The Homework Library (HL) is a database of solved problems.

HL materials are not original and are therefore made available for the sole purpose of studying and learning.
**Misuse of HL materials is strictly forbidden.**

The HL was created for students who need immediate help, and in many cases you can find step-by-step
explanations on how to solve a problem or examples of proper writing, including the use of citations,
references, bibliographies, and formatting.

If you don’t find what you are looking for within our HL database, please reach out to one of our tutors
and schedule a tutoring session.

1. Warm-up: cryptographic hash functions and guessing games, 5 marks Recall that the parity of an integer N refers to the property of N being even or odd. Suppose Bob is the proud owner of a random number generator that generates truly random integers of arbitrary size and is completely tamper-pr...

Problem 3 — RSA primes too close together, 18 marks) This problem explores a difference of squares approach to factoring an RSA modulus due to Fermat, and hence also known as Fermat factorization. Fermat’s idea was to attempt to find a representation of an integer n as a difference of...

Programming Problem Problem 6 — Password attack on an authenticated encryption scheme Overview. Suppose Bob has designed his own authenticated encryption scheme, using the hash then-encrypt paradigm, with AES-128 in CBC mode for encryption, and SHA1 for the key derivation function and mess...

No programs, no calculators in this problem that spoil the fun! Working inZ3[x]: (a) Show that f(x) =x⁴+x−1 is irreducible (b) How many elements does the finite field F=Z3[x]/(f(x)) contain? (c) Find the multiplicative inverse of 2x²−x−1 in F.

Explain why the trivial protocol for Alice and Bob to compute f(x,y)=x⨁y, where x,y∈{0,1}, satisfies the definition of secure 2-party computation. The trivial protocol is that Alice sends x to Bob, Bob computes f(x,y) and sends it to Alice.

Error propagation is often an important consideration when choosing a mode of operation in practice. In this problem, you will analyze the error propagation properties of an arbitrary block cipher in various such modes; note that these properties are independent of the cipher used. a)Suppose Ali...

Use the field and subject filters to browse through Homework Library solutions that pertain to your areas of interest. We are adding new content to the library on a daily basis, so check back from time to time. If you'd like us to post solutions in a subject we don't yet have content for, let us know - we'd like to hear from you!

The solutions will include information such as the original question and sometimes a preview of the solution itself. When you are ready to purchase a solution just click on it and it will be yours.

There is no time limit. Once you purchase a solution you'll have access to it for as long as your registration on the site remains valid. If you can log into your account, you can view any purchased solutions.
