communication device, service seeker method, service provider method, and computer program product

摘要

The present invention relates to a secure wireless communication system having a communication device acting as a service seeker (210) and an additional communication device acting as a service provider (220) according to a security protocol that defines link layer security according to a security mechanism. The service provider enables a first service that requires link layer security according to a first security mechanism. the devices establish a first secure link connection (241) to enable the first service. The service provider determines that an additional service requires link layer security in accordance with a second security mechanism other than the first security mechanism. the devices now establish a second secure link connection (242) at the link layer according to the second security mechanism while the first secure link connection remains active to enable additional service via the second secure link connection, while blocking the service seeker from accessing the additional service until the second secure link connection has been established.
