ENHANCED AES FOR TEXT ENCRYPTION USING TIMESTAMP (2D)

Abstract

The project aims at strengthening the AES algorithm further, by using another dimension for enhancing
the encryption technique. A generation of time stamp is introduced for every transaction, which shall work as an
additional level of security. Since the exact time stamp will only be known to the user, the encryption becomes safer.
The introduction of the time stamp also makes the algorithm asymmetric in nature, a definite up from the symmetric
nature. Further- more, an additional, selective key method is introduced, in which, the user is asked to select any
three alpha-numeric values of his choice, which shall never be used in the key generation. If any such value is
generated in the key, the key shall be further modified to suit the user’s preference. If an intruder, tries to break the
encryption and uses the aforementioned values in the key, an intrusion detection system will be activated, and the
owner will be notified. And to neglect the chances of relative key attack, only the 128 bit AES is being used, which
will further strengthen the system.
