Abstract
In one embodiment, cryptographic transformation of a message is performed by first performing a table initiation phase to populate a data structure. Then, a first random number multiplied by a public key is added to each value in the data structure, in modulo of a second random number multiplied by the public key. Then an exponentiation phase is performed, wherein each modular multiplication and square operation in the exponentiation phase is performed in modulo of the second random number multiplied by the public key, producing a result. Then the result of the exponentiation phase is reduced in modulo of the public key. The introduction of the random numbers aids in the prevention of potential security breaches from the deduction of operands in the table initiation phase by malicious individuals.
