Embodiments of the invention relate to a computer-implemented method for performing a digital signature according to a public key signature scheme. The method comprises a step of computing a presignature. The method comprises further steps of providing a master secret key pair, the master secret key pair comprising a first master secret key and a second master secret key, and providing a master public key pair, the master public key pair comprising a first master public key and a second master public key. The method comprises further steps of deriving a secret subkey from the master secret key pair and deriving a public subkey from the master public key pair. The method further comprises performing the digital signature by means of the secret subkey and the computed presignature.
