Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To construct a secure network without installing a fire wall. SOLUTION: In S11, terminal equipment TE4 authenticates TE3. In S12, terminal equipment TE3 receiving the request inquires whether terminal equipment TE4 belongs to the same group or not from UNSP12 through a router 12. In S14, it is checked whether (ID: 3) and (ID: 4) are in the same group or not. They are decided to be in the same group and the result is transmitted to the router 12 through a bi-directional network 4 and a rout control part 22 from UNSP 2 and is transmitted to terminal equipment TE3 from the router 12. When they are in the same group, terminal authentication is realized (S15). In S16, terminal authentication between terminal equipment TE3 and TE4 is realized and security is established. When they are decided to be not in the same group, terminal authentication is not realized (S17), and security is not established in that case.
