Abstract
Mechanisms are provided for performing ciphertext nullification operations. The mechanisms receive a ciphertext in nullification logic of a cryptographic circuit, where the cryptographic circuit comprises one or more cryptographic functions to be performed on the ciphertext. The mechanisms determine, by the nullification logic, whether the received ciphertext is to be nullified. In response to the determination indicating that the ciphertext is to be nullified, the mechanisms generate, by the nullification logic, a nullified ciphertext and output the nullified ciphertext. In response to the determination indicating that the ciphertext is not to be nullified, the nullification logic outputs the received ciphertext.
