History

Provides IMS media plane security for RTP based media which is designed to meet the following three main objectives: 1. to provide security for media usable across all access networks, 2. to provide an end-to-end (e2e) media security solution to satisfy major user categories, 3. to provide end-to-end (e2e) media security for important user groups like enterprises, National Security and Public Safety (NSPS) organizations and different government authorities who may have weaker trust in the inherent IMS security and/or may desire to provide their own key management service.
