Abstract
A secure operating environment for a telecommunication device is disclosed, where a trusted execution environment (TEE) can establish both first secure communication (SC) channel between the TEE and a security-enabled SIM card, and a second SC between a service provider entity and Trustlet application, which is a component of the TEE of the telecommunication device. The telecommunication device may include a processor(s), an identification module, and a memory including the TEE and a normal operating environment (NOE). The TEE can be operated by the one or more processors to establish the first SC channel, authenticate a service identifier of the identification module, and establish the second SC channel, prior to an execution of the NOE.
