Abstract:
Nowadays, online processing is increasing day
by day and security plays important role in online processing ,
especially in the area of government processes. There are
several security algorithms already presented. Among these
algorithms, digital signature is widely used in authentication
process and identification of owner. This system proposed an
approach for secured online vehicle annual licensing process
using digital signature for authentication and blowfish
symmetric algorithm for data encryption. Digital Signature is
used to assign the documents in order to safe communication
and verifying the right owner and real documents and
certificates. In the process of annual licensing processes,
documents need to send over the communication channel. There
may be unauthorized access of the documents and modification
of the documents while sending over the communication
channel. In order to avoid above problems, documents are
assigned using digital signature and Blowfish symmetric
algorithm is used to encrypt the signed documents. Blowfish is
simple encryption algorithm and key can be any length up to
448 bits. It is suitable for applications where the keys does not
change often, like a communication link or an automatic
document encryptor. It is significantly faster than most
encryption algorithms when implemented on 32-bit
microprocessors with large data caches.
