Physical and System Access Controls
The ExpressVote uses physical and system access controls including lockable doors, tamper-evident seals and access codes. These security safeguards cannot be bypassed or deactivated and alert election officials of unauthorized access while the unit is in storage, transport, preparation and operation.
Verifiable Paper Record
The ExpressVote produces a paper vote summary card that provides voters with the opportunity to review their selections and verify that their vote was recorded accurately before submitting for tabulation. The vote summary card also serves as an audit trail for election officials.
The ExpressVote generates a detailed audit log of all actions and events that have occurred on the unit, which can be printed at any time. Every action and event, including access attempts, access of system functions and errors, is logged and timestamped.
Proprietary Flash Drives
The ExpressVote only accepts certified and approved USB flash drives containing encrypted data signed with the correct, FIPS-compliant, security keys. As such, once an election official installs election programming, it is not possible for a separate device to interface with the ExpressVote in order to overwrite or change the election definition or system firmware.
System Application Controls
The ExpressVote is a purpose-built voting machine. Its system functions are only executable during election events, in the manner and order intended by election officials performing their duties. The system performs a self-diagnostic test at startup, which alerts election officials of errors or changes to the system before any election data is introduced.
Encryption, Hash Validation and Digital Signatures
All data generated during the polls is encrypted and digitally signed. Additional hash validations ensure data integrity remains intact. The ExpressVote also generates a signed data key, ensuring that should unauthorized access of a unit occur, no other units can be affected through data transfer.
