Prompt

System architecture diagram for a secure online voting system. Voters authenticate with government-issued identity verification and MFA, then receive a ballot. Core services should include ballot generation, vote casting, tallying, and audit verification. Encrypt votes end-to-end, store encrypted ballots in a write-once ledger, and keep a separate audit log. Use HSM/KMS for key management and enforce strict RBAC for election officials. Provide monitoring, rate limiting, and anomaly detection.

Key flows

Show all (3)
  • Voting flow: voters authenticate with MFA, receive a ballot, and submit an encrypted vote that the Vote Casting Service signs and stores in the immutable ballot ledger.
  • Audit flow: every access and vote event is written to the audit log with signatures, enabling independent verification and anomaly detection.
  • Tally flow: encrypted ballots are processed by the tally service using HSM-protected keys, and final results are published to the public repository.
