    • Provided is a method for performing a full-text-based logic operation using hash, the method including: (a) generating a hash data structure having a logic state that varies according to a type of a logic operator, so as to correspond to a first logic operator; (b) inserting hash nodes corresponding to first operand data into buckets that are sequentially allocated from the hash data structure; and (c) if a type of the current logic operator is AND, selecting buckets that coincide with hash nodes corresponding to second operand data among buckets inserted in (b) in the hash data structure or buckets selected as resultant values of the previous operation, as resultant values and if the type of the current logic operator is OR, inserting hash nodes among the hash nodes corresponding to the second operation data that are not retrieved from the hash data structure into the buckets that are sequentially allocated from the hash data structure and selecting all effective buckets within the hash data structure as resultant values.

    • A storage count verification system is provided in which a client can verify the number of identical data items stored by a server without the server being notified of the results. A storage count verification system verifies whether a user device and a server device have identical data where search data requested by a user device is used to search data to be searched on a server device. The server device generates a public parameter for searching the data to be searched and transmits the generated public parameter to the user device. The user device is provided with a user generation unit for generating, on the basis of the public parameter received from the server device, a secret parameter that is for the search data and corresponds to the public parameter and a user encryption unit for encrypting the search data on the basis of the generated secret parameter.
    • 提供了一种存储计数验证系统,其中客户端可以验证服务器存储的相同数据项的数量,而不会将服务器通知结果。 存储计数验证系统验证用户设备和服务器设备是否具有相同的数据,其中用户设备请求的搜索数据被用于搜索在服务器设备上搜索的数据。 服务器设备生成用于搜索要搜索的数据的公共参数,并将生成的公共参数发送给用户设备。 用户装置设置有用户生成单元,用于基于从服务器装置接收到的公共参数,生成用于搜索数据并对应于公共参数的秘密参数,以及用于加密搜索的用户加密单元 基于生成的秘密参数的数据。

    • String hashing using a random number generator is disclosed. A method of implementations includes dividing an input stream provided to a hashing module into a plurality of subsets of bits, wherein each subset comprises a same number of bits and wherein each of the subsets of bits comprises an overlapping subset, augmenting a subset of the subsets of bits with a constant, entangling, by a mixer of the hashing module, the subset by an output of a number generator, adding a result of the entangling to an accumulator of the hashing module, repeating the augmenting, the entangling, and the adding on at least a portion of a next sequential subset of the subset of bits, and when all of the subsets of bits have been processed, returning a value in the accumulator as a hash result value.
    • 公开了使用随机数发生器的字符串散列。 一种实现方法包括将提供给散列模块的输入流划分成多个比特子集,其中每个子集包括相同数量的比特,并且其中每个比特子集包括重叠子集,增加子集的子集 通过散列模块的混合器,通过数字发生器的输出将纠错的结果加到哈希模块的累加器中,重复增加,纠缠和加法 在比特的子集的下一个顺序子集的至少一部分上,并且当所有比特的子集已被处理时,将累加器中的值作为散列结果值返回。
