IBM has developed a new microprocessor encryption technology to protect users’ data.
IBM plans to announce the availability of its Secure Blue solution this week, and has already developed one of its own PowerPC chips bundled with the new technology.
Secure Blue can be used on any chip, including those from Intel and AMD, and can be used to protect data on PCs, personal digital assistants, mobile phones and digital music players.
When Secure Blue is used, data is encrypted and decrypted as it runs through a processor, and remains encrypted in the device’s RAM memory. The data is generally only readable when it is actually displayed on the device.
Such a solution could help to protect users from remote attackers when web-enabled systems have been breached or when devices have been stolen.
A small number of circuits have to be added to a processor to allow Secure Blue to work, although IBM maintains the solution does not slow down the processor.
