Abstract: In cloud computing, we protect information system and huge amounts of data by the cryptographic techniques, each business application system needs large capacity and reliable cloud cryptographic service to protect information security and efficiently use cloud cryptography resources and effective key management. In this paper, we put forward a cryptography resource system to effectively manage cryptography resource in cloud computing environment. The system provides the whole life cycle of key and cryptographic device. Through hardware virtualization technology, the system can provide high speed, reliable, scalable cryptographic service for multiple application system. It effectively improves the utilization of cryptography resources and reduces the risk of the key management and application.

Key words: cloud computing, cloud security, cloud cryptography, cryptography resource system, key management
