New Intel chips ensure better security
The next generation of Intel Corp. microprocessors for cell phones and handheld computers will, for the first time, include hard-wired security features that can enforce copy protection and help prevent hackers from wreaking havoc on wireless networks.
Intel's PXA27x processors, announced Monday at a conference in Taiwan, contain a security "engine" that's on the same piece of silicon but separated from the area where general processing takes place. The engine also has access to secure memory.
Today, security tasks such as handling the keys that unscramble data are typically processed like any other task. As a result, it's possible that an errant program can alter, intercept or damage jobs that are supposed to be secure.
