Binary convolutional codes with optimal column distances
Zita Abreu, Julia Lieb, Joachim Rosenthal
There exists a large literature of construction of convolutional codes with maximal or near maximal free distance. Much less is known about constructions of convolutional codes hav…
Criteria for the construction of MDS convolutional codes with good column distances
Zita Abreu, Julia Lieb, Raquel Pinto +1
Maximum-distance separable (MDS) convolutional codes are characterized by the property that their free distance reaches the generalized Singleton bound. In this paper, new criteria…
Self-Dual Convolutional Codes
Sebastian Heri, Julia Lieb, Joachim Rosenthal
This paper investigates the concept of self-dual convolutional code. We derive the basic properties of this interesting class of codes and we show how some of the techniques to con…
Efficient Description of some Classes of Codes using Group Algebras
Henry Chimal-Dzul, Niklas Gassner, Joachim Rosenthal +1
Circulant matrices are an important tool widely used in coding theory and cryptography. A circulant matrix is a square matrix whose rows are the cyclic shifts of the first row. Suc…
Cryptanalysis of some Nonabelian Group-Based Key Exchange Protocols
Simran Tinani, Carlo Matteotti, Joachim Rosenthal
In the recently emerging field of nonabelian group-based cryptography, a prominently used one-way function is the Conjugacy Search Problem (CSP), and two important classes of platf…
A Survey on Code-Based Cryptography
Violetta Weger, Niklas Gassner, Joachim Rosenthal
The improvements on quantum technology are threatening our daily cybersecurity, as a capable quantum computer can break all currently employed asymmetric cryptosystems. In preparat…
