Methods and devices for establishing secure communication channels
A method of establishing a secure communication channel between a first communication device and a second communication device. The secure communication channel is defined by one or more algorithm options and the one or more algorithm options are associated with one of one or more option categories. The method includes receiving a signal representing one or more selections. The method further includes, for the respective option categories, generating a sorted list of algorithm options based on the received selections and generating a security association proposal including one or more of the algorithm options from the respective sorted lists of algorithm options. The security association proposal is generated based on an order in the sorted list of algorithm options. The method further includes transmitting the security association proposal to the second communication device for establishing the secure communication channel.
