Abstract:When powerful quantum computers are built, they will break most of the public key cryptography schemes due to Shor’s quantum algorithm. Therefore, public key cryptography algorithm schemes that is secure against classical and quantum computers are needed. In this thesis, we study Picnic algorithm, a post-quantum digital signature scheme. Picnic digital signature algorithm has the security of symmetric-key primitives that is considered to be secure against quantum attacks. In Picnic algorithm, zero knowledge proof systems and circuits to compute their protocol are used.
