The invention discloses a
system and method for initializing a safety indicator of a credible
user interface, and relates to the field of mobile intelligent terminals. The
system comprises a TSM
server, an application store and a mobile intelligent terminal. The mobile intelligent terminal comprises a mobile intelligent terminal
operating system and a TEE. The mobile intelligent terminal
operating system comprises a
client side
application module and a TEE
client side drive module. The TEE provides a
safe operation environment isolated from the mobile intelligent terminal
operating system, the interior of the TEE is logically divided into a plurality of safety domains, and mutual isolation and independence of credible applications are guaranteed. Each safety domain is provided with a safety domain management module and a credible
application module, and the TEE provides the
safe operation environment for the safety domain management modules and the credible application modules. According to the
system and method, individualization of the safety indicator in the credible UI provided for the credible application modules can be safely achieved, display credibility of the safety indicator is effectively improved, and the risk that the safety indicator is attacked and intercepted by malicious
software is reduced.
