• All numbers are 32-bit (8 hex) unless otherwise stated.
• Key consists of two 32-bit numbers, J and K, totaling the size to 64-bits.
• The result of the algorithm is a 32-bit authenticator value, Z.

In the algorithm, there are many functions defined for different operations. But, here the algorithm is explained in very simple and easiest way. The data flow diagram helps to explain the algorithm graphically.
