Abstract
A wireless communication device, computer program product and method of establishing secure communications between a first wireless communication device and a second wireless communication device for an instant messaging application is provided. Contact information representing a contact associated with a second wireless communication device is received at the first device. The contact information includes capability information. The first device determines from the capability information whether the second device is capable of communicating using an enhanced encryption scheme, and if so, establishes a protected communication session by sending a pass phrase to the second device via an out of band channel and receiving the pass phrase back from the second device via the instant messaging application. Communication between the devices is performed using an enhanced encryption scheme.
