Q1. Alice and Bob are using RSA public key cryptography to send and receive information. Alice is using the following key pair (Private key: 7 and Public key: 5) whereas Bob’s key pair is (Private key: 11 and Public key: 7). Find the ciphertext (C) for the following messages (3 marks).

i) Message (M) = 9. Alice is sending a secret message to BoB.

ii) Message (M) = 6. Bob is sending Alice his signature.

Q2. Consider the network of a university. The network includes a number of servers which store important and sensitive data (such as user IDs, passwords, and student’s academic records), a wired network which is partially connected to the Internet, and a wireless extension which facilitates data access to students/staff on campus with portable devices. To protect user’s accounts, password files in the servers should be encrypted. To ensure efficiency of the authentication procedures, RC4 has been used as for password encryption. Explain why RC4 was selected in this application rather than RSA or LFSR based ciphers (3 marks).

Q3. In 2014, a security bug in the OpenSSL cryptography library was disclosed which could be exploited to compromise the secret keys used to identify the service providers and to encrypt the traffic. What is the name of the bug? Identify the security flaw exploited by the bug. What need to be done to keep your computer safe from this bug (2 marks)?

Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int last_access_timestamp; int reference_count; } Each process in the system has a page table that is simply an array of PTEs. Each process also has a pool of frames that is allocated. The frame pool for a process is represented as an array of integers, where each Integer represents the frame number of a frame that is free and is available for use by the process. Note that in order to get the frame number in the pool, you first need to access the integer in the array. This lab project aims to exercise the various policies for page replacement. In particular, we study the following three page-replacement policies: First-In-First-Out (FIFO) Least-Recently-Used (LRU) Least-Frequently-Used (LFU) In order to implement the above policies, we need to develop corresponding functions that process page accesses for a process. That is, for each process, given its page table, a logical page number being referenced and the free frame pool of the process, the functions should determine the memory frame number for the logical page. Also, the functions should modify the page table and the free frame pool appropriately. The details of the functions with respect to the different policies are described below. You need to develop code for these functions that implement the specifications. Place the code in a file called virtual.c. You should include the oslabs.h file.

(10 marks) c) Write your opinion on what you think would happen to its ratios if the company initiated cost-cutting measures that allowed it to hold lower levels of inventory and substantially decreased the cost of goods sold. No calculations are necessary. Think about which ratios would be affected by changes in these two accounts. (10 marks)
