Abstract
Un método y sistema para procesamiento seguro de material de clave de autenticación en una red inalámbrica ad hoc permiten la distribución segura del material de clave de autenticación entre un autenticador de malla (110) y un distribuidor de clave de malla (115), el cual puede estar separado por múltiples enlaces inalámbricos; el método incluye derivar una clave transitoria en par para distribución de clave (PTK-KD) utilizando un elemento de información de seguridad de titular de clave de malla (MKHSIE); una clave maestra en par de autenticador de malla (PMK-MA) entonces es solicitada utilizando un primer elemento de información de clave codificada de malla (MEKIE) que incluye información de origen de datos; al utilizar la clave transitoria en par para la distribución de clave (PTK-KD), un segundo elemento de información de clave codificada de malla (MEKIE) entonces es decodificado para obtener la clave maestra en par de autenticador de malla (PMK-MA).
