Modern-day computer security relies heavily on cryp

tography as a means to protect the data

that we have become increasingly reliant on. The m

ain research in computer security domain

is how to enhance the speed of RSA algorithm. The c

omputing capability of Graphic Processing

Unit as a co-processor of the CPU can leverage ma

ssive-parallelism. This paper presents a

novel algorithm for calculating modulo value that

can process large power of numbers

which otherwise are not supported by built-in data

types. First the traditional algorithm is

studied. Secondly, the parallelized RSA algorithm i

s designed using CUDA framework. Thirdly,

the designed algorithm is realized for small prim

e numbers and large prime number . As a

result the main fundamental problem of RSA algorith

m such as speed and use of poor or

small prime numbers that has led to significant s

ecurity holes, despite the RSA algorithm's

mathematical

soundness can be alleviated by this algorithm
