Consider a scenario with two security levels, Alice and Bob. Bob is Alice's boss. Bob must be able to read Alice's documents but not write anything to her documents.
I am using encryption keys to encrypt all of Alice's data, and then giving Bob the private key/ However I have realised this will not stop him editing it, just giving him the public key would allow him to edit it but not see it.
Basically how would Bob be able to see and not edit Alice's files?
homeworktag here, for good reason.
