What is the likelihood of a wall of lava lamps being used as a random number generator in a secure encryption system?
The likelihood of a wall of lava lamps being used as a random number generator in a secure encryption system is very low. While lava lamps can produce random patterns, they are not considered a reliable or secure method for generating encryption keys. Advanced cryptographic algorithms and hardware-based random number generators are typically used for secure encryption systems.

Explain the evaluation criteria for Advanced Encryption Standard (AES)?
The evaluation criteria for the Advanced Encryption Standard (AES) included security, performance, and flexibility. Security was assessed based on the algorithm's resistance to various cryptographic attacks, while performance evaluated the efficiency of encryption and decryption processes across different platforms. Additionally, flexibility considered the ability to adapt the algorithm to various key lengths and operational modes. Ultimately, AES was selected for its robust security and efficiency in a wide range of applications.
Which is an example of a technical control information assurance?
An example of a technical control in information assurance is the implementation of firewalls. Firewalls monitor and filter incoming and outgoing network traffic based on predetermined security rules, helping to prevent unauthorized access to or from a private network. This control is crucial for protecting sensitive information and maintaining the integrity of systems. Other examples include encryption and intrusion detection systems, which also help safeguard data and ensure secure communications.
What do many cyber criminals do to avoid detection?
they utilize anonymization methods such as: wifi stealing (being sure to alter the MAC address, or clear the router's logs afterwards), out-of-the-country VPN use, SSH tunneling, TOR (must use encryption, as some exit nodes are monitored), proxy tunneling (server based, NOT web proxys). These are all commonly used methods, and many of them can be combined, often with the additional use of secure encryption and the clearing of logs made anywhere work is done. due to the ambiguity of the question I here detail only general methods used.
What is the most popular symmetric encryption system used over the Web?
The most common hybrid system is based on the Diffie-Hellman key exchange, which is a method for exchanging private keys using public key encryption. Diffie-Hellman key exchange uses asymmetric encryption to exchange session keys. These are limited-use symmetric keys for temporary communications; they allow two entities to conduct quick, efficient, secure communications based on symmetric encryption, which is more efficient than asymmetric encryption for sending messages. Diffie_Hellman provides the foundation for subsequent developments in public key encryption. It protects data from exposure to third parties, which is sometimes a problem when keys are exchanged out-of-land.
Identify the primary cryptographical techniques employed when producing cipher text?
The primary cryptographical techniques used to produce ciphertext include substitution, where characters or bits are replaced with others based on a key, and transposition, which rearranges the order of characters without altering them. Additional techniques include symmetric key encryption, where the same key is used for both encryption and decryption, and asymmetric key encryption, which uses a pair of keys (public and private). Hash functions may also be used for integrity verification, though they do not produce reversible ciphertext. Together, these techniques enhance data security and confidentiality.
Is asymmetric encryption The key are math?
Yes, asymmetric encryption relies on mathematical principles, specifically involving key pairs: a public key and a private key. The public key encrypts data, while the private key decrypts it, ensuring that only the intended recipient can access the information. The security of this method is based on complex mathematical problems, such as factoring large primes or solving discrete logarithms, which are computationally difficult to reverse. This makes asymmetric encryption a robust method for secure communication.
In asymmetric encryption the keys are mathematically?
In asymmetric encryption, the keys are mathematically related but serve different purposes: one is a public key, which can be shared openly, and the other is a private key, which is kept secret. The encryption process uses the public key to encrypt data, while the decryption process requires the corresponding private key. This relationship ensures that only the holder of the private key can decrypt messages encrypted with the public key, providing a secure means of communication. The mathematical foundation typically involves complex algorithms based on number theory, such as RSA or elliptic curve cryptography.
How is encryption commonly used?
Data encryption the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign governments. It is also now used increasingly by the financial industry to protect money transfers, by merchants to protect credit-card information in electronic commerce, and by corporations to secure sensitive communications of proprietary information. All modern cryptography is based on the use of algorithms to scramble (encrypt) the original message, called plaintext, into unintelligible babble, called ciphertext. The operation of the algorithm requires the use of a key. Until 1976 the algorithms were symmetric, that is, the key used to encrypt the plaintext was the same as the key used to decrypt the ciphertext.
What is one of the most effective file encryption software?
One of the most effective file encryption software available online is Sophos Free Encryption. It is based off their pay to use program SafeGuard PrivateCrypto.
What is public key encryption and why is it getting popular?
Public key encryption is the process of encoding messages in such a way that eavesdroppers or hackers cannot read the message but that authorized parties can. It uses two keys at the same time, a private key that is only known to your computer and a public key that your computer gives to another computer wanting to communicate with the former. Without both keys, the messages cannot be read. Both keys are based on prime numbers making this system extremely secure and popular because essentially there is an infinite number of prime numbers available, meaning a nearly infinite possibilities for keys.
What is encryption and its daily life example?

How intuitive is encryption software?
Encryption software is intuitive to a certain degree limited by the software designer, since after all, the software was written by a person and encrypts based on a set range of parameters.
What the security of public key asymetric cryptography is based upon?
The security of asymmetric cryptography depends on the difficulty - of determining the private key given the public key. For example: an asymmetric encryption algorithm might rely on the difficulty of factoring a very large number into two prime factors. If the cost of computational power and time to perform the factoring exceeds the value of the encrypted information, then the encryption would be considered sufficiently secure for practical purposes. An asymmetric encryption algorithm may also rely on the difficulty of computing discrete logarithms. Both the "factoring products of primes" and "calculating discrete logarithms" approaches to recovering the "private" key of an asymmetric encryption are assumed to rely on the difficulty of brute force attacks. Sometimes algorithms are improperly implemented, the keys are too short, or an inherent weakness is found that allows faster recovery of the key by restricting the key space that must be searched. In these cases, the security of the asymmetric encryption may be significantly less than would be otherwise assumed - i.e. it may be possible to break the encryption fast enough to make it worth the effort.
What are the Encryption strategies for preventing laptop data leaks?
Most businesses will choose IT-administered stored data protection, based on file/folder encryption, full-disk encryption or some combination thereof. File/folder encryption is also selective, but encrypts files automatically, based on defined attributes like file location (e.g., folder), file type (e.g., spreadsheets) or source application (e.g., everything Excel touches). For general purpose computers, the other popular approach is to simply encrypt everything stored on a physical disk or a logical volume. The goal is to ensure that nothing is ever written to storage without being encrypted. That includes not only sensitive user data, but also application and operating system files.
