Swiss e-voting can't count 2,048 ballots after USB keys fail to decrypt them
A Swiss e-voting pilot in Basel-Stadt spectacularly failed to count 2,048 ballots after USB keys refused to decrypt the votes, forcing the canton to suspend its program and launch criminal proceedings. This incident perfectly encapsulates the long-standing debate on the reliability and security of electronic voting, a perennial hot-button issue on Hacker News. It underscores the profound technical and trust challenges inherent in digitizing democratic processes, reinforcing skepticism even among proponents.
The Lowdown
The Swiss canton of Basel-Stadt has suspended its e-voting pilot after a critical failure prevented the counting of 2,048 ballots cast in recent national referendums. Despite efforts from IT experts, three USB keys with the correct decryption codes inexplicably failed, leaving a significant number of votes inaccessible and prompting a swift, serious response from local authorities.
- The e-voting system, primarily for expatriates and disabled individuals, failed to decrypt 2,048 votes collected on March 8.
- Three USB keys, all containing the correct decryption codes, proved ineffective, leading to the uncounted ballots.
- Although the affected votes represented less than 4% of Basel-Stadt's total and did not impact referendum outcomes, the canton deeply regretted the violation of political rights.
- An external analysis has been commissioned, and public prosecutors have initiated criminal proceedings regarding the incident.
- The pilot program has been suspended until the end of December 2026, and confirmation of voting figures has been delayed.
- Other Swiss e-voting systems in different cantons and the national Swiss Post system were reportedly unaffected.
- This isn't Switzerland's first e-voting hurdle; a previous attempt was scrapped in 2019 due to discovered security flaws.
- Separately, one of the referendums successfully enshrined the Swiss National Bank's mandate to supply physical cash into the constitution, despite Switzerland's low cash usage.
This high-profile technical glitch serves as a stark reminder of the complex challenges and inherent risks associated with electronic voting systems, fueling ongoing global debates about their security, reliability, and ultimate suitability for democratic elections.
