1. AN EFFICIENT OPERATOR BASED UNICODE CRYPTOGRAPHY ALGORITHM FOR TEXT, AUDIO AND VIDEO FILES

2. CRYPTOGRAPHY  In modern times, science of using mathematics to encrypt and decrypt data  Examples: ATM Cards, Computer passwords, E-Commerce

3. CONDITIONS TO BE SATISFIED  Authentication: verifying the identity of user  Privacy: only the intended user reads the message  Integrity: the exact original message received by user  Non-repudiation: proving that the sender really sent the message

4. CRYPTOGRAPHIC TECHNIQUES

5. OPERATORS IN ENCODING  Every plain text can be converted into numeric value irrespective of its magnitude. Value 1 Value 2 Value X* Plain Text Cipher Text Encoding

6. WHY UNICODE ?  Common standard-65536 characters available  100,000 code positions allocated to characters  Many code points not yet assigned  Many code points are permanent non characters  Hence Unicode mapping (UTF 16) is chosen

7. DESIGN USING UNICODE Plain Text Unicode Cipher Text Operator F(x)

8. KEY BINDING METHODS  Numeric key is binded  Entire Text Binding: - Each character key added - Inefficient method , hence avoided  Feed Back Based Security: - First character key added - Loop continued till end of the word or input - Current Char Key depends Previous Char input -No repetition

9.  Criteria for secret key: - Must be numeric value - Unique value range from 0 to 65536  Serial Digit Secret Key: - Depending on the operator , key is added to block - Key range is larger  String Structure Key Bind: -Series of characters instead of numbers -Key can have Unicode equivalent values

10. CONCLUSION  Thus Unicode character set provides better encoding algorithm  Hence it increases complexity of cipher text & provides better security for all file types
