Apparatus method for establishing a Key sequence to ensure the communication through a Communication Channel between a First transceiver and a Second transceiver

摘要

The characteristics of a Communication Channel are used to establish Key sequences for use in Information comunicadaencriptada.In One embodiment, these characteristics are the impedances of the visual Channel untransceptor Hoisted from the other and vice versa.Keys can be set with equivalent calculation to a decoding procedure subject distanceAnd the key to establish a dorutilizado decodes p can be used to process the subsequent Data Transmission.It provides an alternative mechanism to establish and share Key sequences that depends on a process fu00edsicocomparado with Classical and Public Key cryptographic Systems,The cualcada Party need not generate a pseudo randomized quantity because the necessary randomness is provided by the properties of the Communication Channel in itself.Through the use of a Channel Decoder d e,The probability that two users establish the same SECRET KEY essustancialmente one and the probability that an eavesdropper set the same key is substantially Zero.Also, the amount declav is possible that is large enough to find the right through a search exhautiva is not feasible.
