Communications Security and privacy are not new concepts. At 400 BC the Greeks used a transposition cipher. Individual letters were written on a long thin sheet of paper and then wrapped around a cylinder. The diameter of the cylinder was the key to find out the original letter. In this context, I find it necessary to give some definitions of related vocabulary in this field. -Plain text or PT is the original message that we need to send. Usually we do not want others to be able to

Missing Chart Encryption Encryption is a method of programming data for security so that it appears to be random data. Only the people sending and receiving the information have the key to decrypt the message, which will put it back into its original form making it readable. The only people with the key are the people who are intended to read the message. Not many people know what encryption is. I took a survey of twenty students and asked two questions. The first question I asked was do you

conventional and public key cryptography. PGP is a hybrid cryptosystem. PGP then creates a session key, which is a one-time-only secret key. This key is a random number generated from the random movements of your mouse and the keystrokes you type. This session key works with a very secure, fast conventional encryption algorithm to encrypt the plaintext; the result is ciphertext. Once the data is encrypted, the session key is then encrypted to the recipient's public key. This public key-encrypted session

months and was finally released in 2003 with limitations and restrictions using the computers and phones and later Kevin fought it out with the court decision and later was allowed to use the web and computers. Kevin became popular after getting the public attention through media, he gave many interviews and was seen in many TV shows, he wrote few books which were bestselling and later he even started a consulting computer security company and was paid to hack the companies which he loved to core, at

BTC contains a string of combination of numbers and letters. This string which ranges from 26-35 characters is named as Bitcoin address which is unique and is recreated at every transaction. (Bitcoinwiki, 2015) By utilizing combination of public and private key cryptology, the senders can transfer

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and

Where to Get the Official Kali Linux Images ISO Files for Intel-based PCs In order to run Kali “Live” from a USB drive on standard Windows and Macintosh PCs, you’ll need a Kali Linux bootable ISO image, in either 32-bit or 64-bit formats. If you’re not sure of the architecture of the system you want to run Kali Linux on, on Linux or OS X, you can run the command uname -m at the command line. If you get the response, “x86_64”, use the 64-bit ISO image (the one containing “amd64” in the file name);

The most important and significant challenge in the big data is to preserve privacy information of the customers, employees, and the organizations. It is very sensitive and includes conceptual, technical as well as legal significance. Any collected information about a person, when combined with other sets of data, can lead to the finding of persons secret and private information. “ As big data expands the sources of data it can use, the trustworthiness of each data source needs to be verified, and
