Good information about trusting devices

A decade ago, software products were much maligned for buggy code and a poor security. Then Bill Gates vowed to make "trustworthy computing" the company's highest priority.
The phone or tablet you purchased is yours. It does not belong to the carrier that you bought it from despite the fact that the device is emblazoned with its corporate identity, logo or splash screen. This outright ownership you have in the device means that you can do whatever you like with it once you've walked out of the store, assuming you don't mess with the radio hardware and cause interference to your fellow users
Trusted Computing is a technology developed and promoted by the Trusted Computing Group. The term is taken from the field of trusted systems and has a specialized meaning. With Trusted Computing, the computer will consistently behave in expected ways, and those behaviors will be enforced by hardware and software. In practice, Trusted Computing uses cryptography to help enforce a selected behavior. The main functionality of TC is to allow someone else to verify that only authorized code runs on a system. This authorization covers initial booting and kernel and may also cover applications and various scripts. Just by itself TC does not protect against attacks that exploit security vulnerabilities introduced by programming bugs.
Trusted Computing proponents such as IDC the Enterprise Strategy Group and Endpoint Technologies Associates claim the technology will make computers safer, less prone to viruses and malware, and thus more reliable from an end-user perspective. In addition, they also claim that Trusted Computing will allow computers and servers to offer improved security over that which is currently available. Opponents often claim this technology will be used primarily to enforce digital rights management policies and not to increase computer security.
