Abstract: An efficient hashing technique uses w + w/2 operations to hash a string "w" words long rather than the w operations of the prior art. This efficiency is achieved by squaring the sum of the key and the string to be hashed rather than forming a product of the key and the string to be hashed.

Abstract: An efficient hashing technique uses (see above formula) operations to hash a string "w" words long rather than the w2 operations of the prior art. This efficiency is achieved by squaring the sum of the key and the string to be hashed rather than forming a product of the key and the string to be hashed. h(m)=((m + a)2 mod p)mod z,

Abstract: The present invention solves the aforementioned inefficiencies by providing an encryption or cipher method that uses the same pseudorandom function twice rather than different pseudorandom functions. Additionally, the present invention uses hashing functions that are highly efficient. The hashing functions of the present invention are square hashing functions that square a sum of a key and a data string rather than using a multiplication. As a result the hashing operation only requires operations rather than the w2 operations required by the inefficient hashing functions used in the prior art.. Additionally, the present invention replaces the exclusive ORed operations of the prior art with modular "n" summing operations.
