Security Algorithms
Our Security Algorithms Group of Experts (SAGE) is
universally recognised for its work on authentication and
encryption mechanisms for different technologies. In
2016, SAGE developed new General Packet Radio Service
(GPRS) algorithms to support ‘Extended Coverage GSM’ (an
adaptation of 2G for more efficient service to the IoT). The
new algorithms (GEA5 for encryption, and GIA4 and GIA5 for
integrity protection) were delivered to the Third Generation
Partnership Project (3GPP™), with publication anticipated
early in 2017.

Quantum-Safe Cryptography
The emergence of the quantum computer will present a
serious challenge to current cryptographic techniques.
Previously secure encrypted information, including, for
example, bank account details, identity information and
military security, will become subject to discovery and
possible misuse. New ‘quantum-safe’ cryptographic
techniques have emerged in recent years that provide
protection against quantum threats. Our Industry
Specification Group (ISG) on Quantum-Safe Cryptography
(QSC) is assessing the current situation with regard to QSC
and developing specifications for the transition to quantum-
safe ICT applications.
In 2016, we completed our first Group Specification (GS)
which describes a quantum-safe algorithmic framework.
Good progress was also made on a Group Report (GR) which
will provide a quantum-safe threat and risk assessment for Other Aspects of Security

The ETSI Security Week
Now in its second year, the ETSI Security Week took place in June 2016 and attracted some 140 delegates. The
week consisted of a three-day IoT Security Workshop followed by an open plenary meeting of TC CYBER and the
Alliance for IoT Innovation (AIOTI) Security and Privacy Workshop.
