Intra-Vehicle Information Security Framework

This paper presents an internal information security services framework for vehicular environments. The framework consists of a logical toolbox — a set of logical modules that are installed in a variety of embodiments (e.g., controllers) and which provide security functionality that vehicular applications require. The framework also includes several enablers, which are higher-level security functions that are integrated into vehicular applications. These enablers use the aforementioned tools to provide for many typical use-cases, such as secure logging, secure code update, and secure feature activation.

The Sorcerer’s Apprentice Guide to Fault Attacks

This paper covers the various methods that can be used to induce faults in semiconductors and exploit such errors maliciously. Several examples of attacks stemming from the exploiting of faults are explained. Finally a series of countermeasures to thwart these attacks are described.
