The Secure Enclave stands as a certified security stronghold nestled within a System-On-Chip design. It encompasses robust hardware and low-level software, forming an impenetrable defense against both hardware and software attacks. Within its secure confines, the Secure Enclave can adeptly accommodate Kigen SIM or eSIM OS and applications and their sensitive cryptographic data. This remarkable feature is also recognized as an integrated Tamper Resistant Element (iTRE).
