The present disclosure provides a data processing method and apparatus, a computer device and a computer storage medium, wherein the method includes: performing blinding processing on target information to be transmitted to obtain blinded information; acquiring a plurality of pieces of first encryption information obtained by respectively performing encryption processing on the blinded information by a plurality of service participation ends; performing data fusion on the plurality of pieces of first encryption information to obtain second encryption information; and performing de-blinding processing on the second encryption information to obtain third encryption information as a ciphertext identification corresponding to the target information.

Data processing method and apparatus, computer device and computer storage medium

A system and method for providing cryptographic operation service in a virtualization environment. In the system, a configuration subsystem provides an interface for an administrator and a common user to input information about a virtual cryptographic device. A key file storage subsystem stores a key file and protects it with the protection password. A virtual machine operating subsystem obtains a corresponding key file from the storage subsystem according to the input of the configuration subsystem, creates a virtual device for a guest virtual machine, and finally operates the guest virtual machine to provide cryptographic computing service for the guest virtual machine. Thus the administrator/the common user can specify a key file and input a protection password for a guest virtual machine via the corresponding interface to facilitate the creation of a virtual cryptographic device, and can manage the virtual cryptographic device in a user-friendly and centralized manner. The guest virtual machine on a virtualization management platform can request for a secure cryptographic operation service, thereby alleviating the key security problem in virtualization environment.
