Describe symmetric encryption. What is the weakness of this type of encryption?
What will be an ideal response?
Each of the aforementioned encryption and decryption methods requires the same algorithm and key-a secret key-to be used to both encipher and decipher the message. This is known as private key encryption, or symmetric encryption. Symmetric encryption is efficient and easy to process, as long as both the sender and the receiver possess the encryption key. Of course, if either copy of the key becomes compromised, an intermediary can decrypt and read the messages. One challenge in symmetric key encryption is getting a copy of the key to the receiver, a process that must be conducted out-of- band (that is, through a channel or band different from the one carrying the ciphertext) to avoid interception.
