Abstract

Son reveladas técnicas en las que un parámetro usado para un paquete codificado es cambiado. Si el codificado inicial de un paquete provoca que se genere un "paquete asesino" (killer packet), el paquete es re-codificado usando un valor diferente para el parámetro, de manera que un "paquete asesino" es evitado. En una red que emplea comunicaciones de espectros ensanchados por salto de frecuencia, un identificador de canal puede ser empleado como una entrada al algoritmo de codificación. En esta implementación, un paquete de datos dado será transmitido en un canal con una primera secuencia de bits cuando éste es codificado, y en otro canal con una secuencia diferente de bits. Si el paquete codificado para uno de estos canales resulta en un "paquete asesino", es estadísticamente poco probable que éste será un "paquete asesino" cuando es retransmitido en el otro canal.
