Webray Satellite Key Mgmt Center

The Satellite Key Management Center (卫星密钥管理中心) is a component of Webray's satellite communication encryption system, which also includes a configuration management center, central station crypto machines, and small station crypto machines, along with embedded cryptographic modules for satellite terminals, unmanned equipment, and mobile terminals. The Satellite Key Management Center is responsible for providing centralized key management, distribution, and network access authentication services for cryptographic devices (crypto machines and crypto cards) across a satellite communication network. It automatically generates and updates cryptographic keys for the entire network. Core functions: - Unified Key Management: Manages the full lifecycle of working keys for all network crypto machines and crypto cards, covering key generation, update, archiving, and destruction. - Key Distribution: Distributes keys to crypto machines and crypto cards via unicast and multicast methods, with security protections applied during the distribution process. - Network Access Authentication: Authenticates the identity of crypto machines and crypto cards upon network entry to verify that cryptographic modules are genuine and trusted, preventing spoofed base stations or terminals from accessing the satellite network. - Chinese Cryptographic Algorithms: Supports the SM2, SM3, and SM4 national cryptographic algorithms to address data authenticity, integrity, confidentiality, and non-repudiation. The system supports grouping of crypto machines and keys to define access boundaries within encrypted networks, enabling flexible permission configuration without changing network topology. It is designed for satellite internet environments covering communication satellites, ground central stations, terminal small stations, vehicle-mounted, ship-borne, airborne unmanned equipment, mobile terminals, and IoT devices.
