Specifically, risk is ubiquitous, it is especially rich in creative and challenge system integration industry, in the project implementation
Process risk is still worth manager to pay much attention to.Compared with traditional industries, System Integration Project has multi-crossed disciplines, wealth
Power, intelligence-intensive feature, so that more " uncertain factors " is brought, if manager lacks calm planning and is likely to
Lead to the failure of target.For this purpose, the moment keeps the sense of risk of System Integration Project management, unite with Probability and mathematics
The tools such as meter go risk present in research project progress, find the good plan controlled risk.
Project risk feature in the combining information system integration is refined as following several classes: i.e. conceptual design risk, equipment choosing
Type risk, new-old system risk of handover, loss of data risk, network security risk, project process risk, institutional framework risk
Deng.For the above Risk characteristics, planning replying risk is worked out actively to change or reduce the probability or hazard analysis and HACCP of risk generation,
And identified risk is reinforced monitoring, stage by stage, incrementally lower the risk damage in project management.
On the basis of a upper embodiment, the distribution that the access limit distribution module is written and read permission includes following step
It is rapid:
Step 1: carrying out the distribution of read right, comprising:
Step 1.1: by cost management end, time management end, construction management end, data safety library management end, management data
When needing to carry out write-in data, block catenary system functional module, which sends to count at random, needs that data are written for library and risk management end
End node, random number use the end node public key encryption, which generates new block, and passes through the Hash of a upper block
Value, this block theme, random number and timestamp generate verifying cryptographic Hash h；
Step 1.2: newly-generated block and verifying cryptographic Hash h are sent block catenary system functional module, h by the end node
Using the public key encryption of block catenary system functional module, block catenary system functional module verification verifying cryptographic Hash h, and by new area
Block chain and data signature are broadcast to block chain network；
Step 1.3: when end node is autonomously generated new block in violation of rules and regulations, because of random number and timestamp difference, therefore verifying Hash
Value h1 is different, and block catenary system functional module is responsible for the validity of verification verifying cryptographic Hash；If verifying cryptographic Hash is invalid breathe out
Uncommon value, then determine that newly-generated block chain is invalid；
Step 2: carrying out the distribution of write permission, comprising:
Step 2.1: the content of each end node write area block in block chain is held exclusive symmetrical using end node
Key encryption, exclusive symmetric key are stored in USB-key, and the content of block body is retrieved using this block theme；When it
When his shareholder's end node needs access region block content, need to hold the USB-key for being stored with the exclusive symmetric key,
The content of block body could be decrypted；
Step 2.2: center end node according to engineering construction process analysis end node it should be appreciated that block chain content, i.e.,
The read right of end node realizes point of read right according to read right to end node USB-key of the distribution comprising exclusive symmetric key
Match.
