IACR Election Nullified After Trustee Loses Decryption Key

🔐 The International Association of Cryptologic Research (IACR) nullified its 2025 online election after trustee Moti Yung irretrievably lost his private decryption key. The election used the Helios voting system with a strict 3-of-3 trustee decryption scheme, so the missing key meant the system could not compute the final decryption shares or verify the outcome. The loss was an honest human error; the IACR will rerun the vote under a 2-of-3 threshold to permit recovery, and the incident was reported by outlets including Ars Technica and The New York Times.
