Advanced Encryption Standard

Coroner's Toolkit is a group of basically free tools designed by Wietse Venema and Dan Farmer to be used in the forensic analysis of a UNIX machine. There are several reasons as to why local law enforcement agencies. First, the Coroner's Toolkit is specifically designed to be used in cyber-crime investigation (Farmer & Venema, 2005). This is an exceptionally powerful suite and therefore proper training of UNIX is a major condition in order to manage the Toolkit. Another important reason for…

CFS has been reported in [40]. CFS pushes encryption services into the file system. CFS supports secure storage at the system level through a standard UNIX file system interface to encrypted files. Users associate a cryptographic key with the directories they wish to protect. Files in these directories are transparently encrypted and decrypted with…

of security via an open sea. The communication channel between the secure environments is unsecure. The security goals can be met from time to time using encryption. There are three main types of classical encryption methods or ciphers: transposition, substitution and product ciphers. One of the well known and most widely used asymmetric encryption methods is RSA algorithm. Another technology for hiding data within the contents is ‘Digital Watermarking’. Traditional watermarks may be applied to…

Teslacrypt (a.k.a. EccKrypt ) is a malicious program that encrypts users ' files without the knowledge or consent of the user. It falls into the sub-category of ransomware, a type of malware that encrypts the user 's files using AES encryption and forces them to pay a certain amount of money to decrypt the user 's information, essentially holding a person 's data as hostage. It first emerged around February 2015 along with its counterpart, Alphacrypt, which was released in April 2015, and it has…

message of a more effective system. The news has recently been addressing the ability to break codes much more quickly than in the past because computing power and speed is continually increasing. This poses the question of why should you use an encryption? Think of Moore 's Law; the observation that, over the history of computing hardware, the number of circuits doubles approximately every two years. With this knowledge, the chip for your credit card was created, protecting your information.…

Holmes/Scarpetta Project- The Valley of Fear What discipline was involved? Digital Forensics (cryptology)- The process of encrypting messages and examining digital media forensically to find, analyze, and present facts and opinions. What was the equipment used? The ciphers represent the pages of previous editions of Whitaker's Almanack. The first number represented the page number in the Almanac. The second number, C2, was the column number on the page in the book. The numbers that…

1.1 Overview Cryptography is the science/practice of “writing in secret” (“crypto”= “secret, “graphy” = “writing”). Cryptographic functions are generally defined as algorithms or protocols, rules that govern how data is processed to turn plaintext (unencrypted data) into cipher text (encrypted data) [1]. Cryptography is a method of storing and transmitting data in a form that only those it is intended for can read and process. It is considered a science of protecting information by…

The two methods steganography and cryptography can be used together. Thus it is recommended to use encryption in conjunction with steganography. 3. Motivation This research motivation came after I have studied a Computer Forensics Investigations course at Unitec Institute of Technology. The lecturer provided some useful resources to read and gain more…

Wason Selection tasks What if there are 4 cards on the table: A, K, 2 and 7. On one side of the card there is a number and on the other a letter. You have to decide which cards to turn in order to determine if the following statement is false: If a card has a vowel on one side, then it has an even number on the other side. This is called the Wason Selection task a famous reasoning puzzle (Dawson, Gilovich, Regan, 2002). The answer to this problem is cards A and 7 instead of the most commonly…

The article “Quantum Computer Comes Closer to Cracking RSA Encryption” written by Amy Nordrum, shows that Cryptography needs to be important, because of the fast developing of new technology. In her article Ms. Nordrum tells about computer scientists from the MIT which found a way to crack the RSA (Rivest, Shamir and Adleman)-Code. On the fact, that RSA Encryption is used in all our devices it is quite frightening to know that the government is maybe already using this kind of technology for…
