Abstract

A system and method for providing a secure environment for mobile telephones and other devices are disclosed. The system and method may utilize trust zoning, layered memory, and a secure matrix model having, for example, a memory protection module for protecting memory; a secure debug module for ensuring security of the debug module; a secure file system module for protecting the secure file system; and a trusted time source module for protecting components. Embodiments of the present invention may protect against security attacks on a variety of hardware and software components while permitting suitable levels of accessibility for developmental and maintenance purposes.

Description

technical field [0001] In general, the present invention relates to mobile devices, such as mobile phones. More particularly, the present invention relates to security systems and methods for mobile devices and other communication devices. Background technique [0002] Current technology provides for communication between multiple devices via various communication media. For example, computers routinely communicate via the Internet. Mobile devices, such as mobile telephones and personal digital assistants (PDAs), are used to communicate with various devices via wireless, analog, digital, and other means. For example, mobile devices can be used to communicate with other mobile units, computer systems and networks, analog telephone systems, and other devices. [0003] The connectivity and functionality of mobile devices provide a vast space for multimedia and multi-function applications. For example, mobile phones are commonly used to: communicate with other mobile (wirele...
