ok
but what the relation between encryption and Authentication key !!

[Sandeep Choudhary]

Hi,

Authentication and encryption are two intertwined technologies that help to insure that your data remains secure.

Authentication is the process of insuring that both ends of the connection: This applies not only to the entity trying to access a service (such as an end user) but to the entity providing the service, as well 

Encryption helps to insure that the information within a session is not compromised. This includes not only reading the information within a data stream, but altering it, as well.
