AES (Advanced Encryption Standard) has become the encryption algorithm ofchoice for governments, financial institutions, and security-consciousenterprises around the world. The U.S. National Security Agency (NSC) uses itto protect the country’s “top secret” information. RSA is named for the MITscientists (Rivest, Shamir, and Adleman) who first described it in 1977. It is anasymmetric algorithm that uses a publicly known key for encryption, butrequires a different key, known only to the intended recipient, for decryption.i. Differentiate TWO (2) characteristics between AES and RSA.

What Punishment for Webcam Spying is Appropriate?   Microphones, digital cameras, and webcams have many practical and harmless uses. These technologies also can leave you open to spying. For example, one school district used software, which was supposed to track the school-distributed laptops in case of theft, to take photos and scree captures of students. In another instance, a person noticed that when she gave a customer service rep access to her computer, he turned on her webcam without asking for her permission.   Cybercriminals can use spy tools take photos, or record video or audio, without turning on a light or other notification that indicates your camera or microphone is in use. The Flame virus is one way for spy tools to infect your computer. Security experts recommend using a sticker to cover your webcam and inserting a dummy plug in the microphone port when you are not using it. These technologies also allow people to take photos or videos in a public setting and share them…

When you keep passwords in a file, why is hashing passwords better than encrypting the file?

FILL IN THE BLANKS:  Q277: Data Encryption Techniques are particularly used for _______.

Cryptography: Cryptography is a way to keep messages and other data secret. It is the art of writing or solving ciphers. What's a cipher? It's a "secret or disguised way of writing," says the Concise Oxford Dictionary. In the business world, cryptography refers to mathematically based encryption methods that keep data away from the prying eyes of criminals or enemy governments. Today's businesses and governments use what is called "strong" encryption. This type of encryption is created using applied mathematics. Strong encryption was once used solely for military purposes, but in today's information society, encryption is needed for all kinds of uses. Keys are a fundamental component of cryptography, being used in cryptographic operations such as encryption, hashing and signing to provide desirable properties like confidentiality (keeping information secret), integrity (preventing information being altered) or authenticity (verifying who the information came from). One key (public key)…

Intrusions into computers may be prevented thanks to firewalls. The program that filters packets needs a number of different parameters.
