Securing Software Updates for Automobiles

Uptane is an open and secure software update system design which protects software delivered over-the-air to the computerized units of automobiles. The framework can thwart attacks from malicious actors who can compromise servers and networks used to sign and deliver updates. Hence, it is designed to be resilient even to the best efforts of nation state attackers. There are multiple different free open source and closed source implementations available. Uptane is integrated into Automotive Grade Linux, an open source system currently used by many large OEMs, and has also been adopted by a number of U.S. and international manufacturers. Within the next few years, about one-third of new cars on U.S. roads will include Uptane.

Currently considered the de facto secure standard for software updates on automobiles, in July 2018, formal standardization of Uptane began under a non-profit consortium called the Uptane Alliance. Uptane Standard for Design and Implementation version 1.0, which presents procedures for secure design and implementation of the framework, was released on July 31, 2019, under the auspices of the IEEE/ISTO Federation. The initiative now continues as a Linux Foundation Joint Development Foundation project, with versions 1.1.0 and 1.2.0 released in 2021. Recommended deployment strategies are under active development, and are published and regularly updated on this site. All Uptane materials, including technical papers, security audits, and a public reference implementation are also freely available for all to use without a fee.
