Description
Technical field
The present invention relates to a kind of anti-counterfeiting method and systems of credible performing environment user interface, suitable for holding with credible
The mobile terminal device of row environment belongs to mobile platform trust computing field.
Background technique
With universal and mobile platform business the prosperity of smart machine, safety problem also becomes terminal user and service mentions
For one of quotient's focus of attention.The security risks such as application program generally existing at present is cracked, private data is stolen, to a
Even country of people, enterprise all causes great threat.And the credible performing environment based on chip and equipment safety can be to answer
With higher safety guarantee is provided, the safe practice of mobile platform mainstream in the market was become already.
Credible performing environment (Trusted Execution Environment, abbreviation TEE), is one on processor
Safety zone, it can be ensured that the confidentiality and integrity of its code loaded and data.Relative to common performing environment (Rich
Execution Environment, abbreviation REE) for, credible performing environment possesses higher security level；And relative to peace
For full element (Security Element, abbreviation SE), the advantage of credible performing environment is then that cost is lower.
TEE realizes the security isolation with REE from hardware layer to application layer.High level operating system (Rich OS, also referred to as
Rich operating system) it operates in REE, and independent secure operating system (TEE OS) can be then carried in TEE.When an application needs
When calling the security service in TEE, first passes through TEE Driver and TEE OS and interact, then TEE OS will be handled
Device is set as safe mode and the security service that brings into operation.In the scene for needing to show data using user interface, TEE OS
Secure memory can be set by display memory region, refuse the access of REE, avoid the data in TEE from being leaked or distort with this.
However, the application operated in REE can forge the display interface of TEE, if user can not distinguish the interface of forgery,
The private datas such as password are had input in the interface of forgery, it will cause huge losses.
Summary of the invention
In view of the above problems, the purpose of the present invention is to provide a kind of anti-counterfeiting methods of credible performing environment user interface
And system, the authenticity of user's discrimination TEE user interface is helped using anti-counterfeiting mark code.
In order to achieve the above object, the present invention takes following technical scheme:
A kind of user interface anti-counterfeiting method of the credible performing environment of mobile terminal, comprising the following steps:
The communication server generates or setting anti-counterfeiting mark code；
