Example : If Chrysler, Ford, and GM each choose their production levels so that no company can make more money by changing their choice, it’s a Nash Equilibrium Prisoner’s Dilemma : Two criminals are arrested and interrogated separately. Each has two ...

Role of Cryptography in Information Security |Cryptography Techniques

Topics Covered: Role of Cryptography in Information Security.

1.) What is Cryptanalysis?

Cryptanalysis is a technique decoding messages from a non-readable format back to a readable format.

2.) What is Plain text?

Plain text means Clear text/ Original Message. Plain Text can be understood by anybody knowing the language. For Example Communication Language used here: English and Message: Hello Everyone 

Plain Text = Clear Text [the message that can be understood by both sender and receiver and also by anyone else who gets access to that message].

3.) What is the Cipher Text?

Ciphertext means Codified Message / Encrypted Message / Unreadable Message. When Plain Text is Encrypted, the resulting message is Cipher Text.

4.) What is Encryption? 

The Process of Converting from Plain text to Cipher Text. Also known as Enciphering. 

5.) What is Decryption?

The Process of restoring the Plain text from Cipher Text. Also known as Deciphering. 

6.) Elements of a Cryptographic operation

7.) Substitution Techniques [caesar cipher]

In the substitution cipher technique, the character of plain text is replaced by other characters, symbols, or numbers.  An example of a Substitution Cipher is Caesar Cipher. 

Caesar Cipher Example:

Replace each letter of the alphabet with the letter standing three places down the alphabet.
