Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] Please refer to figure 1 , which shows a flowchart of an information processing method provided by an embodiment of the present invention. The information processing method is applicable to terminals used for information interaction in the network. Optionally, the terminal is an electronic device such as a mobile phone, a tablet computer, a desktop computer and a portable computer. The terminal can encrypt and decrypt information, and can also perform identity verification and digital signature.
[0042] Such as figure 1 As shown, the information processing method may include the following steps:
[0043] In step 101, the first terminal sends a primitive, a public key and key parameters to a second terminal.
[0044] The ke...

The invention discloses an information processing method, which belongs to the technical field of safety. The method includes receiving the primitive, public key, and key parameters sent by the first terminal; receiving an information encryption instruction, where the information encryption instruction is used to instruct to encrypt original information; and generating a random number according to the information encryption instruction; Encrypt the original information by using the random number, the primitive, the public key, and the key parameters to obtain encrypted auxiliary information and ciphertext; send the encrypted auxiliary information and the ciphertext to In the first terminal, the private key paired with the public key is stored in the first terminal; the problem that a key parameter with a relatively large length needs to be used in the current asymmetric encryption algorithm, resulting in a large amount of computation, is achieved, and the A key parameter with a shorter length can also ensure a good encryption effect, reduce the length of the selected key parameter, and reduce the calculation amount in the encryption process.
Description
technical field [0001] The embodiments of the present invention relate to the field of security technologies, and in particular, to an information processing method. Background technique [0002] With the rapid development of electronic information technology, more and more information is transmitted through the network. In order to ensure the security of information in network transmission, it is necessary to encrypt the information. The existing encryption algorithms include symmetric encryption algorithms and asymmetric encryption algorithms. . [0003] Symmetric encryption algorithm means that the sender and receiver of the information use the same encryption rule to encrypt and decrypt the information. Since the symmetric encryption algorithm requires the sender to inform the receiver of the encryption rules, storing and delivering the key has become the biggest problem affecting the effectiveness of encryption. In order to avoid passing the key directly, an asymmetri...
