Are CSPRNGs non deterministic?
Cryptographically Secure Pseudorandom Number Generators (CSPRNGs) are a critical component in the field of cybersecurity, particularly within the realms of classical cryptography and stream ciphers. To address the question of whether CSPRNGs are non-deterministic, it is essential to consider the definitions, functions, and characteristics of CSPRNGs, as well as their distinction from true random number
Under what conditions does the entropy of a random variable vanish, and what does this imply about the variable?
The entropy of a random variable refers to the amount of uncertainty or randomness associated with the variable. In the field of cybersecurity, particularly in quantum cryptography, understanding the conditions under which the entropy of a random variable vanishes is important. This knowledge helps in assessing the security and reliability of cryptographic systems. The entropy

Explain the exponential growth in the number of steps required when simulating a non-deterministic Turing machine on a deterministic Turing machine.
The exponential growth in the number of steps required when simulating a non-deterministic Turing machine on a deterministic Turing machine is a fundamental concept in computational complexity theory. This phenomenon arises due to the inherent differences between these two computational models and has significant implications for the analysis and understanding of time complexity in various
