KSE Security Chip

Security for Digital Transformation

The KSE series is a Security Chip certified by the NIS KCMVP program.

KSE Series

The KSE series runs the KCMVP-certified cryptographic module (CLIB V1.0) as firmware on top of a CC-certified security chip.

Cryptographic keys are stored securely in the Secure Memory inside the security chip. All cryptographic operations are performed internally, ensuring keys are never exposed outside the chip.

KSE300B includes built-in Anti-Tampering functionality to protect core weapons system technology.
