Primitives for Quantum Enabled Security
Abstract
The aim of this project is to explore new cryptographic primitives based on quantum mechanics which can be used as the building blocks of future secure networks and secure computing systems. Quantum cryptography offers two advantages over approaches based entirely on conventional computing: quantum mechanics can enable some cryptographic primitives to be enabled with provable security which can only be realized using conventional approaches when assumptions are made about the adversary’s computing power, and quantum mechanics can also enable new primitives which are not possible in the classical world even when computational assumptions are made. We will explore both possibilities, particularly focusing on the types of primitives useful in a multi-user setting. To achieve this goal, we will pursue two parallel approaches. The first will be by working backwards from particular desired functionality, attempting to replace certain functionality found in public-key infrastructure and web of trust systems via interactive protocols rather than the digital sig-nature approach commonly used. The second approach will be by focusing on particular quantum techniques used in blind quantum computing protocols to extend their functionality in the direction of trapdoor functions, a common tool in many cryptographic applications. The project is expected to produce a number of new cryptographic primitives which will enable improved security and enhanced functionality in future quantum computer networks.
