- Abstract
- The present invention relates to a subscriber station security-related parameter negotiation method in a wireless portable Internet system. The subscriber station security-related parameter negotiation method includes security-related parameters in transmitting/receiving basic capability negotiation request messages and basic capability negotiation response messages such that the subscriber station and the base station negotiate the subscriber station security-related parameters. The security-related parameters include an authorization policy support subfield used to negotiate an authorization policy between the subscriber station and the base station, and message authentication code mode subfields used to negotiate a message authentication code mode. The base station can inform the subscriber station that authentication or message authentication is not performed and is omitted according to a service provider policy by writing it on the authorization policy support subfield or message authentication code mode subfield. In addition, the subscriber station and the base station can select an authorization policy formed with at least one combination through the authorization policy support subfield of the security negotiation parameters. According to the present invention, the service provider of the wireless portable Internet system can more efficiently and flexibly manage the system by providing a scheme for omitting an authentication function and a message authentication function as well as for supporting various authorization policies and message authentication functions.
