Abstract


Secret sharing has a very important role in key management , an emerging technology with the deepening and expansion of the global information technology , network-based secret sharing ; the face of ever-changing network technology to build relying on distributed systems secret sharing to become the current hot topics . Faced with the increasing amount of key , realistic multi - secret sharing scheme it is natural pursuit of the goal . To solve the above problem , we design a network - based threshold key sharing technology . Secret sharing in asynchronous distributed network , it is necessary to give full play to the distributed network in the message delivered concurrently with the critical section access , access advantage . In this regard is mainly achieved the following results: ( 1) Based on Elliptic Curve Cryptography security and TCP port , establish the asynchronous verifiable multi- secret sharing model of AVMKS and the key refresh protocol . In addition, the recovery phase , based on the solution of algebraic equations , a different method of Lagrange polynomial interpolation and NIST digital signature system , improve the efficiency of the implementation of the model . (2) based on threshold multi - secret sharing scheme , designed an alternative electronic voting scheme for large-scale elections ; allows the system there is more than one scrutineer ( institutions ) . Even in votes generation , encryption , transmission and decryption , statistical process adaptive adversary , does not affect the normal conduct of the election . (3) Based on XTR, designed an alternative threshold multi - secret sharing model member of authentication methods . When the anti - extortion for electronic money , its implementation success rate than ordinary PIN program one of the six .
