TrustZone technology strengthens AMD
AMD has announced that ARM TrustZone technology will be included in its future APUs.
As the two companies have agreed, AMD can produce x86 chips that can accommodate an ARM Cortex A5 processor. The TrustZone procedure is based on this dedicated core. A hardware-based security system provides two virtual processors, so a program can switch between two states (or worlds). Both worlds can operate independently using a kernel. The essence of the procedure is that information cannot be transferred from the protected world to the less reliable world, ie it is safe from malicious applications.
The Cortex A5 auxiliary core is practically for safety purposes only.
Application examples
- When paying online, we can securely provide our personal information.
- Digital rights management
- Protection against software attacks.
- It can also be used well in cloud-based technologies.
- e-Ticket system
AMD said the Cortex A5 auxiliary core will appear in some APUs as early as next year. Obviously, in 2014 there will be more such products on the market.
