Study Of The SSL Protocol Based On Bank Self-service Terminal

In order to solve the security problem of the banking self-service terminals transmit data on the network. This paper presents the Public Key Infrastructure which is based on the formation and development of public key encryption technology, the public key infrastructure security system is used to protect the banking self-service framework. The most part of the core of Public Key Infrastructure is the digital certificate authentication center system which is used to release a variety of digital certificates and certificate revocation lists and so on. It presents the services including: application for the certificate, approval for the certificate, certificate update, certificate revocation and so on.This paper design and implement the digital certificate authentication system on the banking self-service terminals, the system is based on the openssl open source toolbox. The system's main function is to generate the IIS server certificates of the banking self-service terminals which ensure that banks can only be visited by users who have the client certificate. It can generate the client certificates which make the users visit the banking self-service terminals monitor system, X509certificates are generated the pkcs12 certificates which can be installed easy. It can generate a list of abolition of the certificate and so on. Digital certificate authentication system is combined with the banking self-service terminal monitoring system which enhances the security of the banking self-service terminal.In this paper, the use of openssl open source toolkit, design and realization of a digital certificate authentication system which provides the main functions of the IIS certificate, client-side digital certificate and the making of the PKCS12 certificate and so on. It provides the authentication, data encryption and security management services, and the digital certificate authentication system combines the self-service terminal system monitoring system project.
