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
What is the CSPRNG unpredictability based on?
Cryptographically Secure Pseudo-Random Number Generators (CSPRNGs) are fundamental components in the realm of cybersecurity, particularly in the context of classical cryptography and stream ciphers. The unpredictability of CSPRNGs is a critical attribute that ensures the security of cryptographic systems. This property is based on several key factors, including the initial seed value, the deterministic algorithm

What are the key differences between True Random Number Generators (TRNGs), Pseudorandom Number Generators (PRNGs), and Cryptographically Secure Pseudorandom Number Generators (CSPRNGs)?
True Random Number Generators (TRNGs), Pseudorandom Number Generators (PRNGs), and Cryptographically Secure Pseudorandom Number Generators (CSPRNGs) are critical components in the field of cybersecurity, especially within the domain of cryptography. Each of these generators serves to produce random numbers or sequences, but they do so in fundamentally different ways, with distinct properties and use cases.
