1. You are Alice. You have agreed with your friend Bob that you will use the Diffie-Hellman public-key algorithm to exchange secret keys. You and Bob have agreed to use the public base g = 3 and public modulus p = 809. You have secretly picked the value SA = 17. You begin the session by sending Bob your calculated value of TA. Bob responds by sending you the value TB = 291. What is the value of your shared secret key?
2. A particular cipher is implemented by combining the ASCII representation of plaintext characters with pseudorandom bytes (eight-bit binary strings of 1s and 0s) using the XOR function. In the process of encrypting a message, a character in the plaintext, a capital H, is XORed with the pseudorandom byte 10111100.
a. What is the ciphertext (in binary form) generated by the encryption of the character D? (show your work.)b. How is the plaintext for this encrypted D recovered? (show your work.)
3. An organization has 300 members. It is desired that each member of the organization be able to communicate securely with any other member, without any other member being able to decrypt their messages. How many unique keys are required if:
a. The organization uses a symmetric cipher.b. The organization uses an asymmetric cipher.
If you receive the ciphertext message YPHDCRPBEQTAA, decrypt to recover the plaintext. What is the decryption function, and the recovered plaintext? What type of cipher is this?
SLE, ARO, and ALE, behavioural biometric technology, Enterprise Information Security Policy, Issue Specific Security Policy, System Specific Security Policy, firewalls protect network, creating a DMZ during firewall implementation, use of SSL to se..
ESSAYS a special requirement mentioned back in milestone 1, Jack millss wished the system to have "state-of-the-art-maybe some biometric device which can be used in office and at home easily and cheaply.

Identify and describe the organizational authentication technology and network security issues
Analyze security requirements and prepare a security policy.
Cross-talk, and other forms of interference are a significant issue in any communications infrastructure. Compare and contrast how this problem would manifest for analog data transmitted
Write a 1-2 page document that describes the options for improving the FTP environment described. Make a recommendation for a single solution for the FTP environment.
Decrypt the cipher-text c = 12 by using secret key sk = (p, q) = (11, 13), where te corresponding public key is pk = (N, e) = (143, 13).
Give the security levels Top SECRET,SECRET,CONFIDENTIAL, and UNCLASSIFIED (order from highest to lowest), and catergories A, B,C, specify what type of access (read,write, both or neither) is allowed in each of the following situations .
You were given the following plaintext and cipertext, and you are needed to find key used by them. plaintext: Using Vigene table, find key used by them to encrypt the message.
Decrypt to recover the plaintext. What is the decryption function, and the recovered plaintext? What type of cipher is this?
