    • A writing data processing control apparatus includes an assignment part configured to assign processing of a plurality of pieces of writing data of predetermined divided writing regions, stored in a storage device, one by one to one of a plurality of processing apparatuses in which processing is performed in parallel, and a separation part configured, when a processing error occurred as a result of processing of writing data read from the storage device by a first processing apparatus assigned, to separate the first processing apparatus in which the processing error occurred from assigning targets of subsequent writing data processing, wherein the assignment part reassigns the processing of the writing data in which the processing error occurred to a second processing apparatus being different from the first processing apparatus.
    • 一种写入数据处理控制装置,包括一个分配部分,被配置为分配存储在存储装置中的预定划分的写入区域的多条写入数据的处理,所述多个处理装置执行处理 并行地配置有分离部,所述分离部被配置为当由分配的第一处理装置处理从所述存储装置读取的数据的处理时发生处理错误,以分离出发生了所述处理错误的所述第一处理装置, 随后的写入数据处理,其中所述分配部分将对所述处理错误发生的写入数据的处理重新分配给与所述第一处理装置不同的第二处理装置。

    • A searchable encryption resistant to frequency analysis. A conversion rule management device generates a conversion rule table associating a search keyword with a conversion keyword group. Based on the conversion rule table, a data registration device generates registration data associating encrypted data with an encrypted keyword, and registers the registration data in a server device. An information processing device obtains from the conversion rule table a conversion keyword group associated with a specified search keyword, generates an encrypted keyword group, and requests a data search by specifying the encrypted keyword group. Using as a search key an encrypted keyword included in the encrypted keyword group, the server device searches for encrypted data associated with the search key, and returns searched encrypted data. The information processing device decrypts the searched encrypted data, and outputs as a search result search data obtained by decryption.
    • 可搜索的加密功能可抵抗频率分析。 转换规则管理装置生成将搜索关键字与转换关键字组关联的转换规则表。 基于转换规则表,数据登记装置生成将加密数据与加密关键词相关联的登记数据,并将注册数据登记在服务器装置中。 信息处理装置从转换规则表获得与指定搜索关键字相关联的转换关键字组,生成加密关键字组,并通过指定加密的关键字组来请求数据搜索。 使用包括在加密关键字组中的加密关键字作为搜索关键字,服务器设备搜索与搜索关键字相关联的加密数据,并返回搜索到的加密数据。 信息处理装置对所搜索的加密数据进行解密,并输出作为通过解密得到的搜索结果的搜索结果。
