摘要

Method for performing a protocol of reconciliation of keys based on the sharing of signs and use the present invention describes a method capable of performing a protocol of reconciliation of keys based on sharing of signals, achieving high levels of safety and G Arantindo secrecy and to the inviolability of information.It is a technique that extracts an encryption key from a continuous information (for example, a signal with a noise component) common to the two parties to exchange information. To promote the proper reconciliation of the signs, the technology proposal uses encoding / decoding iteratively by means of codes low density lattice codes (LDLC).The proposed method provides a refined and efficient approach that uses both LDLC to treat data strongly correlated. It can be used in various electronic devices that share sensitive information, such as mobile phones, portable computers, telecommunication apparatus, not limiting.
