Abstract: 
One major goal of classical cryptography is to certify the origin of a message: a digital signature authenticates an electronic document and ensures that it has not been tampered with. The security of all such public key digital signature schemes depends on the inability of a forger to solve certain difficult mathematical problems.
However, with a quantum computer some of these issues become tractable. In this talk I will present a quantum digital signature scheme whose security is based on fundamental principles of quantum physics and I will highlight the differences between a classical and a quantum digital signature algorithm.
