In this talk I explain that digital signatures are the most important cryptographic primitive for current and future IT security solutions. I discuss the security status of the digital signature schemes that are presently used. I show that potential quantum computer attacks threaten these schemes. I present XMSS, a practical signature scheme with provably minimal security requirements.
