CPP.元A:9 - Explain the principles of security by examining encryption, cryptography, and authentication techniques.Note that a Caesar cipher relies upon an alphabetic shift Standards Alignment View full course alignment CSTA K-12 Computer Science Standards (2011) CPP - Computing Practice & Programming Have students find videos demonstrating these or other advanced encryption methods ask them to describe each algorithm and what causes it to be “hard.”.It's a lot of fun and fairly similar to the frequency analysis tool used in class Vigenère cipher cracker tool on Simon Singh's website.But conversely, should it be required by government regulation? What about for other non-web media, such as mobile phone traffic and television? That it will not be outlawed seems like a settled matter.
Encryption is clearly seen as essential to Internet commercial activity.The government believed they could eventually break cryptography without a back door.) Any back door could probably be exploited by others. Why do you think they stopped urging for this? (Teacher notes: This would weaken the public’s trust in the Internet as an e-commerce vehicle. Additionally, during the 1990s, the US Government was pressuring the computer industry to be allowed to have a “back door” to decryption. The opening pages of Blown to Bits, Chapter 5, discuss a move the government made to try to control encryption in the aftermath of the terrorist attacks of September 11, 2001, but then dropped.Read Blown to Bits (Chapter 5, Secret Bits, pages 161-165, then answer the following questions:.Read this quick overview that put together about How Not to Get Hacked, which summarizes some basic cybersecurity issues and how to prevent them.Nobel prize given for cracking the code of DNA:.Cracking the human genome (NOVA Video):.
