If the University allows this, it suggests a hole in their data
security policies. Assuming they are up to scratch with their own
firewall, anti-virus, security updates, etc. they have no control over
such things on the private computers of their staff. It sounds like
what you actually need is, for example, a University laptop to access
your University email when away from your office.

Nobody *has to* sign *any* key unless they want to.

In the case of your University key, why does it need signatures from
anybody other than the University's own IT or security departments?
And does the University set an additional decryption key (so that
communications can be answered in the event of a staff member being
unexpectedly unavailable) and a designated revoker (for use as soon as
a staff member leaves)?
