Following on from last week’s article about security and cryptography, this week we have a new product from CPU Tech. As the name might suggest, CPU Tech designs CPU chips. The twist is, this company’s chips have a high level of security built into them. As you also might guess, one of their big customers is your government.

CPU Tech starts with the familiar PowerPC processor architecture, so if you’re in the market for PowerPC chips, CPU Tech is worth a look for that reason alone. But the real excitement comes when you enable the on-chip security features. The processor is tamper- and virus- and hacker-resistant, and it includes all sorts of other features I’m not allowed to talk about.
