Electricity metering password machine

The Electric Power Metering Cryptographic Machine is a new type of network communication cryptographic machine based on the host, specifically designed for the power system. It provides cryptographic services for electric power metering devices and ensures data encryption and protection for their integration into the power system.

Feature: Asymmetric: Supports the national encryption SM2 elliptic curve cryptography algorithm with a key length of 256 bits; supports RSA encryption algorithm.

Symmetric encryption: Supports national encryption algorithms SM1, SM4, SM6, as well as DES, 3DES, AES, AES192, AES256, etc.

Key Management: Utilizes a three-tier key management system, including master keys, key-protecting keys, and working keys. All keys are stored in the password card in encrypted form, ensuring secure key management.

Key Destruction: Supports destruction of SM2 key pairs, RSA key pairs, and communication keys, which cannot be recovered by any technical means after destruction.

Key Backup and Recovery: Supports backing up internal keys in encrypted form to external storage within the device, and employs a key-sharing mechanism to ensure the security of key backup. The backup keys can be restored to other encryption card devices of the same model.
