The Ssl Protocol And Remote Medical Monitoring Applications

The With the computer technology and information technology development, information is becoming more networked, people demand the quality of information is continuous improvement in the security of information is also increasingly being attention. SSL protocol as the transmission of secure and reliable end to end de facto standard has been vigorously development. At the same time as the medical information is becoming more and also put forward higher requirements for security, in the long-distance medical monitoring system, embedded devices and hospital data centers to ensure the communication security has become a key point of patient data security. SSL on an effective solution to this problem.This article first introduces the basic theory of information security technology, mainly related to the encryption method, message validation, authentication of the message digest algorithms and digital signatures the principles and methods. With the above, following the analysis of the basis of the principles and mechanisms of SSL, which provides a number of cryptographic techniques for user authentication, data encryption, transmission, data integrity verification, data signing, and other functions, is the user's data security, integrity in the Internet transmission. Respectively, using the open source project OpenSSL, MatrixSSL as computer terminals and embedded-end SSL implementations to realize a dynamic link library and the SSL protocol with X.509 digital certificates issued by the CA system functions, and SSL protocols and by Dynamic Link Library CA system issued X.509 digital certificates used in long-distance medical care system, terminals and data center communications, the Internet-based SSL protocol to achieve the security of medical data transmission and communication of both authentication.The system mainly uses data encryption; identity authentication technology to ensure data security, integrity and data transfer pairs put the legitimacy of the identity verification and non-repudiation. The terminal by the medical equipment data acquisition and data transmission parts, in order to improve the data acquisition speed and reduced the load on embedded devices on the DES encryption algorithm can be simplified to meet the requirements at the same time not affect the performance of embedded systems, in data collection in the process of data compression and encryption. Then uses C / S mode of secure data transmission tunnel for transmission. This will not only ensure the collection of data security and security of user information can also ensure that the entire system performance.
