Abstract
A method includes storing a security credential associated with a communication network on a portable storage device. The method also includes detecting removal of the portable storage device from a specified location. The method further includes allowing at least one communication device to communicate over the communication network using the security credential. In addition, the method includes revoking the security credential after a specified time period has elapsed. The portable storage device could represent a card, and the specified location could represent a card reader/writer. Also, the communication network could represent a wireless network, and the security credential could represent a cryptographic key.
