!!! Overview
[{$pagename}] is a secure area on any device that ensures that sensitive [data] is stored, processed and protected in a [trusted|Trust] environment.
!! [Mobile Device]
Most [Mobile Device] specifications are driven by [GlobalPlatform].
[{$pagename}] ([TEE]) is a secure area that resides in the main processor of a smartphone or any mobile device and ensures that sensitive data is stored, processed and protected in a trusted environment.
[{$pagename}] is defined in the [Global Platform] [Specifications|http://www.globalplatform.org/specificationsdevice.asp|target='_blank'].
[{$pagename}]'s ability to offer safe execution of authorized security software, known as 'trusted applications', enables it to provide end-to-end security by enforcing protection, [Confidentiality], [Integrity] and data access rights.[1]
[{$pagename}] is an element within the [Mobile Security Framework] within a [Mobile Device].
[{$pagename}] consists of software and hardware which offers a level of protection against software attacks, generated in the Rich [Operating System] environment.
[{$pagename}] assists in the control of access rights and houses sensitive applications, which need to be isolated from the Rich [Operating System].
For example, [{$pagename}] is the ideal environment for content providers offering a video for a limited period of time that need to keep their premium content (e.g. HD video) secure so that it cannot be shared for free.
* [TPM] ([Trusted Platform Module]) is a Piece of Hardware specifically created to do Crypto calculation with. It is physically isolated from the rest of the processing system and is almost always a separated IC on the mainboard to be so..
* [TEE] ([[{$pagename}]) is an area on a SOC that works like a [TPM], but is not physically isolated from the rest of the chip.
* [SE|Secure Element] ([Secure Element]) is a temper-resistant [secrets] store, much like a [Smart Card] or [SIM]-card. [SE|Secure Element] main purpose is to store [cryptographic] [secrets] in such a way that illicit use is hard or impossible to do. An example of this technology in major use is the [EMV] chip on payment cards.
When comparing the definitions that these 3 items are different, but share a common goal. The difference between a [TPM] and a [TEE] is mainly in how its implemented (purely Hardware or hard and software combo). The [Secure Element] has a different function that can be part of the function of a THM and/or a [TEE], by being a 'safe' place to store [cryptographic] [secrets].!! [Humor] on Terms
Is there ever a NOT [{$pagename}]?
Would anyone use an [Operating System] that was NOT [Trust]ed?!! More Information
There might be more information for this subject on one of the following:
