Application: Masked decomposition of polynomials for lattice-based cryptography (Patent ID: US20230396436A1)

The patent by NXP Semiconductors NV describes a data processing system that involves a cryptographic operation for lattice-based cryptography. The system includes instructions for a masked decomposition of a polynomial into high and low parts, utilizing arithmetic shares. The process involves performing a rounded Euclidian division, extracting Boolean shares, unmasking the high part, calculating arithmetic shares of the low part, and executing a cryptographic function using the derived parts.

The claims in the patent detail the specific steps involved in the cryptographic operation, such as the Euclidian division process, extraction of Boolean shares, unmasking of high part, calculation of arithmetic shares for the low part, and the subsequent cryptographic function execution. The system also includes variations in the calculations based on different parameters like base a, prime modulus q, and power of 2 ?. Overall, the patent outlines a methodical approach to secure cryptographic operations using polynomial decomposition and arithmetic shares for enhanced security in data processing systems.
