Abstract

The embodiment of the invention provides a chip and a batch modular operation method for the chip. The chip is used for carrying out privacy calculation and comprises a bus interface, an input control module, an output control module and at least two operation cores; the bus interface is used for receiving n input data from a host side; the input control module is used for distributing n parts of input data to n operation cores for parallel modular operation based on a multi-core scheduling algorithm; the operation cores are used for performing modular operation on received input data based on a preset Montgomery modular multiplication algorithm, each operation core comprises an independent modular residue calculation unit or a plurality of operation cores share one modular residue calculation unit, and the modular residue calculation unit is used for performing modular residue calculation on a cyclic calculation result in the Montgomery modular multiplication algorithm so as to obtain a modular operation result; and the output control module is used for controlling n modular operation results calculated by the n operation cores to be sequentially output to a host side through the bus interface. According to the embodiment of the invention, the privacy calculation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a chip and a batch modular operation method for the chip. Background technique [0002] In privacy calculations based on cryptographic protocols, basic operations such as modular exponentiation and modular multiplication of large integers are usually required. In a large number of privacy calculations, the calculation process is based on ciphertext (to protect user privacy). The addition and multiplication operations in plaintext correspond to semi-homomorphic and homomorphic operations in ciphertext. These operations are usually used to a large number of modular exponentiation or modular multiplication operations. [0003] In order to improve the efficiency of privacy calculations, the Montgomery algorithm can be used to accelerate these basic operations such as modular exponentiation and modular multiplication. However, when the amount of computing data is large, even if th...
