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

The invention provides a data encryption technology-based trade secret sending method. Firstly, for the further secure sending of trade secrets, two trade secret sending parties are made to acquire the same local key by using a DH algorithm, the outside only can acquire a public key and cannot acquire private keys of the two parties or crack the local key in the process, and therefore first-levelprotection is provided for information sending; secondly, the two information sending parties set their own plaintext code sorting schemes, and second-level protection is set; finally, new plaintext code are encrypted on the basis of an AES encryption algorithm by utilizing the local key, and third-level protection is set, and then secure encryption transmission of data between the two trade information transmission parties is achieved; and meanwhile the AES encryption algorithm is extremely efficient on the data encryption transmission aspect and provides a guarantee for real-time and efficient transmission of ciphertext information. The secure and efficient multiple algorithm-combined data encryption technology-based trade secret sending method in which the two communication parties customize the encryption scheme is provided.

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...
