SAGE Activity Report 2009

Chairman: Steve Babbage (Vodafone)

Responsible for specifying cryptographic algorithms for telecommunications standards.

The Security Algorithms Group of Experts (SAGE) continues to respond to the needs of other committees for cryptographic algorithms. The Group specifies cryptographic algorithms for use in standardised telecommunications systems. In recent years most of its work has been for mobile telephone standards – the Global System for Mobile Communication (GSM™), General Packet Radio Service (GPRS), the Universal Mobile Telecommunications System (UMTS™) and increasingly LTE™, the radio technology beyond 3G which is being specified by the Third Generation Partnership Project (3GPP™). Additional work is undertaken for Terrestrial Trunked Radio (TETRA) and Digital Enhanced Cordless Telecommunications (DECT™).

SAGE began work on 2009 on a third algorithm set produced by 3GPP, which has been proposed by 3GPP’s Chinese partners to meet the requirements of their country’s regulatory authorities. SAGE has been evaluating the algorithm to make sure that it meets all requirements of high strength and sufficiently low complexity, and expects to make recommendations as to its suitability by mid-2010.

The Group also revised the set of algorithms produced in 2008 for DECT to accommodate a longer – and safer – cipher key.
