Title	CYBER; Quantum-Safe Cryptography (QSC); Impact of Quantum Computing on Symmetric Cryptography Impact of Quantum Computing on Symmetric Cryptography
Scope and Field of Application	This work item will give an overview of the impact of quantum computing on symmetric algorithms such as block ciphers and hash functions. It will discuss the practicality of parallelising Grover’s algorithm, the effect of limiting quantum circuit depth, and the overhead from quantum error correction. It supplements ETSI GR QSC 006 (Limits to quantum computing applied to symmetric keys sizes) by summarising current quantum resource estimates for attacks against widely used symmetric algorithms with reasonable circuit depth assumptions. It will also provide guidance on the need to increase symmetric key lengths for a range of different use cases.
