摘要： PROBLEM TO BE SOLVED: To avoid the labor hours of removing a number of cables even in transportation of a file base station mounted with an external storage device together with a body. SOLUTION: The information processor includes the body 10 including a CPU, a keyboard 47, and a display device 78; the file base station 80 mounted with the external storage device such as an FD-D (flexible disk drive) 81 or a CD-ROM-D (CD-ROM drive) 83; and a port replicator 100 mounted with a number of connectors. The labor our of removing a number of cables connected to the port replicator 100 can be saved by removing, from the port replicator 100, only the body 10 or the body 10 and the file base station 80.

摘要： PROBLEM TO BE SOLVED: To reduce a time required for mutual authentication in a system in which mutual authentication is required among a plurality of devices. SOLUTION: A host device or a client device to be mutually authenticated is provided with a means for determining whether or not a session key held by each of them required in simple mutual authentication processing in which only a short a time is required for mutual authentication is valid for the other device which is trying to perform mutual authentication processing; and a means for transferring information required for achieving the means. The host device performs high speed simple mutual authentication processing when determined that the session key is valid, and perform normal mutual authentication processing in the other case. A client device performs simple mutual authentication processing when determined that the session key is valid, and replies an abnormal end to the host device without performing any simple mutual authentication processing in the other case. Thus, it is possible to more reduce the mean value of a time required for establishing the authentication state than a device in which this invention is not implemented. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了减少在多个设备之间需要相互认证的系统中相互认证所需的时间。解决方案：要相互认证的主机设备或客户端设备被提供有用于确定在简单的相互认证处理中需要的每个会话密钥所需的会话密钥是否需要短时间的装置，相互认证对于正在尝试执行相互认证处理的其他设备有效; 以及传达实现手段所需信息的手段。当确定会话密钥有效时，主机设备执行高速简单相互认证处理，并且在另一种情况下执行正常的相互认证处理。当确定会话密钥有效时，客户端设备执行简单的相互认证处理，并且在其他情况下不执行任何简单的相互认证处理，将异常结束复制到主机设备。因此，与不实施本发明的装置相比，可以进一步减少建立认证状态所需的时间的平均值。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the following problem: when a converted content is created by converting compression formats and the like of the content, an original content is deleted to prevent copyright infringement, and the original content cannot be restored from the converted content, the original content cannot be used again. SOLUTION: The original content and the converted content obtained by converting the original content are encoded with an identical content key. A license including the content key and conditions of use, such as a use period, is recorded in an access-limited area. When the converted content is used by an external storage medium, a copy of the original license is created, a period of use of the copy is changed into a period of use of the converted content designated by the user, and output to the external storage as a converted content license. At the same time, the period of use of the original content is rewritten so that it may not overlap the period of use defined by the conversion license. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that when using a conventional nonvolatile memory as a read cache or write cache, persistence of an effect as a cache is short due to its low rewriting resistance, an effect of improving speed is low due to its slow reading or writing speed, or a power saving effect is low due to a high power consumption when reading or writing.SOLUTION: A read cache and a write cache consist of two kinds of nonvolatile memories having characteristics different from each other, respectively. For example, a nonvolatile memory of high rewriting resistance is allocated to the write cache, while a nonvolatile memory of low rewriting resistance is allocated to the read cache, and the data management tables in the caches are stored in the nonvolatile memory of high rewriting resistance. Or, a nonvolatile memory of high write speed and low read speed is adopted for the write cache, and a nonvolatile memory of high read speed and low write speed is adopted for the read cache.
摘要翻译：要解决的问题为了解决当使用常规的非易失性存储器作为读取高速缓存或写入高速缓存时，由于其重写电阻低而作为高速缓存的效果的持续性很短，因此提高速度的效果低由于其读取或写入速度慢，或者由于读取或写入时的高功耗，节电效果较差。解决方案：读高速缓存和写缓存分别由具有彼此不同特性的两种非易失性存储器组成。例如，将高重写电阻的非易失性存储器分配给写入高速缓存，而将低重写电阻的非易失性存储器分配给读取的高速缓存，并且高速缓存中的数据管理表被存储在高重写电阻的非易失性存储器中。或者，写入高速缓存采用高写入速度和低读取速度的非易失性存储器，并且对于读取高速缓存采用高读取速度和低写入速度的非易失性存储器。版权所有（C）2012，JPO＆INPIT
