<p>A method for allowing a first party and a second party to obtain shared secret information is provided. The method comprises the steps of: obtaining, by the first party, a sequence of values A=X+N A where X is a sequence of values and N A is a random sequence associated with the first party; obtaining, by the second party, a sequence of values B=X+N B where N B is a random sequence associated with the second party; performing, by the first and second parties, a data matching procedure to identify corresponding pairs of values, <u>a</u> <u> j </u>, <u>b</u> <u> j </u>, in respective sequences <u> A </u> and <u> B </u> that match, wherein sequences <u> A </u> and <u> B </u> are discrete-valued sequences equal to, derived from, or derived using, sequences A and B; wherein the shared secret information is equal to, or derived from, or derived using, the matching values in sequences A and B.</p> |
