Re: [sfc] Erik Kline's No Objection on draft-ietf-sfc-nsh-integrity-06: (with COMMENT)

[[e-mail]]

The timestamp is not an input for encrypting data. However, it is part of the data covered by integrity. This is shown, for example, in Figures 6 and 7 and the "Message Authentication Code" description. 

Cheers,
Med
