Despite its imperfections, GSM security has stood well the test of time. In part, this security success has relied on closed platforms that prevent the end-user from tampering with the GSM protocol stacks. While it is possible to build phones that do not have such restrictions, this is difficult due to, e.g., legislation and technical complexity. Unlicensed Mobile Access (UMA) is a new technology that provides access to GSM services over Wireless LAN or Bluetooth. This paper examines the security implications of UMA for GSM security, focusing especially on the impact of open terminal platforms.
