Abstract

Método y sistema para la cogeneración asíncrona y no notificada de claves simétricas secretas criptográficas en ubicaciones espacialmente distantes a través de un sistema distribuido. El método comprende: a) requerir, por un primer usuario a un primer sistema cogenerador/gestor de claves, que inicie una comunicación con un segundo usuario; b) solicitar, dicho primer sistema cogenerador/gestor de claves a dicho primer usuario, un bloque de clave secreta identificado; c) entregar, dicho primer usuario a dicho primer sistema cogenerador/gestor de claves, dicho bloque de clave secreta identificado solicitado; d) establecer una comunicación entre dichos usuarios; e) entregar, dicho primer usuario a dicho segundo usuario, un bloque de cabecera que identifica dicho bloque de clave secreta identificado; f) enviar, dicho segundo usuario a un segundo sistema cogenerador/gestor de claves, dicho bloque de cabecera; y g) entregar, dicho segundo sistema cogenerador/gestor de claves a dicho segundo usuario, el resto del bloque de clave secreta identificado; el sistema está adaptado para implementar el método.Method and system for asynchronous and unreported cogeneration of cryptographic secret symmetric keys in spatially distant locations through a distributed system. The method comprises: a) requiring, for a first user, a first cogenerator / key manager system, to initiate a communication with a second user; b) request, said first cogenerator / key manager system from said first user, an identified secret key block; c) deliver, said first user to said first cogenerator / key manager system, said identified secret key block requested; d) establish communication between said users; e) deliver, said first user to said second user, a header block identifying said identified secret key block; f) sending said second user to a second cogenerator / key manager system, said header block; and g) delivering, said second cogenerator / key manager system to said second user, the rest of the secret key block identified; The system is adapted to implement the method.
