Encryption and decryption method and equipment for user resource

Abstract

The invention discloses an encryption method, a decryption method, encryption equipment and decryption equipment for a user resource. The encryption method comprises the steps of: acquiring the user resource to be processed, and determining a key index corresponding to secret keys used for encrypting the user resource; determining an encryption key used for encrypting the user resource according to the key index; and utilizing the encryption key to encrypt the user resource to obtain an encryption result. Through determining the key index for the user resource, and determining the encryption key used for encrypting the user resource according to the secret keys corresponding to the key index, the probability that the encryption keys determined by the system for different user resources are different is increased, further the problem that the risk of leakage of user information in an application platform is increased because an encryption method adopted for transmitting user information between application platforms between which a cooperative relationship is established is relatively fixed in the prior art can be effectively avoided, the security of the user resources is effectively improved, and the risk of leakage of the user resources is reduced.

Description

technical field [0001] The present application relates to the field of network information security, in particular to a method and device for encrypting and decrypting user resources. Background technique [0002] With the rapid development of Internet technology, various application platforms have emerged. In order to better provide users with network services, different application platforms can establish a cooperative relationship, and based on this cooperative relationship, part of the user information stored in one application platform can be used by other application platforms, effectively improving the application platform. The quality of network services provided to users. [0003] For example: Assuming that application platform A and application platform B have established a cooperative relationship, and application platform A and application platform B allow sharing of user address information, the user logs in to application platform B and initiates a purchase bu...
