Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to figure 1 and figure 2 , a method for sending commercial secrets based on data encryption technology, comprising the following steps:

[0029]1) Set the parties A and B who need to transmit commercial secrets, and negotiate and set the key required for data transmission between A and B according to the asymmetric DH algorithm;

[0030] 2) Assume that Party A is the data sender and Party B is the data receiver. In addition, the positions of both parties can be interchanged. To construct the key between Party A and Party B, first agree on two public prime numbers p and g. To obtain a 128-bit For the key, set p as a larger prime number with a length of 128bit, and set g as a smaller prime number, which is combined into a random number interval [g,p];

[0031] 3) Party A and Party B randomly generate two 128-bit numbers a and b from the interval [g,p], a...

Abstract

A method of sending commercial secrets based on data encryption technology. Firstly, for further secure sending of commercial secrets, the DH algorithm is used to enable both parties to send commercial secrets to obtain the same local key. In this process, the outside world can only obtain the public key, but not the public key. The private keys of both parties and the local key are cracked, which provides a first-level protection for information transmission; secondly, the two sides of the information transmission set their own plaintext encoding and sorting schemes, and set up a second-level protection; finally, the local key is used in the AES encryption algorithm. Based on the encryption of the new plaintext code, three-level protection is set to realize the secure encrypted transmission of data between the two parties of commercial information transmission; at the same time, the AES encryption algorithm is extremely efficient in the encrypted transmission of data, providing real-time and effective encryption of ciphertext information. Delivery is guaranteed. The invention provides a safe and efficient multi-algorithm combination, and a method for sending commercial secrets based on data encryption technology with self-defined encryption schemes of both communication parties.

Description

technical field [0001] The invention relates to the fields of data information processing, e-commerce, encrypted data transmission, and computer applications, in particular to a method for sending commercial secrets based on data encryption technology. Background technique [0002] With the rapid development of the current e-commerce field, the transmission and execution of commercial information plays a particularly important role in promoting the normal operation and rapid development of business. Therefore, the safe sending and receiving of commercial confidential information is of great importance to commercial operating units in all walks of life. Saying matters. However, with the rapid development of the field of computer technology, the channels of commercial data information transmission are diverse, and while we are gaining its benefits, there are also huge disadvantages. Some commercial criminals use network information channels to illegally steal commercial secre...
