Weakness (CWE)
CWE-1241: Use of Predictable Algorithm in Random Number Generator
The device uses an algorithm that is predictable and generates a pseudo-random number.
More detail
Pseudo-random number generator algorithms are predictable because their registers have a finite number of possible states, which eventually lead to repeating patterns. As a result, pseudo-random number generators (PRNGs) can compromise their randomness or expose their internal state to various attacks, such as reverse engineering or tampering.
How to prevent it (1 mitigation)
-
Architecture and Design, Implementation
It is highly recommended to use a true random number generator (TRNG) to ensure the security of encryption schemes. Hardware-based TRNGs generate unpredictable, unbiased, and independent random numbers because they employ physical phenomena, e.g., electrical noise, as sources to generate random numbers.
