Intel unveils processor with hard-wired 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.
With Intel's new chips, cell phone makers and carriers can guarantee a greater, hardware-based level of security for customers who use the devices to access corporate networks or need to lock down information.
Carriers, for instance, can secure the software that boots up a phone, making it next to impossible for hackers to tweak the device and cause trouble.
"Carriers want to be able to identify the handset on the network. They want to make sure nobody is doing anything malicious with that handset," said Dave Rogers, Intel's wireless marketing manager.
