It will be appreciated that the office automation approving person of enterprise would generally be copending to what is received based on office system
Application content carries out examination & approval processing, but a scene corresponding with security risk of the existing technology is: assuming that " application section
Point " A, which transmits pending application a content T, node B to " approval node " B, will apply the result of content T examination & approval (assuming that not having
Have and pass through examination & approval) node A is fed back to, since content T belongs to the classified papers (e.g. a contract) of company, it would be possible that meeting
Deposit this hidden danger: node B examination & approval by later by the approval results of content T feed back to node A this during, hacker enters
It invades that content T intercept and steals, then the approval results of content T are fed back to node A by hacker " approval node " B that disguises oneself as
(practical examination & approval not over, but hacker claims T that examination & approval pass through), such node A will have " misunderstanding ", and entire company
Not know and is hacked this meeting thing of visitor's invasion, subsequent work can make mistakes again and again, meanwhile, the confidential content T of company is also known by hacker
Dawn.
Therefore, hacker attacks system disguises oneself as " approval node " in order to prevent, the office automation of the enterprise of the present embodiment

Node A is fed back to, this process may be by hacker's intrusion system due to " approval results are fed back to node A by node B "
The case where occur, it is possible to there is the case where hacker disguises oneself as node B to node A feedback information, therefore node B also needs to add
Close code key s is sent to " intelligent contract node " as code key s` to be verified, so that " intelligent contract node " executes following step
S40 carries out secondary encrypted authentication.
Step S40: the intelligence contract node is encrypted by application content described in the secret key pair to be verified with life
At abstract to be verified, the abstract to be verified is compared with the original digest, comparison result is sent to the application
Node, so that the application node is handled the approval results according to the comparison result.
In the concrete realization, the cryptographic digest is construed as an identification information of " approval node ".
It will be appreciated that code key s` to be verified is passed to " intelligent contract node " by node B, utilized by " intelligent contract node "
Code key s` to be verified carries out secondary encryption to application content T, if obtained abstract to be verified is exactly that T` (obtains to be verified pluck
Will be as the cryptographic digest T` stored in the block of block catenary system), then prove that approval node B is not pretended by hacker, because
It is unique for cryptographic digest T` here.
The embodiment of the present invention encryption key s can only be encrypted, and can not be decrypted, and " intelligent contract node " is to application content
T carries out secondary encryption, if the first time cryptographic digest that the cryptographic digest and block catenary system that obtain after encrypting for second save
Equally, then prove that approval node B is not pretended illegally by hacker.
Further, the step of abstract to be verified is compared the intelligent contract node with the original digest
