Hello! could someone help me with this problem?
If you visit the website "www.uib.no", you will
observe that the connection is using the HTTPS protocol. This means
that UiB identifies itself using a digital signature which can be
verified using UiB’s public key; and the fact that what is shown as
UiB’s public key really is UiB’s public key is guaranteed by the
signature of a certification authority, whose public key is
guaranteed by an even higher level authority, etc. For this
problem, use the tools available in the browser to investigate
the chain of trust guaranteeing the security of the HTTPS
connection to UiB. More precisely, list all all entities involved
in the chain of trust (starting from UiB), and for each of them,
list:
• what digital signature algorithm was used to authenticate
them;
• what their public key is;
• what are the public parameters used in the algorithm (e.g. the
prime number p for RSA).
