Abstract

The embodiment of the invention discloses a user data encryption method and device. The method comprises the steps of acquiring user data to be encrypted, using a first secret key set for encrypting the user data to obtain the encrypted user data, using a second secret key set for encrypting secret keys in the first secret key set to obtain the encrypted first secret key set, updating the encrypted user data to a server to be stored, storing the encrypted first secret key set locally, and deleting the first secret key set. The user data encryption method and device are used, even though a hacker obtains the encrypted user data and the encrypted first secrete key set, the encrypted user data can not be decrypted through the encrypted first secrete key set to obtain original user data, the decryption difficulty of the user data is improved, and therefore the safety of the user data is improved.

Description

Technical field [0001] The invention relates to the field of computer security, in particular to a method and device for encrypting user data. Background technique [0002] With the development of the Internet, there are more and more data on user accounts and passwords on various shopping websites, social networks, mailboxes, etc. In order to prevent users’ data from being easily stolen and ensure data security, a reliable method Yes: Encrypt user data, and process the original plaintext data according to a certain encryption algorithm to make it a piece of code with no specific meaning. [0003] In the prior art, a commonly used data encryption method is to use a key to encrypt user data, upload the encrypted user data to a server, and save the key locally. [0004] However, the above-mentioned data encryption method has a problem: if the server is attacked by a hacker, the encrypted user data may be leaked, so that the user's original data may be cracked, and the security is low....
