Application of the societal risk assessment method

As the number of qubits in quantum computers increases, there is growing interest in the potential and the risks. This paper zooms in on the risks posed by quantum computers on public key infrastructures (PKI). The main objective of this study is to provide a preliminary overview of the main societal risks posed by quantum computing on PKI-based digital systems. More precisely, we look at the effects of a quantum computer's arrival before adequate measures are taken to migrate all cryptographic algorithms to a quantum-safe equivalent.
