A system and method for an unconditionally secure protocol to create identic al pads or keys between two parties communicating over any network is provided. The protocol is composed of three parts, as follows, Firstly, the two parties generate an initial correlated string K A, K B of length N from a finite alphabet in a pre-arranged way from a commonly known probabilistic vector of real numbers. Secondly, the two parties engage in Information Consolidation and Reconciliation in order to reconcile differences. Finally, Privacy Amplification is used to cancel any information that an eavesdropper may have acquired and to produce the key or pad. This key agreement protocol creates unconditionally secure cryptography with a symmetric key cryptosystem. Alternatively, the symmetric keys can be used as a one-time pad with unconditional security.</S DOAB>
