Claim 24:
25. The system of claim 23 wherein the five different passes comprise:
a first pass comprising a first message, wherein the first message is communicated from the first computer system to the second computer system, and wherein the first computer system is configured to generate the first message using a permutation operation based on the first parameter and a modular arithmetic operation based on the second parameter;
a second pass comprising a second message, wherein the second message is communicated from the second computer system to the first computer system, and wherein the second computer system is configured to generate the second message using a permutation operation based on the third parameter and a modular arithmetic operation based on the fourth parameter;
a third pass comprising a third message, wherein the third message is communicated from the first computer system to the second computer system, and wherein the first computer system is configured to generate the third message using a permutation operation based on the first parameter and a modular arithmetic operation based on a sixth parameter, wherein the sixth parameter is not shared with the second computer system in unobscured form;
a fourth pass comprising a fourth message, wherein the fourth message is communicated from the second computer system to the first computer system, and wherein the second computer system is configured to generate the fourth message using a permutation operation based on the fifth parameter and a modular arithmetic operation based on the third parameter; and
a fifth pass comprising a fifth message, wherein the fifth message is communicated from the first computer system to the second computer system, and wherein the first computer system is configured to generate the fifth message using a permutation operation based on a seventh parameter and a modular arithmetic operation based on the first parameter, wherein the seventh parameter is not shared with the second computer system in unobscured form.
