Abstract
Web services are the main components for business communications these days. They provide communication between client and server through XML tags. The increasing number of vulnerabilities in XML tags demands much secured and efficient techniques. Security and efficiency of communication provided through XML tags are the primary concern of researchers. International Data Encryption Algorithm (IDEA) is considered as a secured algorithm, and it is used for encryption and decryption of XML text. The main concept behind the IDEA algorithm is to utilize three diverse mathematical operations: multiplication modulo, bitwise Exclusive OR, and addition modulo. Efficiency of the IDEA algorithm largely depends on these three operations. Aim of this research is to design a much efficient but secured encryption and decryption technique. We have modified the multiplication modulo operation and used it in IDEA algorithm to make it more efficient and used custom-level encryption and decryption methods to provide security. The modified algorithm is implemented and tested on the dynamic train seat allocation system developed using Web services. Our experimental result shows that the customized Idea algorithm encryption is 175.63% and decryption is 184.16% faster and secured than the IDEA algorithm.
