TrustZone technology provides a defense against malicious software attempting to tamper with critical data such as DRM counters. However, it does not prevent an offline rollback attack, which replaces selected current values in flash memory with previous values. Hence, additional protection is needed. This sidebar discusses a defense against rollback attacks that relies on TrustZone technology to provide both a logical partitioning of the flash for secure storage, and a secure execution environment for a special trusted software application.
Index Terms:
TrustZone technology, rollback attack, DRM counters, secure execution environment, trusted software application
