Fuzzy Authentication using Rank Distance
Alessandro Neri, Joachim Rosenthal, Davide Schipani
Fuzzy authentication allows authentication based on the fuzzy matching of two objects, for example based on the similarity of two strings in the Hamming metric, or on the similiari…
An Application of Group Theory in Confidential Network Communications
Juan Antonio Lopez-Ramos, Joachim Rosenthal, Davide Schipani +1
A new proposal for group key exchange is introduced which proves to be both efficient and secure and compares favorably with state of the art protocols.
Involutions, Trace Maps, and Pseudorandom Numbers
Michele Elia, Davide Schipani
Interesting properties of the partitions of a finite field induced by the combination of involutions and trace maps are studied. The special features of involutions o…
An Active Attack on a Multiparty Key Exchange Protocol
Reto Schnyder, Juan Antonio Lopez-Ramos, Joachim Rosenthal +1
The multiparty key exchange introduced in Steiner et al.\@ and presented in more general form by the authors is known to be secure against passive attacks. In this paper, an active…
Group key management based on semigroup actions
Juan Antonio Lopez-Ramos, Joachim Rosenthal, Davide Schipani +1
In this work we provide a suite of protocols for group key management based on general semigroup actions. Construction of the key is made in a distributed and collaborative way. Ex…
Subspace Fuzzy Vault
Kyle Marshall, Davide Schipani, Anna-Lena Trautmann +1
Fuzzy vault is a scheme providing secure authentication based on fuzzy matching of sets. A major application is the use of biometric features for authentication, whereby unencrypte…
