Since the application mode of cryptography technology currently has different types in the cloud environment, a novel cryptography cloud framework was proposed, due to the non-expandability of cryptography resources. Through researching on the application models of the current encryption technology, the cryptography service demand under the cloud environment and the virtual structure of the cloud cryptography machine, this paper designed the framework of the cryptography cloud framework that provides cryptography services with the cloud computing mode. the design idea of the framework is expounded from two aspects include the function of modules and service flow of cryptography cloud, which resulted in the improvement of the flexibility of the application of cryptography technology in the cloud environment. Through the analysis of system function and management mode, it illustrated the availability and security of cryptography cloud framework. It was proved that cryptography cloud has the characteristics of high-availability in the implementation and experiment, and it can satisfy cryptography service demand in the cloud environment.
