I struggle with the terminology.  The way I (mis?)use the term
authentication, it can mean both:

Logging In: IKE, Kerberos, SIP digest...  I guess this is "session
authentication"

Per-packet trust mechanism: SHA1, MMH...  I guess this is "packet
authentication"

different chunks of security technology?
