CONCEALED MONITOR COMMUNICATIONS FROM A TASK IN A TRUSTED EXECUTION ENVIRONMENT

摘要

Concealed monitor communications from a task in a trusted execution environment (TEE) are disclosed. A first task executing in a first trusted execution environment (TEE) implemented on a processor device determines that a monitor communication is to be sent to a monitor task, the first task being configured to generate response messages in response to requests from requestor tasks, the response messages having a predetermined characteristic. The first task generates the monitor communication, the monitor communication having the predetermined characteristic and an encoded monitor communication report. The first task sends the monitor communication toward the monitor task.
