A certificate contains an identity, a public key, and signatures attesting that the public key belongs to the identity. Other fields that may be present include the organization (for example, university, company, or government) to which that identity belongs and perhaps suborganizations (college, department, program, branch, office). What security purpose do these other fields serve, if any?
Explain your answer.

Sometimes
these
other
fields
are
the
keys
to
establishing
trust.
For
instance,
my
use
case
may
cause
me
to
trust
anyone
with
a
valid
US
government
email
address,
and
having
that
email
address
be
part
of
a
certificate
may
be
sufficient
proof
as
long
as
I
trust
the
certificate
authority
that
issued
the
certificate
to
have
validated
that
information.

Showthat the following proposed protocol for a timestamp-ordered concurrency control is not recoverable.
Store with each data item the maximum timestamp of any (not necessarily committed) transaction that has read that item and the maximum timestamp of any (not necessarily committed) transaction that has written that item. When a transaction makes a request to read (write) a data item, if the timestamp of the requesting transaction is smaller than the write (read) timestamp in the item, restart the transaction; otherwise, grant the request.
