Using Des With A Password

Please choose from one (1) of the scenarios below. Note: The scenario that you choose in this assignment will be the one (1) with which you continue for Assignment 2.

Your Answer: b. Two mole s of thios ulfate anion ne e de d to re act

(b.) A prediction is different from both because it describes a result of a hypothesis that must be correct

B – A great example of this dilemma is the iPhone scandal. Many people were distraught when the FBI hacked the iPhone of a criminal. Though this information may be able to criminate someone’s wrongful actions, hacking someone’s information sets a precedent for all the other people in the world who has their information encrypted in the same way. The mere fact for example, a criminal’s iPhone, can be hacked, means that any iPhone can be hacked. It is better to try to access encrypted information legitimately.

• Problem 1: How can we know which error happens and how can we handle it?

Figures: RSA (for key trade) and RC4 (for mass encryption). DES code is accessible yet no

35. Password-cracking can be accomplished by intelligent guessing on the part of the hacker or through the use of an automated __________ attack. Dictionary

Now, we encrypt the message by raising it to the eth power modulo n to obtain C, the cipher text. We then decrypt C by raising it to the dth power modulo n to obtain M again. Formally, we obtain these encryption and decryption algorithms for E and D:

1. Consider 5 processes that need to agree on their joint state. To protect against Byzantine failures, the processes adopted a protocol as described in the slides, in particular, each process broadcasts its own state to all others, assembles the state received from others, and then broadcasts its view of the full state to all others. Suppose that, after this, process 1 receives the information provided below. Identify the process(es) that have Byzantine failure, if any, based on this data. Briefly justify your answer.

Secondly, the next one will be contained of similar session-key as Alice & B0b’s but the difference is it’s obtained by using the B0b- TGS’s secret-key.

A. Assuming Officer Jones only had the information set forth in paragraphs #1 through #4 would he have probable cause for a search warrant? Why or why not?

B. Matching type. Match concepts in column left with the best answers in column right. Write letters only.

Symmetric key encryption is where the key is used to not only encrypt a message but to decrypt it as well. This is also known as conventional and secret key encryption. Symmetric key encryption is rarely used due to the fact that the person who encrypts the information has to get the key to the person who decrypts the information. This is uncommonly used because if the key is intercepted by an unauthorized person, there can

Abstract— Crucial methods are employed to deploy the majority networks to acquire the data. Modern improvements stores, transfer data at higher rate. Traditional methods which provide security to the information. Using single encryption algorithms are more prone to issues and these are implemented without knowing its shortcomings. This proposed algorithms provides new step to avoid shortcomings. We resemble some famous algorithms as follows. Firstly, we create a new algorithms, In order to provide security issue and time constraint of operation. Secondly, We combine AES using multiplexing of keys, Improvement of DES key size and blowfish algorithm, then we encrypt data using the proposed algorithm. This can enhance the security and complicates the Encryption. In this paper we provide both the encryption and decryption that supports in real time application and algorithm has a practical value.5

Which of (a), (b), (c) or (d) is correct in relation to the above argument?
