APCYP TOPIC 5 EXAM REVIEW QUESTIONS AND ANSWERS, VERIFIED/ Explain Message Digest or Hash - 1. Message digest, hash, or CHECKSUM is a fixed-length of sequence of digits uniquely representing a message 2. used to verify the integrity of the message against unauthorized or unintentional modifications 3. any changes to the original message will result in a different message digest 4. MS algorithms are open and available in the public domain Name the 3 Desirable Properties of a Hash/MD Func...

What 5 services does network security provide? - Answer Message Confidentiality Message Integrity Message Authentication Messsage Nonrepudiation Entity Authentication How can you provide message confidentiality? - Answer Use encryption. How do you provide message integrity? - Answer Encryption doesn't help here. Hash the document (message) to get the fingerprint (message digest) and keep the digest secret! What are the 3 criteria for a hash function? - Answer One way-ness ...

CSD201 Exam Questions and Answers Consider the following function void funt(int n) {ifn > 0) {S(" " +n % 5); fun(n); } } What will happen if the statement fun(33); is run? A. The run-time stack overflows, halting the program B. The results are nondeterministic C. The operating system detects the infinite recursion because ofthe "repeated state" D. The program keeps running until you press Ctrl-C - Correct Answer️️ -a (ảnh) Given the division hash function h(x) = x%M, w...

Hash mechanism that is used for data integrity assurance. Based on a one-way mathematical function: functions that are relatively easy to compute, but significantly difficult to reverse. Grinding coffee is a good example of a one-way function: It is easy to grind coffee beans, but it is almost impossible to put back all the tiny pieces together to rebuild the original beans. Symmetric Encryption Uses the same key to encrypt and decrypt data. Quite fast, used in VPN. Key management is a challe...

h Question carries 2 marks. Q.1 If h is any hashing function and is used to hash n keys in to a table of size m, where n<=m, the expected number of collisions involving a particular key x is : (A) less than 1. (B) less than n. (C) less than m. (D) less than n/2. Ans:A Q.2 Let A be an adjacency matrix of a graph G. The th ij entry in the matrix K A , gives (A) The number of paths of length K from vertex Vi to vertex Vj. (B) Shortest ...
