has not been tampered with; that is, that the data received entirely corresponds
with the original version of the same data.
token A hardware or software device that is associated with a slot in a PKCS #11

trust Confident reliance on a person or other entity. In a public-key infrastructure
(PKI), trust refers to the relationship between the user of a certificate and the
certificate authority (CA) that issued the certificate. If you trust a CA, you can
generally trust valid certificates issued by that CA.

divisions of an enterprise. The VPN allows the divisions to communicate over an
encrypted channel, allowing authenticated, confidential transactions that would
