KSE by Keypair is a series of security chips certified by the National Intelligence Service's Korea Cryptographic Module Validation Program (KCMVP). It operates with a KCMVP-certified cryptographic module (CLIB V1.0) in firmware form on a Common Criteria (CC) certified security chip. The KSE series is designed for secure storage of cryptographic keys and performance of cryptographic operations within the chip, preventing external exposure of keys. It supports various applications including Crypto API and TLS/DTLS, communicating with host CPUs through I/O interfaces.
