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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure environment for subscriber device","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9591484","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
