Abstract

In the current iDEN system, it is desirable to add encryption to interconnect voice and circuit data services. Adding encryption over the air interface would be an obvious next step. Because of the architecture of the iDEN system, this encryption would probably be added from the subscriber unit to the Base Radio (BR). However, it would be desir- able to continue the encryption through the infra- structure as far as possible. This is not currently possible due to the logistics of session key distribu- tion to the Transcoder (XCDR), as well as handover issues for end-to-end encryption.
