A well-known university is considering investing in an online
system that would allow students to share their degree transcript
with future employers. The system will publish encrypted details of
each student’s transcript to a webpage unique to that student. The
student will be given a public key by the University that will
unencrypt their transcript when a user navigates to the webpage
(they can share the key with employers), while the University will
retain the private key in case the transcript needs updating in the
future (for example if the student studies a further degree).
Explain how, as well as ensuring the transcript data is protected
from casual browsing, the University could make use of public /
private key pairs to enable the ownership and validity of the
transcript data to be proved by the end user. Please draw a diagram
of the data exchange to illustrate.
