Product Introduction

Overview of KMS, F70, and D51 devices with key specifications

The KMS - Private key generator

Device Purpose: Manage the root key for your communication domain, and generate a user private key for each VoLTE device within the domain based on the communication number.

Offline Design：All IP transmission channels (cellular/Wi-Fi) have been shut down at the system level.

SAKKE Key length: According to RFC 6508, the KMS root key length for SAKKE is 1024bit. The user private key length for SAKKE is 2048bit.

Root Key Secure Storage: KMS root key stored in KMS, the key used to encrypt the root key stored in U-key. U-key insertion is mandatory for KMS startup and operation.
