Techniques are provided for generation of an RSA modulus having a predetermined portion. The predetermined portion may be the leading digits of the modulus, or split between the leading and trailing digits of the modulus. The resulting RSA modulus has the same security level as conventional RSA moduli, but requires less storage space. Significant performance improvements may be obtained for encryption, decryption, digital signature generation and digital signature verification when using RSA moduli in a specifically chosen format, as the division portion of a modulo operation is accomplished using only multiplication operations, and without using division operations.
