Patent number: 7558963Abstract: The present invention provides a means for determining authenticity of a combination of files which are downloaded to a mobile station, and which are related to one another. To achieve the stated object, in a system according to the present invention, mobile station 16, which is capable of running a Java-APP, receives an ADF from CP server device 12. Then mobile station 16 receives a SDF from trusted server device 18, which is identified by data contained in the ADF. Mobile station 16 calculates a hash value of certificate data contained in the ADF, and verifies whether the calculated hash value of the certificate data and a hash value of the certificate data which is contained in the SDF are identical to each other. Next, mobile station 16 receives a JAR file from CP server device 12. Mobile station 16 calculates a hash value of the JAR file, and verifies whether the calculated hash value of the JAR file and a hash value of the JAR file contained in the ADF are identical to each other.Type: GrantFiled: March 31, 2004Date of Patent: July 7, 2009Assignee: NTT DoCoMo, Inc.Inventors: Naoki Naruse, Yuichi Ichikawa, Tatsuro Oi, Nobuyuki Watanabe, Yasunori Hattori, Masato Takeshita, Masakazu Nishida, Mao Asai, Masayuki Tsuda, Atsuki Tomioka, Kazuhiro Yamada, Satoshi Washio, Dai Kamiya, Naoki Yamane, Keiichi Murakami

Patent number: 7519687Abstract: A mobile telephone 2 having a function for downloading and executing an application A from a network server comprises a communications module execution control system 1. The judging section 132 acquires and refers to an attribute information file 14. If the attribute information file 14 contains a (UseTelephone=call) definition, then the judging section 132 judges that the call section 102 is to be executed by the application A, and if there is no UseTelephone key, then it judges that the call section 102 is not be executed by the application A. If the UseTelephone value is not “call”, then the judging section 132 judges that the download of the application A is not allowed. The control section 136 controls the download and execution of the application A, in accordance with the judgement from the judging section 132.Type: GrantFiled: December 5, 2002Date of Patent: April 14, 2009Assignee: NTT DoCoMo, Inc.Inventors: Masayuki Tsuda, Takefumi Naganuma, Hideyuki Nagasawa, Eriko Oseki, Fukiko Maeda, Nobuyuki Watanabe, Mao Asai, Takashi Kondo, Kazuhiro Yamada, Dai Kamiya

Publication number: 20080222036Abstract: A mobile terminal capable of causing the user side to grasp whether or not a credit settlement service stops with a simple operation is provided. In the mobile terminal 10, validation and invalidation of a storage area within an IC chip assigned to an issuer application corresponding to one issuer are switched based on switching instruction information received from an issuer terminal 20 managed by one issuer. Then, when the issuer application starts, there is displayed in a lump whether or not the respective issuer applications are available on a display part 16, based on state information indicating whether or not the respective storage areas are validated. Therefore, in the mobile terminal 10, even if plural issuer applications are stored, it is possible to cause the user side to grasp which kind of the credit settlement service stops, with a simple operation of only starting a management application.Type: ApplicationFiled: March 6, 2008Publication date: September 11, 2008Applicant: NTT DoCoMo, Inc.Inventors: Mao ASAI, Shingo Sugimoto, Naoki Naruse, Hisashi Yoshinaga, Kumiko Yamaguchi

Patent number: 7421577Abstract: The present invention provides a means for reflecting modifications made in a server to data with regard to a scope of rights, which are granted to an application program operable in a communication device such as a mobile station, on data stored in the communication device. To achieve the aim, in a system according to the present invention, Java-AP software is provided to a mobile station by transmitting an ADF, a SDF and a JAR file from servers to the mobile station in that order. The SDF is a file containing data indicating restrictions of behavior of a Java-AP in a mobile station. The SDF also contains data indicating a validity state of the SDF, namely ‘valid’ or ‘invalid’, which is managed by management server device 18. Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server device 18 and checks whether a SDF corresponding to the Java-APP is valid.Type: GrantFiled: March 31, 2004Date of Patent: September 2, 2008Assignee: NTT DoCoMo, Inc.Inventors: Yuichi Ichikawa, Naoki Naruse, Tatsuro Oi, Nobuyuki Watanabe, Yasunori Hattori, Masato Takeshita, Masakazu Nishida, Mao Asai, Masayuki Tsuda, Atsuki Tomioka, Kazuhiro Yamada, Dai Kamiya, Satoshi Washio, Naoki Yamane, Keiichi Murakami

Publication number: 20060177111Abstract: It is an object of the present invention to provide a communication device, a digital signature verification method, and a digital signature generation method, in which the memory usage efficiency is improved without confidential information required for the verification or generation of a signature being easily leaked to the outside. The Java application judges whether signature verification is required for the received signature target data. When judging that signature verification is required, the Java application outputs the received signature target data to the PKI of the platform. The PKI verifies the signature that has been added to the data output by the Java application and performs signature generation, and then notifies the Java application.Type: ApplicationFiled: January 12, 2006Publication date: August 10, 2006Applicant: NTT DoCoMo, Inc.Inventors: Eiji Yano, Makoto Hamatsu, Mao Asai
