Problems solved by technology

In the existing authorized encryption and decryption methods, the authorization process is relatively complicated, and the user often needs the authorizer to provide the decryption key to obtain the authorization
If the authorizer is not present, the user cannot obtain authorization and cannot perform data transmission
Moreover, there is a risk of forgetting and losing the key, which is inconvenient to use and poses a great security risk

Abstract

The invention relates to a data encryption and decryption method and system, a server, a storage device and a mobile device. The data encryption and decryption method comprises the steps: generating afirst ciphertext after directly building wireless connection with the storage device, transmitting the first ciphertext to the storage device, and receiving a second ciphertext transmitted by the storage device; sending the first feature information to a storage device, and receiving second feature information sent by the storage device; decrypting the second feature information by using the second ciphertext, and performing feature matching on the decrypted second feature information; if the feature matching succeeds, sending a key to the storage device to enable the storage device to execute corresponding encryption and decryption operations; and receiving and storing the encryption and decryption state sent by the storage device. Thus, bidirectional authentication before data transmission is realized, the security of data transmission is further guaranteed, an authorizer does not need to independently provide a key, the key does not need to be worried about being forgotten and lost, and the implementation is convenient and rapid.

Description

technical field [0001] The present application relates to the technical field of data encryption and decryption, and in particular to a data encryption and decryption method and system, a server, a storage device, and a mobile device. Background technique [0002] Nowadays, mobile communication is moving towards the wireless interconnection of all things, and the wireless rate is getting higher and higher. For example, wireless earphones for mobile phones and wireless charging technology are popular. These are short-distance wireless technologies. Although the application scenarios are different, they are realized. The leap from wired to wireless. With the development of wireless communication technology, it is becoming more and more common to use wireless communication technology to realize data interaction. [0003] In related technologies, using wireless communication technology to realize data interaction has the advantages of low learning cost and easy implementation. ...
