The key technical ingredient for our result is a protocol for classically-instructed parallel remote state preparation of BB84 states. This is a multi-round protocol between (classical) Alice and (quantum polynomial-time) Bob that allows Alice to certify that Bob must have prepared $n$ uniformly random BB84 states (up to a change of basis on his space). Furthermore, Alice knows which specific BB84 states Bob has prepared, while Bob himself does not. Hence, the situation at the end of this protocol is (almost) equivalent to one where Alice sent $n$ random BB84 states to Bob. This allows us to replace the step of preparing and sending BB84 states in existing protocols by our remote-state preparation protocol in a generic and modular way.

By contrast, only recently did the community discover that some of these distributed protocols can be made accountable by ensuring that correct processes irrevocably detect at least $t_0 + 1$ faulty processes responsible for any safety violation. This realization is particularly surprising (and positive) given that accountability is a powerful tool to mitigate safety violations in distributed protocols. Indeed, exposing crimes and introducing punishments naturally incentivize exemplarity.
In this paper, we propose a generic transformation of any distributed protocol that solves a decision task into its accountable version. To this end, we first demonstrate that accountability in non-synchronous distributed protocols implies the ability to detect commission faults. Specifically, we show that (1) detections not based on committed commission faults can be wrong (i.e., "false positives''), and (2) (luckily!) whenever safety is violated, "enough'' processes have committed commission faults.
Then, we illustrate why some of these faults, called equivocation faults, are easier to detect than some others, called evasion faults, thus concluding that equivocation faults are preferable causes of safety violations. Finally, we observe that the approach exploited by the well-studied simulation of crash failures on top of Byzantine ones can be slightly modified in order to ensure that the safety of a protocol could only be violated due to equivocation faults. Hence, we base the transformation on the aforementioned approach. Our transformation increases the communication and message complexities of the original distributed protocol by a quadratic multiplicative factor.

NTNU, Trondheim, Norway
The Department of Mathematical Sciences at NTNU is looking for a postdoc in public-key cryptography. The position is hosted by Jiaxin Pan. This position is funded by a project from the Research Council of Norway with focus on provable security. Potential topics are, but not limited to, digital signatures, zero-knowledge proofs, and post-quantum cryptography.
The candidate will work on theoretical aspects of public-key cryptography and is expected to publish at IACR conferences (such as Crypto, Eurocrypt, Asiacrypt, etc.) and renowned security conferences (such as IEEE S&P, ACM CCS, etc.). Thus, a track record of publications at these conferences is preferrable for the successful candidate.
Further details: The position holder will participate in many activities of the Cryptology Lab at NTNU which has 9 faculty members working on both applied and theoretical aspects of cryptology. The working place is in Trondheim, Norway. Trondheim is a modern European city with a rich cultural scene. It offers great opportunities for education (including international schools) and possibilities to enjoy nature, culture and family life and has low crime rates and clean air quality.
Application: More details are given here: https://www.jobbnorge.no/en/available-jobs/job/220131/postdoctoral-fellow-in-cryptography. We only accept applications from this jobbnorge.no page.
The deadline for application is the 31st of March, 2022.
