A “Best Current Practice” for 3GPP-based cellular system security
2014
This paper is an attempt at formulating a Best Current Practice (BCP) for access security and a baseline for core network security in the 3GPP-based systems. This encompasses the 2G circuit-switched GSM system, the 2.5G packet-switched GPRS system, the 3G UMTS system and the 4G LTE/LTE-A system. The 3GPP have defined several security standards, but many measures are optional and there are several areas deliberately not covered by the 3GPP standards. The present document is therefore an attempt at pointing out the best available options and providing advice on how to achieve an overall system hardening, which is badly needed as the cellular systems have undoubtedly become one of the most cri…
GPRS Security for Smart Meters
2013
Part 1: Cross-Domain Conference and Workshop on Multidisciplinary Research and Practice for Information Systems (CD-ARES 2013); International audience; Many Smart Grid installations rely on General Packet Radio Service (GPRS) for wireless communication in Advanced Metering Infrastructures (AMI). In this paper we describe security functions available in GPRS, explaining authentication and encryption options, and evaluate how suitable it is for use in a Smart Grid environment. We conclude that suitability of GPRS depends on the chosen authentication and encryption functions, and on selecting a reliable and trustworthy mobile network operator.
