Method and system for running encrypted files

摘要

A computer-implemented method for running an encrypted file and system are provided, where the method includes the following steps: receiving a file running instruction; invoking an encrypted target file according to the file running instruction, and performing memory-based decryption on the encrypted target file according to key information corresponding to the encrypted target file; and running the encrypted target file on which the memory-based decryption is performed.

1. A computer-implemented method for running an encrypted file, comprising:
at a computer having one or more processors and memory for storing programs to be executed by the one or more processors:
receiving an identity authentication instruction, the identity authentication instruction including a user identifier and a password;identifying a set of encrypted target files associated with the user identifier after the identity authentication succeeds, each encrypted target file having corresponding key information that is machine-generated for the user identifier and unknown to any end user;receiving a file running instruction associated with one of the encrypted target files;invoking the encrypted target file according to the file running instruction, the invoking further including retrieving key information corresponding to the encrypted target file, performing decryption on the encrypted target file in the memory according to the key information, and storing the decrypted target file in the memory;running the decrypted target file on which the decryption is performed;receiving a file closing instruction associated with the decrypted target file;performing encryption on the decrypted target file in the memory according to the key information; anddeleting the decrypted target file from the memory.
