Abstract
Disclosed are systems and techniques for enhanced protection of cryptographic key generation in cryptographic applications. In particular, described is a method and a system that performs the method of obtaining input numbers associated with a cryptographic application, generating masking matrix based on at least one random value, obtaining masked numbers using a matrix product of the MM and the input numbers, determining a greatest common divisor (GCD) of the masked numbers, identifying a GCD of the input numbers, and using the identified GCD to generate a cryptographic key.
