| Popis: | We propose a security model for evaluating the security of authenticated encryption schemes in the post-quantum setting. Our security model is based on a combination of the classical Bellare-Namprempre security model for authenticated encryption together with modifications from Boneh and Zhandry to handle message authentication against quantum adversaries. We give a generic construction based on the Bellare-Namprempre model for producing an authenticated encryption protocol from any quantum-resistant symmetric-key encryption scheme together with any authentication scheme digital signature scheme or MAC admitting a classical security reduction to a quantum-computationally hard problem. We give examples of suitable authentication schemes under the quantum random oracle model using the Boneh-Zhandry transformation. We also provide tables of communication overhead calculations and comparisons for various choices of component primitives in our construction. |
