Résumé

We examine networks that employ network coding, and are subject to Byzantine attacks. We consider systems where an appropriate network error correcting scheme is employed that is able to correct (up to a certain number of) Byzantine errors. Given this setup, we formulate the problem of locating these malicious nodes that insert errors. We utilize the subspace properties of (randomized) network coding to develop algorithms to locate the Byzantine attackers.

Error correction code

In computing, telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is that the sender encodes the message in a redundant way, most often by using an error correction code or error correcting code (ECC). The redundancy allows the receiver not only to detect errors that may occur anywhere in the message, but often to correct a limited number of errors.

Théorie des codes

En théorie de l'information, la théorie des codes traite des codes et de leurs propriétés et de leurs aptitudes à servir sur différents canaux de communication. On distingue deux modèles de communication : avec et sans bruit. Sans bruit, le codage de source suffit à la communication. Avec bruit, la communication est possible avec les codes correcteurs. En définissant l'information de façon mathématique, l'étape fondatrice de la théorie des codes a été franchie par Claude Shannon.

Linear network coding

In computer networking, linear network coding is a program in which intermediate nodes transmit data from source nodes to sink nodes by means of linear combinations. Linear network coding may be used to improve a network's throughput, efficiency, and scalability, as well as reducing attacks and eavesdropping. The nodes of a network take several packets and combine for transmission. This process may be used to attain the maximum possible information flow in a network.

Task-driven neural network models predict neural dynamics of proprioception: Neural network model weights

Axel Bisi, Alberto Silvio Chiappa, Alexander Mathis, Alessandro Marin Vargas

Proprioception tells the brain the state of the body based on distributed sensors in the body. However, the principles that govern proprioceptive processing from those distributed sensors are poorly understood. Here, we employ a task-driven neural network ...
