Project Implemented in the course of MSc in Applied Computer Science (Informatics)
Duration Project Details
01/09/2012 to
31/03/2013
Project :
Poly Alphabetic Approach for Data Encryption
Software/Programming Language Details :
MATLAB software version 11, MATLAB as programming language
Technical Details:
 Implementation of new Hybrid Encryption Technique which uses symmetric encryption
algorithm PASE, asymmetric encryption algorithm RSA.
 Implementation of Poly alphabetic Symmetric Encryption PASE.
 Implementation of Asymmetric Encryption Algorithm RSA for secret key handling.
 Implementation of Secure Hash Algorithm SHA256 for authentication.
 Implementation as Text Encryption and Image Encryption Technique.
Functional Details / Features:
 The proposed Encryption procedure has advantages of both symmetric and asymmetric
encryption techniques.
 The key management for the sharing of the secret key between the two parties is also
efficiently handled by this Encryption Procedure.
 This new encryption technique provides security to both the data and the secret key which
results in confidentiality and authentication.
