Conventional Encryption Techniques

                         Conventional Encryption Techniques

• The secret key is also input to the encryption algorithm. 


• The key is a value independent of the plaintext. The feature of symmetric encryption is what makes it feasible for widespread use. 


• The fact that the algorithm need not be kept secret means that manufactures can and have developed low-cost chip implementations of data encryption algorithm. 


• With end-to-end encryption, the encryption process is carried out at the two end systems. 


• The source host or terminal encrypts the data. 


• Link encryption obscures header details but overall traffic volumes in networks and at end-points are still visible.


•  A term refers to the means of delivering a key to two parties that wish to exchange data, without allowing others to see the key is Key distribution.
