Terminal data transmission processing method and terminal

Abstract

The invention is applicable to the field of communication technologies, and provides a method for processing the data transmission of terminals. The method comprises the following steps of: receiving a data transmission command; judging whether a terminal has physical feature data; if the terminal has the physical feature data, receiving an input check code; if the terminal does not have the physical feature data, after the physical feature data is acquired, receiving the input check code; carrying out encryption processing on the data through the check code and the physical feature data; and sending the data subjected to encryption to a server. The invention also provides a terminal for implementing the method. Therefore, according to the invention, the data is encrypted through a special private key, thereby ensuring the security of data transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a terminal data transmission processing method and a terminal. Background technique [0002] With the development of communication technology, the application of various cloud services has become very common. Many end users encrypt and store important information through cloud servers for subsequent use. Existing encryption / decryption usually uses private key encryption, that is, both parties sending and receiving data must use the same key to encrypt and decrypt plaintext. For the requirement of symmetric encryption, the sender and the receiver must obtain a copy of the secret key in a safe way, and the security of the key must be guaranteed. If someone discovers the key and knows the algorithm, all communications using that key will be readable. [0003] The current common symmetric encryption algorithm generates an encryption or decryption key through t...

Problems solved by technology

This existing solution has obvious security risks. Since the key is stored on the server, the operator may obtain the key. If the key is obtained, the user's data may be decrypted, resulting in user information leakage.

At the same time, since the key needs to be transmitted between the terminal and the server, there is a security risk of key leakage during the transmission process

[0004] In summary, the existing encryption transmission technology of terminal data obviously has inconvenience and defects in actual use, so it is necessary to improve it
