Proposal for secure group communication using encryption technology
In order to realize secure information sharing, it is common to encrypt information, using a common key called "Group Key" among group members. However, in the case of existing technologies, there is a concern that leakage of information occurs because contents of communications are preserved at the server, and also because the server administrator possesses the group key. Thus, in this Paper, we propose a method of using two kinds of random numbers of different generation origins sent through two different transmission routes in order to create a group key. With this method, group members can share the group key with security, and a secure group communication system with enhanced level of security can be realized.
