The present invention is a method for outputting larger bit size pseudo-random number z; that is cryptographically secure. Since larger bit size pseudo- random numbers are being outputted, larger bit size segments of messages may be encrypted resulting in a speedier encryption process than encryption processes of the prior art. In one embodiment, the present invention is a pseudo-random number generator defined by a modular exponential function xi = g xt-i mod p . The output of the pseudo-random number generator being a pseudo-random number zi comprising a j-1 bit size segment of xi. The value of j being less than or equal to m-2c (i.e., j~m-2c). In an embodiment of the present invention, the pseudo-random number zi includes the j least significant bits of xi excluding the least significant bit of xi.
