Error-tolerant secure key leasing for quantum decryption keys in public-key encryption
Duo Xu, Yuki Takeuchi
We propose the first error-tolerant secure key leasing (SKL) for public-key encryption. As with SKL in prior works, our protocol consists of a lessor and lessee. In the protocol, t…
Computational Certified Deletion Property of Magic Square Game and its Application to Classical Secure Key Leasing
Yuki Takeuchi, Duo Xu
We present the first construction of a computational Certified Deletion Property (CDP) achievable with classical communication, derived from the compilation of the non-local Magic…
A Simple Technique for the Converse of Finite Blocklength Multiple Access Channels
Duo Xu
A converse for the Discrete Memoryless Multiple Access Channel is given. The result in [13] is refined, and the third order term is obtained. Moreover, our proof is much simpler th…
The Redundancy of Slepian-Wolf Coding Revisited
Duo Xu
[Draft] In this paper, the redundancy of Slepian Wolf coding is revisited. Applying the random binning and converse technique in \cite{yang}, the same results in \cite{he} are obta…
