Abstract:
A white-box system and method for producing a digital signature of a message m, including: a white-box implementation of a symmetric cipher configured to produce a deterministic nonce value by encrypting the message m using a secret key; and a digital signature algorithm configured to produce a digital signature of the message m based upon the deterministic nonce, the message m, and a secret signing key.
