摘要： The present invention relates to a method for performing an iterative calculation of exponentiation of a large datum, the method being implemented in an electronic device (DV1) and comprising calculations of squaring and multiplying large variables performed in parallel, by squaring (SB1) and multiplication (SM1) blocks, the method comprising steps of: while a temporary storage buffer memory is not full of unused squares, triggering a calculation by the squaring block for a bit of the exponent, when the squaring block is inactive, storing each square provided by the squaring block in the buffer memory, if the bit of the corresponding exponent is on 1, and while the buffer memory contains an unused square, triggering a calculation by the multiplication block concerning the unused square, when the multiplication block is inactive.
摘要翻译：本发明涉及一种用于执行大数据的取幂的迭代计算的方法，该方法在电子设备（DV1）中实现，并且包括通过平方（SB1）和乘法来并行执行的大变量的平方和相乘的计算（SM1）块，所述方法包括以下步骤：当临时存储缓冲存储器未填满未使用的正方形时，当平方块不活动时，触发平方块对于指数位的平方块的计算，存储由缓冲存储器中的平方块，如果相应指数的位为1，并且当缓冲存储器包含未使用的平方时，则当乘法块不活动时，触发相关块关于未使用的平方的计算。

摘要： A search system has a management device that stores compound data and a searcher device. The management device defines a similarity between query sequence data q representing a substructure or property of a substance that is input as a search condition at the searcher device and sequence data pi (i=1, 2, . . . , m) for substances stored in the database by means of a score T that takes a non-negative value when a Tversky index Si is greater than or equal to a threshold value θn/θd (where θn and θd are natural numbers that satisfy θn≦θd), calculates an encrypted value of the score T while the query sequence q is maintained in an encrypted state, and returns the encrypted value to the searcher device to thereby disclose information regarding whether or not similar compounds are present in the database while in a confidential state.
