Abstract: The traditional encryption system can only realize single information sharing and can not guarantee the security of multiple information sharing.In order to solve this problem,network multi-server SIP information encryption system based on block chain and artificial intelligence was put forward and designed.Under the condition of network multi-server SIP,USB module is designed and a state register static switch is installed in the module to Judge the storage state of USB information,build information interface in the USB module,and use A/D converter for signal conversion,to provide basic information transmission signals for task dispatching.Add dispatching rules,divide the dispatched information into several data blocks.According to the lock box idea,use the function call function set to check the access rights,generate the authentication secret key,design the encryption execution module,according to the time sequence,combine the decomposed information into chain data structure in a certain order,to get the initial fingerprint by calculating the initial data matrix,specifically and secretly execute scheme according to the fingerprint design,and realize the information encryption through block chain and artificial intelligence technology.Experimental comparison results show that the system has high information transmission integrity and good encryption effect,and the reading and writing efficiency of the system is always maintained at 90% and above,which increases the reading and writing efficiency of information.
