Abstract :
This paper proposes a method to prevent
parameter tampering on web services. Time based hash
encryption is able to give unpredictable output which
changes periodically ac-cording to input. The proposed
method uses different parts of function output as
authenti-cation key and parameter order. The
presented method has several characteristics. Each
encryption and decryption needs to be able to generate
the same VST. Vst used must have a periodic record so
that it is pos-sible to get Vs (t-1).Each used Vst works
without trouble on both time variants (tests 1-3) and
invariant (tests 3-5). From the Decrypt column, we can
see that, as a side effect, each pass parameter is
decrypted and cut off. To evaluate proposed work, we
make software to encrypt and decrypt a request. We
limit the test to having no delay.
Keywords :
Securing Client, Server Connections, Tampering, Encryption.
