thefollowing services:
Messageintegrity—Ensures that messages have not been altered or destroyed in an unauthorized manner
andthat data sequences have not been altered to an extent greater than can occur non-maliciously.
• Message origin authentication—Ensures that the claimed identity of the user on whose behalf received

tounauthorized individuals,entities, or processes.
