Context- Alice and Bob are members of the same Kerberos realm. They are both currently logged in with active session keys from the Kerberos KDC (key distribution centre). As per the Kerberos standard, the KDC has created unique session keys for both Alice and Bob, and then discarded them once received by the respective users. Alice wants to access a resource owned by Bob and contacts the KDC to request the necessary material. Answer the following questions about this scenario:   Q- How can the KDC verify Alice’s identity after discarding her session key?

A considerable deal of attention is paid to the dissection of the Access Control list's constituent parts.

Cryptographic Data ObjectsB has just received the following message, which represents a cryptographic data object:{({(KPbB)KPrS mod KPbS}K1,{|(NB, NA, {{({K2}KPbB, NS)}(G1)KPrA mod NA}K1, {|{({G3}(KPbA)KPrS mod KPbS, G2)}K1|}KPrB)|}KPrA)}KBSThe following explains various terms in this object and some of the abbreviations used:• {M}K represents the encryption of some message/data M using the key K• {|M|}K represents the digital signing of some message/data M using the key K• NX represents a nonce (i.e. a fresh and possibly random number used once only) generatedby X• KpbX represents the public part of the key pair presumably owned by X• KprX represents the private part of the key pair presumably owned by X• KAB represents a symmetric key shared between A and B• K (or K1, K2, K3 etc.) represents some arbitrary key with no assumptions about its scope• M represents some alphanumeric/textual message with no assumptions• G1, G2, G3 etc. are prime numbersWhich of the following sets of keys,…

The WIMP layout is used in computer displays. Most WIMP implementations adhere to the Desktop metaphor, which links common actions to their physical counterparts. A file may be relocated by selecting it and dragging it to a new location, such as a folder or a filing cabinet. Provide two actions and their corresponding real-world instances.

Rutger University offers classes which visitors to the university can attend only if they are registered for the classes. Registration for the classes requires paying a nominal fee to the bursar, and you need account. The verification of visitors' registration is required in order for a visitor to attend a class, and this verification is done by a system administrator who is also required to log into the system. The verification is done through logging into the Rutgers registration system. If a visitor tries to log in to the system without being registered, an error message will be displayed by the system. Only a System Administrator will be able to create an account for a user of the system. The system administrator is also responsible for resetting login credentials (username and password) To get credit for the course, a participant must take a final exam which is set by a professor and uploaded to the system. The final exam when submitted by the student is reviewed by the professor…
