摘要： A radio frequency system and a password management method applied to a storage device of the radio frequency system are provided, in which a first access password is stored for deciding whether to permit access to information and a first changed password. The first changed password, a second access password, and a second changed password are received, and the first access password is changed to the second access password, and the first changed password is changed to the second changed password. Accordingly, information access authority in the storage device and a password change authority can be exclusively transferred according to the transfer of management of the storage device, and information leakage caused by a previous manager's password leakage or a third person's password leakage can be prevented.

摘要： Provided are a method of managing data in a network system and a network system using the method. The method includes substituting a master password for a predetermined function to generate a password; if a password for requesting an access to specific data is input, checking whether the input password matches with the generated password; and if the input password matches with the generated password, allowing the access to the specific data. Thus, in a case where a storage unit makes access levels of data into multilayered access levels to authenticate a password, the storage unit can store only a password to efficiently authenticate and manage an access to data.

摘要： A security method using an electronic signature, which improves the performance of an electronic signature authentication by generating and verifying an electronic signature using a mediator, and acquires a forward security in an electronic signature generation and verification by adding a forward secure signature of semi-trusted party (SEM) to a partial signature value generated based on a secret key piece of the SEM. A public key and an optional secret key composed of two kinds of pieces are generated by a certificate authority in response to a request from a user terminal device. The secret key pieces are issued to the user terminal device and a semi-trusted party not to be overlapped with each other. A first signature piece generated from the issued pieces of the private key is transmitted to the user terminal device from the semi-trusted party when a certificate of the user terminal device is still valid.

摘要： A user key allocation method for broadcast encryption is provided. The user key allocation method includes generating a plurality of subsets by dividing one group including a plurality of nodes to sub-groups and allocating key sets with respect to the subsets, respectively. The nodes included in the subset may be odd nodes and even nodes of the nodes of the group. The nodes are arranged so that privileged nodes are consecutive or there is only one privileged node. Accordingly, it is possible to reduce the data size transmitted from the server to the nodes by constituting one or more subsets from the nodes consecutively arranged and providing key sets with respect to the subsets.
