    摘要: A license managing device sets a security area for storing a license file, maintains the security area as an encoded file in an inactive state of the security area by encoding the security area, maintains the security area as a directory in an active state of the security area by decoding the security area, and encodes a license file by using a file encoding key according to the user's request and stores the same in a security area in an active state of the security area.

    摘要: A group signature system includes: a key issuer server for generating a first parameter of a group public key, generating a corresponding master issuing key, and issuing a signature key to a user when a user device joins; an opener server for generating a second parameter of the group public key, and a corresponding master opening key and master linking key; and a linker server for checking whether two valid signatures have been linked by using the master linking key when the two signatures corresponding to a group public key are given. The group signature system further includes: a signature verifying unit for confirming a validity of the given signatures and a signer information confirming unit for confirming a validity of singer confirming information generated by the opener server.

    摘要: There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.
