    Abstract: PROBLEM TO BE SOLVED: To provide a flexible setting method for a shared counter by sharing a counter with a tree structure between a plurality of security modules while suppressing the amount of secure memory usage. SOLUTION: The shared counter is achieved by making a node with a tree structure of a first counter group and a node with a tree structure of a second counter group shared between the first counter group with a tree structure managed by a first secure module and the second counter group with a tree structure managed by a second secure module. A sharing method by a tree structure flexibly makes an addition, elimination and access restriction setting of a module that uses the shared counter. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract translation: 要解决的问题：通过在抑制安全存储器使用量的同时在多个安全模块之间共享具有树结构的计数器来为共享计数器提供灵活的设置方法。 解决方案：共享计数器是通过使具有第一计数器组的树结构的节点和具有第二计数器组的树结构的节点在第一计数器组之间共享的树结构与由第一计数器组管理的树结构 模块和具有由第二安全模块管理的树结构的第二计数器组。 通过树结构的共享方法灵活地使用使用共享计数器的模块的添加，消除和访问限制设置。 版权所有（C）2009，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To prevent illegal action such as replacing information terminal software with a group of old modules if software is composed of a group of modules provided by more than one provider. SOLUTION: An information terminal includes: a first information processing section configured by executing a group of information processing modules of a first provider; a second information processing section configured by executing a group of information processing modules of a second provider; and a security module. The security module includes: a cumulating section for calculating a summarized cumulative value of a software module and storing the value in a register; a counter for holding a counter value indicating the version of the software module; and a configuration authentication section for authenticating the configuration of the software module. The first information processing section verifies configuration authentication data generated by the configuration authentication section and controls the activation of a software module in the group of information processing modules of the second provider.

    Abstract: PROBLEM TO BE SOLVED: To provide a computing technology capable of securely correcting one rule element of complicated authentication rules in a reliable environment.SOLUTION: A security LSI with tamper resistance includes a nonvolatile memory, a volatile memory, a monotone counter region, a configuration register storing storage information related to a platform status, and an encryption section. The security LSI also includes an object rule correction ticket issue part that corrects a rule included in an object received from the outside. Only when the received object includes the same encryption hash as a stored encryption hash, the ticket issue part is activated. Therefore, a rule correction is performed by a method for which origin of the correction can be sufficiently checked.

    Abstract translation: 要解决的问题：提供一种能够在可靠环境中安全地校正复杂认证规则的一个规则要素的计算技术。 解决方案：具有防篡改性的安全LSI包括非易失性存储器，易失性存储器，单调计数器区域，存储与平台状态相关的存储信息的配置寄存器和加密部件。 安全LSI还包括对象规则校正单发行部，其对从外部接收到的对象中包含的规则进行校正。 只有当接收到的对象包含与存储的加密散列相同的加密散列时，才能激活票证发行部分。 因此，通过可以充分检查校正的原点的方法来执行规则校正。 版权所有（C）2012，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To update certificates without making a customized set of updated certificates for each machine even if the machine has optional components. SOLUTION: The server 118 makes a set of updated certificates including all candidate pieces of software which can be activated in the device. A mobile device 110 receives the set from the server 118, and searches updated certificates corresponding to pieces of software which are being activated in the device 110.
