here both Alice and Bob share the same key
- How encryption takes place
- -Alice encrypts the plain text with the key and send the cipher text to the Bob
- -Alice sends the key to the Bob
- How decryprtion takes place
- -Bob receives the key from the Alice
- -Bob decrypts the cipher text with the help of the key send by the Alice
A Symmetric key
Here any body can encrypt the data because Public key know to everybody
Only the intented reciepient can decrypt the message
- How encryption takes place
- -As the public key known to every body any body can encrypt it
- -So the Alice encrypts the plain text by using the public key and send it to the Bob
- How decryption takes place
- -here Private key is only known to the intended reciepient
- -so by using his private key he can decrypt the message
