Embodiment 1

[0030] figure 1 It is a flow chart of the method for safe interaction of online engineering quotation according to an embodiment of the present invention. like figure 1 As shown, this implementation provides a secure interaction method for online engineering quotation, including:

[0031] S101: Obtain a first hash value of the plaintext of the online engineering quotation to be encrypted, and obtain a second hash value according to the first hash value; the online engineering quotation includes bidder information, quotation data information, quotation items, and quotations recipient information, etc.

[0032] S102, use the first hash value and the second hash value to generate a plaintext secret key to encrypt the plaintext of the online project quotation to obtain a first ciphertext; and calculate a third hash value of the first ciphertext; can use The DES algorithm, the 3DES algorithm or the AES algorithm obtains the first ciphertext; and calculates the third hash value o...

Embodiment 2

[0044] This embodiment provides an online engineering quotation security interactive system, such as figure 2 As shown, the system includes a first acquisition unit 201 , a first encryption unit 202 , a second encryption unit 203 , a first decryption unit 204 and a second decryption unit 205 .

[0045] The system includes:

[0046] The first obtaining unit 201: obtains the first hash value of the plaintext of the online project quotation, and obtains the second hash value according to the first hash value;

[0047] The first encryption unit 202: encrypts the plaintext of the online project quotation by using the plaintext key generated by the first hash value and the second hash value to obtain the first ciphertext; and calculates the third hash of the first ciphertext. Greek value;

[0048] The second encryption unit 203: encrypt the first ciphertext with the first secret key to obtain the second ciphertext; encrypt the third hash value with the second secret key to obtain...

Embodiment 3

[0059] This embodiment provides an electronic device, including a memory, a processor, and a computer program stored in the memory and running on the processor, when the processor executes the computer program, the online process described in Embodiment 1 is implemented Steps of a secure interaction method for engineering quotations.

Abstract

The invention provides an online engineering quotation safety interaction method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining a first hash value of a to-be-sent online project quotation plaintext, obtaining a second hash value by using the first hash value, encrypting the to-be-sent online project quotation plaintext according to a plaintext secret key generated by the first hash value and the second hash value to obtain a first ciphertext, and sending the first ciphertext to the to-be-sent online project quotation plaintext, and encrypting the first ciphertext by using a first key to obtain a second ciphertext, encrypting a third hash value generated according to the first ciphertext by using a second key to generate a third ciphertext, sending the second ciphertext and the third ciphertext to a receiver, and sending the first hash value to the receiver through quantum communication. According to the invention, the difference of plaintext and secret keys used for each online project quotation is utilized, and the quantum communication technology is utilized to transmit and generate the first hash value of the plaintext and secret keys, so that compared with a traditional scheme of encrypting by utilizing a fixed secret key, the security of the online project quotation is effectively improved.

Description

technical field [0001] The present invention relates to the field of online engineering quotation, and more particularly, to an online engineering quotation security interaction method, system, electronic device and storage medium. Background technique [0002] At present, with the maturity of Internet technology, various network-based application services have developed rapidly. The online engineering quotation system came into being, but the current online engineering quotation system has certain security risks, which is mainly reflected in the lack of attention to the security of online engineering quotations. Generally, only the online engineering quotation is encrypted or digitally signed, and the security measures are not enough. Ideally, there is a possibility that online engineering quotations may be tampered with or stolen, causing great security risks. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, according to one aspect of the present ...
