Application: Processing of cryptographic data (Patent ID: US20230412370A1)
The patent filed by Infineon Technologies AG pertains to cryptographic data processing using two masking schemes of a shared secret, with a transformation between the schemes achieved by enforcing a specific type of calculation. This method aims to enhance security by preventing side channel attacks that could reveal the shared secret through statistical analysis of different calculation types.
The claims outline the specific types of calculations involved, the characteristics of the masking schemes (Boolean and arithmetic), and the parameters used to define the shared secret. The transformation process is detailed, including the extension of parameters and the utilization of Goubin's "Algorithm 1." The patent covers methods for cryptographic data processing, devices implementing these methods (such as security devices), and computer-readable mediums containing the necessary software code for execution. Overall, the patent focuses on improving the security of cryptographic systems by introducing a novel approach to masking schemes and transformations between them.
