Abstract

In this paper, we propose an efficient usage of an available conventional encryption algorithm IDEA for encrypting plain text of fixed length into plaintext of same length usually called as Cipher by using a plain text of fixed length called Main key. IDEA algorithm which is a symmetric block cipher accepts 64 bit digital data as input and encrypts the same into a cipher of same 64 bit digital data. Aside from the basic characteristics of IDEA, i.e. the input of 64 bit digital data and 128 bit key, our proposed work accepts a plain text of 80 characters as input and encrypts the same into another text of 80 characters using 16 text characters as main key. Furthermore, we demonstrated the results of implementation of IDEA structure on to a Field Programmable Gated Array with various performance parameters.
