Abstract: Disclosed is a method for protecting message data. In the method, the message data is padded with padding bits generated based on a deterministic function performed on the message data. The padded message data is compressed to generate compressed data. A length of the compressed data is dependent on the padding bits. The compressed data is encrypted to generate encrypted message data.

Abstract: One feature pertains to an electronic device that includes a memory circuit and a processing circuit. The processing circuit computes a scalar multiplication output Z where Z=k·P by receiving an input multiplier k and a base P, and adds a modifier s to the input multiplier k to generate k′. The processing circuit also computes an intermediate scalar multiplication output Z′ where Z′=k′·P by using a digit expansion of k′ that includes a sequence of digits ki belonging to a digit set D. Additionally, the processing circuit subtracts s·P from Z′ to obtain the scalar multiplication output Z if k′ is odd or subtracts (s+1)·P from Z′ to obtain the scalar multiplication output Z if k′ is even. The scalar multiplier output Z may be used in a cryptographic security algorithm to secure data.
Abstract translation: 一个特征涉及包括存储器电路和处理电路的电子设备。 处理电路通过接收输入乘法器k和基数P来计算标量乘法输出Z，其中Z = k·P，并将修正符s加到输入乘法器k以产生k'。 处理电路还通过使用包括属于数字集D的数位ki的序列的k'的数字展开来计算Z'= k'·P的中间标量乘法输出Z'。另外，处理电路减去s· P从Z'获得标量乘法输出Z，如果k'为奇数，则从Z'中减去（s + 1）·P，以获得如果k'为偶数的标量乘法输出Z。 标量乘法器输出Z可用于加密安全算法中以保护数据。
