Analysis of Physical Random Number Properties Generated by Semiconductor Super Lattices

摘要

The proerties of fast physical random-number that is generated based on room-temperature chaotic oscillations in weakly coupled superlattices are investigated in detail, including the balansability, the linear complexity, the cross-correlation, and auto-correlation characteristics. Experimental and simulating reasults indicate that the ratio between the number of ones and zeros is 10001:10000 and the correlations are excellent and the linear complexity is good, which proves the physical random-number generated ased on room-temperature chaotic oscillations in weakly coupled superlattices can be used in the information secure communications effectively.
