Scope
The present document gives an overview of the current understanding and best practice in academia and industry about quantum-safe cryptography (QSC). It focuses on identifying and assessing cryptographic primitives that have been proposed for efficient key establishment and authentication applications@ and which may be suitable for standardization by ETSI and subsequent use by industry to develop quantum-safe solutions for real-world applications. QSC is a rapidly growing area of research. There are already academic conference series such as PQC and workshops have been established by ETSI/IQC [i.1] and NIST. The European Commission has recently granted funding to two QSC projects under the Horizon 2020 framework: SAFEcrypto [i.2] and PQCrypto [i.3] and [i.4]. The present document draws on all these research efforts. The present document will cover three main areas. Clauses 4 and 5 discuss the types of primitives being considered and describe an assessment framework; clauses 6 to 10 discuss some representative cryptographic primitives; and clause 11 gives a preliminary discussion of key sizes
