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.
