20120311001 | SMARTCARD FILE SYSTEM AND FILE SELECTION METHOD THEREOF - The invention provides a Smartcard file system and its method for selecting file. Said file system, including MF as well as a variety of DFs and Efs in the MF, wherein application root directory (ADF) is added in the MF; the tile attributes of said ADF, DF and EF of the tile system include the Application Identifier (AID); when visiting with HTTP protocol, the AID is understood as a long file name. External entities accessing said file system with the HTTP protocol, namely locating the application and file managed with CWS via URL; in URL, AID of directory or file identities its long file name, so that Smartcard file system also can support long file system and the way of selecting file of URL, which makes Smartcard to support the WEB services easier and more accepted by the user. | 12-06-2012 |
20130001304 | PAYMENT SYSTEM AND METHOD OF IC CARD AND A MULTI-APPLICATION IC CARD AS WELL AS A PAYMENT TERMINAL - A payment system and method of IC card and a multi-application IC card as well as payment terminal are proposed in the present invention. The terminal and the IC card perform off-line data authentication using an asymmetric key algorithm during an off-line transaction, and if the transaction is not approved in manner of off-line, the terminal and the IC card performs an on-line transaction via a host. Therefore, the payment system and method of IC card and the multi-application IC card as well as payment terminal disclosed in the present invention can be used both in machinery without on-line transaction environment and in standard merchant machinery with on-line transaction environment. | 01-03-2013 |
20130290718 | MOBILE STORAGE DEVICE AND THE DATA PROCESSING SYSTEM AND METHOD BASED THEREON - The present invention relates to network security technology, and particularly relates to a mobile storage device for data processing in security, and a data processing system comprising the mobile storage device, and a data processing method using the data processing system. According to the present invention, the mobile storage device for data processing in security comprising: at least one memory for storing a secret key; an interface circuit; and a processing unit for communicating with a remote device via the interface circuit and performing security processing and application processing, the security processing including data encryption and decryption with the secret key. Compared with the prior art, the mobile storage device according to the embodiments of the present invention stores not only confidential information such as secret key and digital certificate but also applications for executing transaction processes, whereby providing security protection for the applications at the same level as the confidential information. In addition, where the mobile storage device has a capability of simulating a network interface, a client terminal, such as a personal computer, previously used for executing the applications now can function as a bridge connector between the mobile storage device and a remote server, and the packeting and unpacketing of the transaction data can be performed inside the mobile storage device. This greatly improves the security performance of the transaction processes. | 10-31-2013 |
