Abstract
Web applications have become part of daily life. They help us to aid the system with cross-platform functionality regardless of the location. Due to public environment and involvement of internet it has become vulnerable for several security threats. At this point, hackers attack may break down the security and leak the information. In web application data is recognized as an important corporate asset that needs to be safeguarded from unwanted internal or external threats. Data encryption not only provides data protection on sensitive data but also raise computation and memory overhead on web application during large data processing. Web Application always demands low processing overhead to keep computation as fast as possible. In the proposed hybrid model the AES algorithm is replaced by Blowfish security algorithm, which is faster than AES and ECC algorithm is replaced by RSA algorithm. ECC algorithm can provide the same level of security afforded by RSA with a large modulus and corresponding large key. To verify the originality of data MD5 algorithm is implemented and to authenticate the client modified Kerberos protocol is applied.
