Title: Innovations and Contributions of Alexander Kesler
Introduction
Alexander Kesler is a notable inventor based in Newton, MA (US), recognized for his significant contributions to the field of cryptography. With a total of 5 patents to his name, he has developed innovative techniques that enhance the security and efficiency of cryptographic functions.
Latest Patents
One of his latest patents is titled "Redundancy AES masking basis for attack mitigation using lookup tables." This invention introduces techniques that replace many functions used in finite-field-based arithmetic with lookup tables (LUTs). By combining LUTs with redundancy-based protection, Kesler's method dramatically decreases the redundancy level, reduces power consumption, and increases the maximal frequency while maintaining the same protection level, latency, and performance. This improvement is applicable not only to AES but also to other algorithms based on finite field arithmetic, such as SM4, ARIA, and Camellia.
Another significant patent is "Carry-based differential power analysis and its application to testing for vulnerability of SHA-2 and HMAC-SHA-2 to side channel attack." This method tests the vulnerability of cryptographic functions to side-channel attacks by providing a plurality of input values and measuring side-channel leakage samples. The process involves iteratively splitting the samples into subsets, calculating respective values, and comparing them to discover bit values from their least significant bits to most significant bits.
