METHOD FOR THE SECURE APPLICATION OF A CRYPTOGRAPHIC ALGORITHM OF THE RSA TYPE AND CORRESPONDING COMPONENT

摘要

The process involves finding the value of a public exponent among a set of probable predetermined values, if the value is not known a priori. Counter measure operations are implemented using the determined exponent value. Error attacks and hidden channels, particularly of differential and single power analyses type, likely to increase while implementing a private operation of cryptographic algorithm, are avoided. - Independent claims are also included for the following: - (1) an electronic component - (2) a chip card with an electronic component.
