ARM^® TrustZone is a System-on-Chip (SoC) security concept that can protect payment subsystems from unauthorized use by software and hardware. TrustZone enables a system designer to isolate security critical hardware from an open and flexible main system. When combined with a TrustZone enabled processor, a hardware isolated run-time environment dedicated to security critical services can use the same high performance processor core as its host OS. Through isolation of both software and hardware a secure subsystem can be more easily evaluated for security and gain a security certification for much lower cost. Attempting this with a full SoC and Rich OS would take a considerable amount of time and effort. It might never be achieved since SoCs become increasingly complex with multiple bus-masters and OS updates are a frequent occurrence.

SecurCore integrates a number of features to assist manufacturers in creating tamper resistant secure devices capable of defending against advanced laboratory attacks. SecurCore processor cores are typically integrated within SIM cards, PayTV conditional access systems and other smart card applications.
