Since network and Internet develop, demand and regard about electron security field are increasing steadily. With this, effort to develop various encryption description is continued. So, today, utilization extent of encryption technology is widening continuously. Specially, though electronic commerce and electron signature technology through internet rose, PKI(Public Key Infrastructure) is one of technologies.
PKI brought several kind of new standards in encryption base technology. Such situation is continued in this moment. In spite of several kind of standardizations consist lively, shortcoming of solutions that apply PKI is expensive and slow. If main interest of encryption technology including PKI is the fast speed and security that improve, this is very serious problem. The various kinds alternatives about these problem are presented. But, we must consider about replace expense and stability etc. still. So, I propose that use suitable encryption policy by method to solve such problem. I improved some problems of existent PKI structure.
Subject of this treatise designs and embody communication component could use easily and simply short message communication or simplicity way encryption communication.
