECG signals.This method completely disorders the messages of the text,every code corresponds with its particular text and password.These all confirm the safety and reliability of ECG signals in the process of transmission and this method has stood the test of time.
