Abstract


With the constant increase of social information , the network is a huge economic and social benefits , while also facing the increasingly serious security problem . Secret sharing is one of the important means of ensuring network security , it can be dispersed responsibility to enhance the security and robustness of the system . Traditional secret sharing mechanism , the secret is restored after become public information and can not be reused . However , in certain circumstances , such as the signature key required to complete a signature , the signature key can not be exposed , and for the next use . The paper first describes the generation of secret sharing and digital signature technology , development , and then explore secret sharing and threshold signature scheme . The secret of these programs can not be reused deficiencies , this paper proposes a secret without a trusted reusable (t, n) threshold signature scheme . The program has the following characteristics : ( 1 ) the scheme without a trusted group private key jointly decided by all members , members of the private key is generated by the members themselves , thereby enhancing the security of the system . ( 2 ) any t members on behalf of the groups signature . Members with its own private key to sign the message , and generate a partial signature ; t part signature synthesis to generate a threshold signature . (3) in the signing process , the members can be indirectly using the group private key , but not directly to restore the group private key , thus realizing the shared secret can be used repeatedly. Windows XP system , using VC 6.0 and Access of the program is to achieve a prototype system , and operator of large numbers of large prime numbers selection algorithm , Hash algorithm and the Galois domain Lagrange interpolation key algorithms involved in program implementation . Elaborate the design process and experimental results of the prototype system . The experimental results show that : this program is correct and feasible, to achieve a secret reusable .
