ELECTRONIC DEVICE AND METHOD FOR ENCRYPTING AND DECRYPTING DATA

摘要

A data encrypting and decrypting method which functions in an electronic device is activated when an application program is activated in the device. Data arising from user input is generated and a public and private key pair is also generated. The data is encrypted with the public key to obtain cryptographs and the cryptographs are sent to the application program. The method allows for decryption of the cryptographs with the private key to obtain the original data.

主权项

1. An electronic device comprising:
a display device configured to display at least one user interface of an application program; an input device configured to detect user input on the user interface and generate corresponding data; at least one processor; a non-transitory storage device coupled to the at least one processor and storing one or more programs, which when executed by the at least one processor, cause the at least one processor to: generate a key pair comprising a public key and an associated private key; encrypt the data with the public key to obtain cryptographs; send the cryptographs to the application program; and decrypt the cryptographs with the private key to obtain the original data.
