Sparsity and Privacy in Secret Sharing: A Fundamental Trade-Off
Rawad Bitar, Maximilian Egger, Antonia Wachter-Zeh +1
This work investigates the design of sparse secret sharing schemes that encode a sparse private matrix into sparse shares. This investigation is motivated by distributed computing,…
Generic Decoding of Restricted Errors
Marco Baldi, Sebastian Bitzer, Alessio Pavoni +3
Several recently proposed code-based cryptosystems base their security on a slightly generalized version of the classical (syndrome) decoding problem. Namely, in the so-called rest…
LIGA: A Cryptosystem Based on the Hardness of Rank-Metric List and Interleaved Decoding
Julian Renner, Sven Puchinger, Antonia Wachter-Zeh
We propose the new rank-metric code-based cryptosystem LIGA which is based on the hardness of list decoding and interleaved decoding of Gabidulin codes. LIGA is an improved variant…
Repairing the Faure-Loidreau Public-Key Cryptosystem
Antonia Wachter-Zeh, Sven Puchinger, Julian Renner
A repair of the Faure-Loidreau (FL) public-key code-based cryptosystem is proposed. The FL cryptosystem is based on the hardness of list decoding Gabidulin codes which are special…
