This parameter isused to indicate the algorithm used for the security processing.
This parameter MUST be authenticiated when support is provided by the algorithm (AEAD algorithms) or construction (sign and mac).
This authentication can be done either by placing the header in the protected header bucket or by supplying it as part of the applications external data.
