Abrégé
(EN)
In some aspects, an apparatus for encoding a stream of data for transmission to a receiver device comprises a memory device and a hardware processor. The memory device is a memory device configured to store at least one parameter associated with at least one cryptographic protocol, the at least one parameter identifying one or more cipher directives from a plurality of cipher directives including an exclusive-OR (XOR) function and a table lookup function. The hardware processor is configured to generate, for transmission to the receiver device, a frame comprising a first field identifying a custom or non-custom cryptographic scheme and a second field identifying a first cipher directive of the plurality of cipher directives.

Selon certains aspects, l'invention concerne un appareil pour coder un flux de données pour une transmission vers un dispositif récepteur comportant un dispositif de mémoire et un processeur matériel. Le dispositif de mémoire est un dispositif de mémoire configuré pour stocker au moins un paramètre associé à au moins un protocole cryptographique, ledit au moins un paramètre identifiant au moins une directive de chiffrement parmi une pluralité de directives de chiffrement comprenant une fonction OU exclusif (XOR) et une fonction de recherche. Le processeur matériel est configuré pour générer, en vue d'une transmission vers le dispositif récepteur, une trame comprenant un premier champ identifiant un schéma cryptographique personnalisé ou non personnalisé et un second champ identifiant une première directive de chiffrement parmi la pluralité de directives de chiffrement.
