An IACR trustee lost a private key, preventing decryption of election results and forcing cancellation and a rerun with added safeguards.
That problem related to the fact that the IACR's bylaws require three members of its election committee to each hold a portion of the cryptographic key material required to jointly decrypt the results. "This aspect of Helios' design ensures that no two trustees could collude to determine the outcome of an election or the contents of individual votes on their own: all trustees must provide their decryption shares," the update explains.
