M5.9 Lab: AES and RSA Encryption and Decryption

Introduction

Encrypting data is essential to ensure safe data transmission. Both symmetric and asymmetric algorithms are used to encrypt the data. In this activity, you will use the open-source CrypTool to analyze the popular AES and RSA algorithm.

Instructions

You will use the open-source Cryptool-2 to perform cryptanalysis and evaluate the algorithm used for encryption with a known ciphertext. Follow the steps given in the following document:

AES and RSA Encryption and Decryption [PDF, 103 KB] (See Attached File )

Next, submit a 2 to 3-page paper discussing the following:

How useful is a tool like Crytool2 for Cryptologists?
What were your alternatives for decoding this ciphertext if you didnt have the key?
What are some recommendations you could make when using ciphertext and cryptoanalysis?
How is AES different from RSA?

Factoring polynomials

Please help factor these polynomials. I would also appreciate if you can discuss briefly how you arrived at the answer, and provide tips on how to work on similar problems in the future. Thanks

1.) x2 – 15x + 54

2.) x2 – 8x – 9

3.) x2 – 10x – 11

4) x2 – 6x – 16

Standard deviation

The Acme Battery Company has developed a new cell phone battery. On average, the battery lasts 60 minutes on a single charge. The standard deviation is 4 minutes.

Suppose the manufacturing department runs a quality control test. They randomly select 7 batteries. The standard deviation of the selected batteries is 6 minutes. What would be the chi-square statistic represented by this test?
