Abstract: ABSTRACT The present disclosure relates to electronic voting apparatus with cryptographic audit capabilities. The apparatus (100) conducts electronic voting using a hardware random number generator (102) incorporating an avalanche diode (104) that generates entropy from thermal noise throughout a polling period. A microprocessor 108 computes a hash chain link by combining each vote record with a hash digest of the sequentially preceding vote record. A truncated hash derived from the hash chain link is printed alongside a candidate identifier on a paper slip via a printer (106), creating a voter verifiable paper audit trail. After poll closure, the microprocessor 108 selects audit stations using entropy accumulated from the hardware random number generator (102). Post-election verification confirms correspondence between paper slips and stored electronic vote records using the truncated hash at the selected audit stations, ensuring tamper-evident logging and statistically rigorous, hardware-driven audit selection.
