Cryptanalysis

intended recipient. While cryptography is the science of securing data, cryptanalysis is the science of analyzing and breaking secure communication. Classical cryptanalysis involves an interesting combination of analytical reasoning, application of mathematical tools, pattern finding, patience, determination, and luck. Cryptanalysts are also called attackers…

In a general level the functions of scrambling and unscrambling messages can be called encryption and decryption, thought depending on which technique is used there exists a more specific vocabulary. The opposite of cryptography is cryptanalysis, the science of breaking codes and ciphers. One of the earliest cryptanalytic techniques is frequency analysis, a process which was first described by “the philosopher of Arabs, al-Kindi” in the ninth century. The basis of this technique is the…

Government Code and Cypher School, a British code-breaking organization. During World War II, Turing was a leader in wartime code-breaking especially the German ciphers. He worked at Bletchley Park, where he made five major advances in the field of cryptanalysis, including the bombe, an electromechanical device used to help decipher German Enigma encrypted codes and signals. Turing’s contributions to the code-breaking process didn’t stop. He also wrote two papers about mathematical approaches…

of the encryption. For example: with the old pkzip encryption method. In this case if you had any of the unencrypted files in the archive, you could use that to obtain the key to break the rest. Plain text attack is the other type of attack for cryptanalysis the place that the attacker have the samples of the plaintext as well as encrypted version (known while cipher text version), he then incorporate the use of these to present more private information after computing the secured source key.…

Blowfish. I. INTRODUCTION Cryptography is an enormous topic, for it has several aspects. Professionals who decide to study this field have different reasons. The beginning of cryptography was to assist military and for political purposes. Thus, cryptanalysis field has been found…

Have you ever heard of Spy-Free or Spy-Proof Emails? Most of people do not know well about the importance of privacy in their email and even they realize its importance, they are not sensitive to it. Now, the world’s best-known email providers Yahoo, and Google put in a great deal of effort to encrypted email system. They will introduce a new secure email system in the near future. However, some experts bring up several problems of encrypted mail. Christopher Soghoian, a security and privacy…

Who Was the Zodiac Killer? Although the Zodiac Killer was a real man, he remains a myth in American history. He is one of the few serial killers who remains at large. The police were never able to identify him, therefore, he was never caught. His crime spree began back in the 1960’s in the San Francisco Bay area and continued into the 1970’s. There have been many speculations as to his identity, but it has never been confirmed. The Zodiac Killer began his killing spree on December…

Alan Turing, The Man’s Mind Of Enigma Of Computer Technology, Changed Modern Society, And The Outcome Of WWII In December 1941 Nazi Germany, and Japan declared war on the United States, and though this was a groundbreaking event for everyone, it didn’t stop one man from London. During this given time of war there would be a hero from not the actual war itself, but emerge inside the mind of that person. Thus it impacted everything that was going on, and not just the war, but technology itself.…

by analyzing the sound emitted by the CPU when decrypting the message. This method of attack is called Acoustic Cryptanalysis attack. The three researchers are Daniel Genkin, Eran Tromer and Adi Shamir (co-inventor of RSA). They extract 4096-bit key by recording noise from the laptop device when decrypting using a smartphone device placed near the laptop. Using the Acoustic Cryptanalysis attack, they were able to get a long RSA key in less than one…

PopCo, by Scarlett Thomas, was written in 2004 in England. Published by Harcourt, Inc. PopCo is a novel which leaves a reader with puzzles to solve after reading and a thirst for knowledge. This fictional novel covers a wide range of subjects spanning from World War II to buried treasure. This novel has the power to influence young minds with its clever use of bouncing around from one subject to the next; this novel truly makes a reader think. There are many clear influences on the author which…
