Summary:Various embodiments relate to a method for producing a digital signature using a white-box implementation of a cryptographic digital signature function, including: receiving a input message; hashing the input message; generating a nonce based upon the input message and the white-box implementation of the cryptographic digital signature function; and computing a digital signature of the input using the nonce.
