The post-quantum Double Ratchet scenario
Generic Double-Authentication Preventing Signatures and a Post-Quantum Instantiation
... The theorem above is proven in Appendix E.2. 5 Conclusion In this work, we close two important gaps in the literature on DAPS. First, we present a generic DAPS construction, which, in contrast to [DRS18b], does not come ...
