    • The present invention discloses methods for protecting data integrity of updatable data against unauthorized modification. A method for protecting data integrity of updatable data in a storage system, the method including the steps of: storing a data copy of the data in the storage system; upon storing the data copy, transforming the data copy into at least one transformed copy of the data; storing at least one transformed copy in the storage system; upon a request to read the data, reading the data copy and at least one transformed copy; transform-comparing the data copy and at least one transformed copy; and designating the data integrity of the data as verified contingent upon the data copy and at least one transformed copy being identical.
    • 本发明公开了用于保护可更新数据的数据完整性以防止未经授权的修改的方法。 一种用于保护存储系统中可更新数据的数据完整性的方法,所述方法包括以下步骤:将所述数据的数据副本存储在所述存储系统中; 在存储数据副本时,将数据拷贝变换成数据的至少一个经变换的副本; 将至少一个转换的副本存储在所述存储系统中; 在读取数据的请求时,读取数据副本和至少一个转换的副本; 转换 - 比较数据副本和至少一个转换的副本; 并且指定数据的数据完整性,这是根据数据拷贝验证的,并且至少一个转换的拷贝是相同的。

    • A signed multiplication method and a corresponding device for multiplying a first multiplicand with a second multiplicand. The device stores the first multiplicand in a first register as a first vector of at least one respective digit and storing the second multiplicand in a second register as a second vector of at least one respective digit, each digit having a pre-determined number of bits. The method further converts the digits of the first vector and the second vector to corresponding digits of one bit less each than the pre-determined number of bits. A processor effects signed multiplication of the multiplicands.
    • 一种有符号乘法方法和用于将第一被乘数与第二被乘数相乘的相应装置。 设备将第一被乘数存储在第一寄存器中作为至少一个相应数字的第一向量,并将第二被乘数存储在第二寄存器中作为至少一个相应数字的第二向量,每个数字具有预定数量的位 。 该方法还将第一向量和第二向量的数字转换成比预定位数少一位的相应位数。 处理器对被乘数进行带符号乘法。
