Abstract: ABSTRACT “HYBRID CRYPTOGRAPHICALLY SECURE RANDOM BIT GENERATION SYSTEM AND METHOD USING MULTI-SOURCE ENTROPY” The present invention relates to a hybrid cryptographically secure random bit generation system (100) and method (200) for generating cryptographically secure random bitstreams. The system (100) comprises a physical entropy sensing unit (102) having a multi-axis MEMS accelerometer, a financial stochastic input acquisition unit (104) for deriving stochastic financial data from financial time-series data, and an operating-system entropy acquisition unit (106). A chaotic state processing unit (108) uses the stochastic financial data to update a three-dimensional state vector and generate a dynamically evolving chaotic-state output. An entropy fusion unit (110) combines the chaotic-state output, physical entropy and operating-system entropy to generate hybrid entropy. An entropy conditioning unit (112) cryptographically conditions the hybrid entropy to generate conditioned seed material for initializing or reseeding a cryptographic random bit generation unit (118), thereby generating the cryptographically secure random bitstream.
