Abstract
This paper develops an efficient pseudo-random number generator for validation of digital communication channels and secure disc. Drives. Simulation results validates the effectiveness of the random number generator.
Highlights
Digital data while transmission over communication channels becomes corrupted because of Inter Symbol Interference (ISI), Co-Channel Interference (CCI), multipath-fading etc
This paper develops an efficient pseudo-random number generator for validation of digital communication channels and secure disc
We show that disk drives can provide physical randomness for seeding generators for cryptographic random number, but they are targets to specific attacks, exploiting their use and special characteristics, leading to specific entropy requirements of the disk
Summary
Digital data while transmission over communication channels becomes corrupted because of Inter Symbol Interference (ISI), Co-Channel Interference (CCI), multipath-fading etc. Previous data of the random number generator are difficult to store securely, because an attacker could read, and in some point in the future restore earlier states (together with any possible local authentication tags) with the help of specialized tools (spin stand), and so force the generation of the same random sequence as earlier. This may cause repeated nonces, of which recurring use of the same encryption keys, and so forth, that is, loss of security. These will provide confidence in the generated random numbers for their users, and tools for developers of embedded random number generators in testing and evaluation of designs
