Explore post-compromise security in self-encryption during this conference talk from the 2021 ITC Conference. Delve into the implications of state leakage in applications like cloud storage and 0-RTT session resumptions. Examine the relationship between post-compromise security and state size inflation, discovering why a super-linear state size is necessary for active ciphertexts. Learn about the application of these findings to cloud storage, session resumption, and secure messaging. Gain insights into constructing a secure scheme that matches the established bound on state size. Presented by Gwangbae Choi, F. Betül Durak, and Serge Vaudenay from the Paul G. Allen School, this 21-minute talk offers a deep dive into cutting-edge cryptographic research.
