Problem faced by today's communicators is not only security but also the speed of communication and size of content. In the present paper, a scheme has been proposed which uses the concept of compression and data encryption. In first phase the focus has been made on data compression and cryptography. In the next phase the authors have emphasized on compression cryptosystem. Finally, proposed technique has been discussed which used the concept of data compression and encryption. In this first data is compressed to reduce the size of the data and increase the data transfer rate. Thereafter compress data is encrypted to provide security. Hence the proposed technique is effective that can reduce data size, increase data transfer rate and provide the security during communication.
