Executive Summary

Key agreement protocols are designed to provide two or more specified parties communicating over public channels with a common shared secret key, which may subsequently be used to exchange information among communicating parties. Therefore, building secure key agreement protocols over open networks is essential in information security. Error Correcting Codes (ECC) is one of many tools made available for achieving data transmission. Low Density Parity-Check codes (LDPC), a linear block code which has the advantage that they provide the performance at that close to the limited capacity for many different channels and linear time complex algorithms for decoding.
