The many applications of model checking are well shown by the study of security protocols.
How does the Two-Phase Locking (2PL) protocol work, and what are its limitations in a highly concurrent environment?
Public Key Authority is one such instance. The Public Key Authority must prepare a request for B's public key before delivering a message to A (E(PRauth[PUB || Request || Time 1]). It is debated if the letter A should be used to decipher the message.
Computer Science Need a detailed answer with a proper diagram Your task is to read up on the Kerberos protocol, Summarise it in a single diagram (you can reuse an existing diagram with reference) and determine whether or not it has forward secrecy. Write a short paragraph justifying exactly how it has forward secrecy (if it does), or how it does NOT have forward secrecy if it does not. If the latter is true, then modify the design of Kerberos to add forward secrecy to it.
Here's how to secure your bike: Only things with a higher number may be locked again after being unlocked. Locks may be unlocked at any moment. All the locks are X-locks. Demonstrate how serializability is not ensured by the protocol.
Exercise 2 ( In module 4 we discussed many examples of security protocols using formal notation. For instance, we studied how a dual-factor authentication works when a password generator is used: S → U : N U → P : N, PIN P → U : {N,PIN}K U → S: {N,PIN}K Can you modify the set of rules outlined above to describe the protocol of dual-factor authentication when a mobile device is involved? To receive full credit, please submit 1. a high-level overview of how the protocol would work (e.g. the mobile phone might provide a PIN to the user as opposed to just "clicking" on a button directly on the phone) 2. the description of the protocol using the formal notation
With persistent communication, a receiver generally has its own local buffer where messages can be stored when the receiver is not executing. To create such a buffer, we may need to specify its size. Give an argument why this is preferable, as well as one against specification of the size.

Your company is building a computer network, and you are asked to write an algorithm for achieving distributed mutual exclusion. Which scheme will you use? Explain your choice.
- Consider another carelessly written Web application, which uses a servlet that checks if there was an active session, but does not check if the user is authorized to access that page, instead depending on the fact that a link to the page is shown only to authorized users. What is the risk with this scheme? (There was a real instance where applicants to a college admissions site could, after logging into the Web site, exploit this loophole and view information they were not authorized to see; the unauthorized access was however detected, and those who accessed the information were punished by being denied admission.)
2. Recall the concept of Physically Unclonable Functions, which are an importantcomponent of hardware based security. Here is a simple scenario and simple protocol usingPUFs for authenticating a tag. In the protocol below, the Reader stores ALL possiblecombinations of Challenge-Response pairs for every tag it needs to authenticate. Duringauthentication, the Reader broadcasts the ID of the tag, and a greeting (Gn ). Every tag maysee this message, but only the one with the right ID will process the message. The right tagwith the ID in the message will then feed the greeting to its PUF and compute the responseSn. The response is then sent to the Reader. This should be clear from the Figure below. Forthe next round of authenticating the same Tag, the process repeats with a new Greeting(G n+1 ). Since the Reader has the responses, authentication is straightforward. Recall thatChallenges and Responses are typically 128 or 256 bit strings for RFIDs.From the protocol, and class, it should be…
