TrustZone, announced by ARM in May of last year, is a hardware-based security extension to the ARM RISC microprocessor architecture. The technology is said to tag and partition secure code and data within the system, and maintain a clear, hardware separation between secure and non-secure information.
According to Trusted Logic, the Security Module implements the TrustZone APIs in a manner that enables "smooth evolution and compatibility" with future versions of the software running on ARM TrustZone technology-enabled processors. The software is part of a portfolio of embedded security products offered by ARM and developed under a recently announced agreement between Trusted Logic and ARM.
The new software will protect against common attacks and frauds such as mobile phone security codes being overwritten, and will provide consumers with a secure environment for mobile banking, e-commerce, and digital rights management in mobile phones, payment terminals and set-top boxes, Trusted Logic says.
An evaluation version of the TrustZone-compatible Security Module is expected to become available from ARM in Q4 2004, with full release in Q1 2005.
