    A Survey on Satellite Network Security Ma Ting G0902682F mati0004@ntu.edu.sg Abstract Security is an important concern in satellite multicast communications. Due to its highly dynamic broadcast nature, the multicast systems generally have a large number of terminal members with frequent join-leave characteristic. Therefore, the satellite networks face significant security challenges, such as eavesdropping and Denial of Service (DoS). What is more, satellite systems are...

Cryptography, derived from the Greek word κρυπτοσ meaning hidden, is the science of creating and decoding secret messages whose meaning cannot be understood by others who might intercept the message. In the language of cryptography, the message you are trying to send is called the plaintext; the message that you actually send is called the ciphertext. Unless your adversaries know...

    1) How does the public key cryptography work? Explain in detail? 1. Public-key, what it is Public-key refers to a cryptographic mechanism. It has been named public-key to differentiate it from the traditional and more intuitive cryptographic mechanism known as: symmetric-key, shared secret, secret-key and also called private-key. Symmetric-key cryptography is a mechanism by which the same key is used for both encrypting and decrypting; it is more intuitive because of its similarity...

First line in the code creates a dialogue box that asks for a text to encode. Submitted text is then reversed. Next the %windir%\notepad opens up an instance of Notepad to print the results after waiting for 1 second. Then a function is written that encodes the text by advancing each character by 3 letters.

    Primecoin gets its name from the unique algorithm used to mine it. Bitcoin miners use a hashcash algorithm, which acts as a proof-of-work to verify legitimate Bitcoins and eliminate duplicates. Primecoin miners, on the other hand, look for Cunningham chains, long strings of prime numbers. As it turns out, increasingly enormous prime numbers are exceedingly valuable for RSA encryption, which allows two users to pass secret messages back and forth, and has been the standard for confidential...
