Specific embodiment
In order to make it easy to understand, being illustrated first to concept involved in the embodiment of the present invention:
Digital signature:
As shown in fig. 7, being illustrated so that digest algorithm is hash algorithm as an example here, Fig. 7 is the signature in digital signature
With the process schematic of solution signature verification.
Digital signature is the integrated use to asymmetric encryption techniques and digital digest technology, and transmitting terminal utilizes digest algorithm
(such as hash algorithm) can be generated the corresponding informative abstract of original text, and be made a summary and be carried out to the communication information using the private key of transmitting terminal
Signature, is then transferred to receiving end for the signing messages after signature, receiving end use is identical with transmitting terminal together with original text
Hash algorithm adopts generation informative abstract 1 in a like fashion to the original text received, and decodes the label that are signed with using public key
Name information obtains informative abstract 2, will compare with above- mentioned information abstract 1 with informative abstract 2, and if identical, illustrate to receive
Terminating the original text received is completely, not distorted by third-party in transmission process, otherwise, illustrate original text by third
Fang Xiugai.Wherein, above-mentioned original text refers to the unencryption raw information that transmitting terminal needs to send to receiving end.
Wherein, it should be noted that above-mentioned private key with public key is obtained by rivest, shamir, adelman, that is to say, that private
Key and key are existing for pairing, specifically, in embodiments of the present invention, private key can be any character string, it schematically, can
To be one 256 random numbers as private key, and public key is then the corresponding public affairs of private key generated using rivest, shamir, adelman
Key, specifically herein without limitation.It is further to note that above-mentioned rivest, shamir, adelman can wrap in the embodiment of the present invention
It includes, but is not limited to ed25519 algorithm, RSA Algorithm, DSA algorithm, Diffie-Hellman and ECC algorithm, the specific present invention
Embodiment is also without limitation.
Thus, for each transmitting terminal, there is its distinctive private key, and be all pair in digital signature
External world's secrecy, and by the relevant information of private key signature, it can only be decoded by its corresponding public key.Therefore, private key
The identity of private key holder can be represented, the identity of private key owner can be verified by private key corresponding public key.
By digital signature, then it is able to confirm that Content of Communication is that message sending end is signed and sended over, because other equipment are palmed off
The not signature of message sending end, and different Content of Communication, summary info are multifarious, it, can also be really by digest algorithm
The integrality of Content of Communication is protected, if Content of Communication is tampered halfway, corresponding digital signature will also change.Cause
This, therefore digital signature is able to verify that the integrality of Content of Communication and the identity of transmitting terminal.
