Quantum cryptography

communicate. Cryptography is the way we can transmit secret messages so that only the person it is meant for can understand it. The art of coding and decoding messages has progressed immensely through time, and has become increasingly difficult to break with the use of technology. Cryptography’s evolution has transformed the computing world into what it is today, and this comes with positive and negative effects. As long as people have secrets and want to transmit them, cryptography will…

using PGP encryption, and its limitation. What is PGP encryption and how does it work? PGP is an abbreviation for “Pretty Good Privacy.” It is a hybrid encryption since PGP is a combination of some best features of both original and public key cryptography. If you encrypt the plaintext using PGP, it firstly compresses the plaintext and by data compression, modem transmission time and disk space are saved. Also, data compression strengthens cryptographic…

encryption. There are some basic information about this type of cryptography will be reviewed. Then, symmetric cryptography advantages and problems will be covered. After that, comparison on several symmetric algorithms are discussed. These algorithms are DES, Triple DES, AES, RC2, RC4, RC6, and Blowfish. Keywords—Cryptography, Symmetric Encryption, Encryption, Decryption, DES, Triple DES, AES, RC2, RC4, RC6, Blowfish. I. INTRODUCTION Cryptography is an enormous topic, for it has several…

A COMPARITIVE STUDY OF NEAREST NEIGHBOUR ALGORITHM AND GENETIC ALGORITHM IN SOLVING TRAVELLING SALESMAN PROBLEM Ajaz Ahmed Khan Electronics and communication department SSGI FET Bhilai, India ajz70277@gmail.com Mrs. Himani Agrawal Electronics and communication department SSGI FET Bhilai, India Abstract—In this paper, we have used two algorithms, i.e. the Nearest Neighbor algorithm and Genetic Algorithm to solve the Travelling Salesman problem. The Travelling Salesman…

Introduction In the present times when we look at the Intelligence agencies, the first thing that strikes our mind is secrecy – the services must have the benefit of operational secrecy. Because the services work clandestinely and the nature of their tasks requires them to fulfil their obligations in secret, they are at odds with the principle of open society. In cases of these agencies, there arises a conflict between there operational need of secrecy and the democratic objective of…

In Kim, Kipling melded the genuine work of the Indian Survey Department with anecdotal English intelligence operations, which utilized Asian specialists with cryptonyms like The Mirza or E5, to develop a mixture association profoundly occupied with counterintelligence activities on the boondocks and inside the Indian subcontinent. Other than Colonel Creighton who, as Control, is normally English, Kipling's legends are all Asian: the Afghan stallion merchant, Mahbub Ali; the Indian master of…

Forward: When Edward Snowden revealed that the NSA was spying on us in 2012, I expected people to be outraged. I expected a massive public backlash that would lead to reform. By and large, the public’s reaction has been underwhelming. For one reason or another, government surveillance is a topic that many people don’t know about or don’t talk about. I’ve talked to people about surveillance before, and many of them were unaware of key details about it. Some were simply unaware that government…

The Aegis Secure Key 3.0 has military grade full disk AES 256-bit XTS hardware encryption and is FIPS 140-2 Level 3 validated. You unlock the drive by entering your 7-16 digit PIN before you connect it to your device that way hackers cannot use software on your device to capture your password, and it automatically locks when you unplug it. If an incorrect password is typed 20 consecutive times all the data and the encryption key are erased. It is also dust and water resistant as well as a wear…

When it comes to password security, we are faced with a serious conundrum. While we want to remember the password, we still need to practice safe security with a good one. The trouble with the easier to remember passwords is that they are highly insecure. What can you do to combat this problem? When you are using uppercase and lowercase letters, symbols and numbers to compensate, you can use what is known as a passpoem to resolve the problem of remembering. As Marjan Ghazvininejad and Kevin…

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…
