Data Encryption Standard (DES).
Public Key Cryptosystem

CONTENT


Data encryption refers to mathematical
calculations and algorithmic schemes that
transform plaintext into cyphertext, a form that
is non-readable to unauthorized parties. The
recipient of an encrypted message uses a key
which triggers the algorithm mechanism to
decrypt the data, transforming it to the original
plaintext version

Data encryption definition
Data encryption
*plaintext
*encryption algorithm
*public and private key
*cipher text
* decryption algorithm

A public key encryption
scheme has six ingredients


In symmetric
(Single key):
The encryption
and decryption keys
are the same.

Types of data encryption
.



Symmetric key
encryption is also
known as private
encryption, because it
uses the same key and
same cryptographic
algorithm to encrypt
and decrypt data.
A symmetric encryption scheme
has five ingredients


* Plaintext
* Encryption Algorithm
* Secret key
* Cipher Text
* Decription


In asymmetric
(two keys):
The encryption
and decryption
keys are
different.

.
.






The symmetric one key is used for symmetric
and a symmetric but in asymmetric different
keys are use for encryption and description.
In symmetric, sender and receiver must share
the algorithm and key but in a symmetric
sender and receiver must have one matched
pair of keys.
In symmetric key must be kept secret but in
asymmetric two keys must of kept secret.

Difference b/w Asymmetric &
Symmetric Encryption
