4.5a Key Generation: A symmetric key K is generated and shared between communicating devices.

Encryption: Data D is encrypted using the key K:

$$\mathrm{C}={\mathrm{AES}}_{\mathrm{K}}\left(\mathrm{D}\right)$$

(15)

where C is the ciphertext.

b. Decryption: The cipher text C is decrypted using the same key K:
