Decoding of (Interleaved) Generalized Goppa Codes
Hedongliang Liu, Sabine Pircher, Alexander Zeh +1
Generalized Goppa codes are defined by a code locator set of polynomials and a Goppa polynomial . When the degree of all code locator polynomials in $\mathcal{L…
Parity-Based Concurrent Error Detection Schemes for the ChaCha Stream Cipher
Viola Rieger, Alexander Zeh
We propose two parity-based concurrent error detection schemes for the Quarterround of the ChaCha stream cipher to protect from transient and permanent faults. They offer a trade-o…
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…
Decoding of Repeated-Root Cyclic Codes up to New Bounds on Their Minimum Distance
Alexander Zeh, Markus Ulmschneider
The well-known approach of Bose, Ray-Chaudhuri and Hocquenghem and its generalization by Hartmann and Tzeng are lower bounds on the minimum distance of simple-root cyclic codes. We…
