A Novel Approach of Speedy-Highly Secured Data Transmission using Cascading of PDLZW and Arithmetic Coding with Cryptography

ABSTRACT
The spread of computing has led to an outburst in the volume of data in the communication world. The paper proposes the cascading of two algorithms: PDLZW and arithmetic coding with cryptography. With the hierarchical parallel dictionary set, the search time can be reduced significantly, and all these dictionaries are operated independently. While the results generated by arithmetic coding are close to the optimal value,. Since cascaded compression may achieve a higher compression ratio for the file but does not provide the required security aspects. Therefore, the advantage of cryptography has been taken by XORing the compressed data with the one-time
key, providing compression and security simultaneously. This paper proposes a new system JDCE, where compression is provided to the data twice before encrypting it to get it
ready for transmission.
