A password generator creates a 10-character case-sensitive alphanumeric (a-zA-Z0-9) password keyed by pseudo-random number generator that has deterministic output based on a 32-bit seed (e.g., a 32-bit integer) provided by the user. How many passwords are possible? If it takes .0001 seconds to check a password, what will the average length of time be for a successful brute force attack?
Bob has designed a secure login system for the student portal of the Xiamen University of Technology (XUT). In Bob's design, a two-factor authentication method is used for verifying the authenticity of the user. A brief description of the design is provided below. For the two-factor authentication, the followings are required: • Factor 1: a user first required to provide a secret password, • Factor 2: the user then needs to provide the correct answer to a security question. To securely store the user password in the system, Bob has used state-of-the-art encryption algorithm, Advanced Encryption Standard (AES), to encrypt the user password and stored the encrypted password in the system database. For securely signing in to the system: the user needs to provide his/her user ID and the corresponding password. This information will be transmitted to the system over a secure communication channel. Upon receiving this information, the system will: o locate/retrieve the corresponding…
An early attempt to force users to use less predictable passwords involved computer-supplied passwords. The passwords were eight characters long and were taken from the character set consisting of lowercase letters and digits. They were generated by a pseudorandom number generator with 215 possible starting values. Using the technology of the time, the time required to search through all character strings of length 8 from a 36-character alphabet was 112 years. Unfortunately, this is not a true reflection of the actual security of the system. Explain the problem.
Question 1 Study the scenario and complete the question(s) that follow: Ceasar Cipher The Caesar Cipher technique is one of the earliest and simplest method of encryption technique. It's simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example with a shift of 1, A would be replaced by B, B would become C, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials. 1.1 Write a Ceasar cipher algorithm in such a way that a character D is changed to N. Derive the encryption of the other characters accordingly. 1.2 Based on your algorithm, what will be the encrypted code of the message “my mother is not home". End of Question 1
A cipher suite is a choice of algorithms for key exchange, authentication and encryption to be used together in TLS. Cipher suites are specified by an abbreviation such as the following: “ADH-DES-CBC-SHA”. Search online and find one example of a cipher suite used in TLS 1.3. Write the name of the cipher suite; then, for each component, write what the abbreviation stands for and for which cryptographic task that algorithm is used in that suite.
What exactly is a "single point of failure" in terms of passwords?
A system allows a user to choose a password with a length of one to eight characters, inclusive. Assume the selection of any password is equiprobable. If an attacker performs a dictionary attack using a computer that can test 10,000 passwords per second, determine the average time in hours for the attacker to find a password for each of the following conditions. Password characters must be numbers (“0” to “9”). Password characters may be any alphanumeric characters (“A” through “Z,” “a” through “z,” and “0” through “9”). Password characters may be any ASCII characters from 1 to 127, inclusive.
The Caesar Cipher Algorithm was introduced in Week #1. Encryption is the act of encoding a message with the intent of allowing only authorized people the knowledge of how to read that message. An encrypted message can be decoded, allowing the secured content to be read after decryption. Recall that the Caesar Cipher uses alphabets as the primary source of information but shifted a certain number of letters to the left or right as a key to create the encrypted data. The Caesar Cipher is easily hacked because of the simple technique used to build the key that encrypts and decrypts the data. In this lab, the key is the number of alphabets shifted, and the direction is always toward the increasing alphabetical order. This provides 26 ways of encrypting a message and therefore makes it easier to be hacked by guessing the key within the range of 0 - 25. Write the function caesar_hack( ) that takes three parameters: a Caesar Cipher encrypted message, an alphabet list, and the original…

Suppose the parameters for an instance of the RSA cryptosystem are N = 17363, e 5, and d = 10253. %3D Decrypt the message y = 8244. Decrypt the message y = 12241.
This is case sensitive. The government hired you to decrypt the encrypted message. The hacker used a Denial of Service attack, which resulted in a massive blackout of the government websites' internet services. The only way to get things back to normal is to decode the message left by the hacker. The message has been decoded as follows: 01010011 01110100 01110101 01000100 01111001 00100000 01001000 01100001 01110010 01100100 00100000 00100110 00100000 01101101 01100001 01001011 01100101 00100000 01110011 01110101 01110010 01100101 00100000 01010100 01101111 00100000 01110000 01000001 01110011 01010011 00100000 01110100 01101000 01100101 00100000 01000101 01101101 01010000 01101111 01110111 01100101 01010010 01101101 01100101 01101110 01110100 00100000 01010100 01100101 01100011 01101000 01101110 01101111 01101100 00110000 01100111 01101001 01100101 01110011 00100000 01110011 01010101 01100010 01101010 01100101 01100011 01110100 00101110
