Cyclic Codes with Locality and Availability
Lukas Holzbaur, Ragnar Freij-Hollanti, Antonia Wachter-Zeh
In this work codes with availability are constructed based on the cyclic \emph{locally repairable code} (LRC) construction by Tamo et al. and their extension to -locality by…
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…
Coding over Sets for DNA Storage
Andreas Lenz, Paul H. Siegel, Antonia Wachter-Zeh +1
In this paper we study error-correcting codes for the storage of data in synthetic deoxyribonucleic acid (DNA). We investigate a storage model where a data set is represented by an…
Private Information Retrieval over Random Linear Networks
Razane Tajeddine, Antonia Wachter-Zeh, Camilla Hollanti
In this paper, the problem of providing privacy to users requesting data over a network from a distributed storage system (DSS) is considered. The DSS, which is considered as the m…
A Public-Key Cryptosystem from Interleaved Goppa Codes
Molka Elleuch, Antonia Wachter-Zeh, Alexander Zeh
In this paper, a code-based public-key cryptosystem based on interleaved Goppa codes is presented. The scheme is based on encrypting several ciphertexts with the same Goppa code an…
Bounds and Constructions for Multi-Symbol Duplication Error Correcting Codes
Andreas Lenz, Niklas Jünger, Antonia Wachter-Zeh
In this paper, we study codes correcting duplications of consecutive symbols. These errors are known as tandem duplication errors, where a sequence of symbols is repeate…
Twisted Gabidulin Codes in the GPT Cryptosystem
Sven Puchinger, Julian Renner, Antonia Wachter-Zeh
In this paper, we investigate twisted Gabidulin codes in the GPT code-based public-key cryptosystem. We show that Overbeck's attack is not feasible for a subfamily of twisted Gabid…
Locality in Crisscross Error Correction
Hedongliang Liu, Lukas Holzbaur, Antonia Wachter-Zeh
The cover metric is suitable for describing the resilience against correlated errors in arrays, in particular crisscross errors, which makes it interesting for applications such as…
Private Streaming with Convolutional Codes
Lukas Holzbaur, Ragnar Freij-Hollanti, Antonia Wachter-Zeh +1
Recently, information-theoretic private information retrieval (PIR) from coded storage systems has gained a lot of attention, and a general star product PIR scheme was proposed. In…
Coding over Sets for DNA Storage
Andreas Lenz, Paul H. Siegel, Antonia Wachter-Zeh +1
In this paper, we study error-correcting codes for the storage of data in synthetic deoxyribonucleic acid (DNA). We investigate a storage model where data is represented by an unor…
List Decoding of Locally Repairable Codes
Lukas Holzbaur, Antonia Wachter-Zeh
We show that locally repairable codes (LRCs) can be list decoded efficiently beyond the Johnson radius for a large range of parameters by utilizing the local error correction capab…
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…
