Embodiment Construction
[0045] The present invention will be further described below with reference to the accompanying drawings and specific examples.
[0046] The new type of bidding and decryption method based on the national SM2 algorithm based on the embodiment, including the electronic bidding bidding border encryption process and the electronic bidding bidding branch decryption process, specifically:
[0047] The electronic bidding bidding border encryption process:
[0048] Step 1, the user uses the preformed cloud encryption platform public key certificate to the bidding file D A T A encryption, generate P c _e N c (D a t a);
[0049] Step 2, the user uses the tool to call the user USB Key to issue a digital envelope for the bidding file of the encrypted country, generate Pk C s 7 (P c -E N c (D A T a));
[0050] Step 3: Upload Digital Envelope P K C S 7 (p c -E N c (D A T A)) to the bidding platform;
[0051] Step 4, bidding the bidding platform Pk C s 7 (P c -E N c (D A T A)) Sends to the clou...
