Real-Arithmetic Sketched Eigensolvers for Symmetric Matrices

In this work, we develop sketched variants of subspace iteration and TraceMIN, called sSI and sTraceMIN, for real symmetric eigenvalue problems by combining basis whitening with the sketched Rayleigh-Ritz (sRR) procedure. The nonsymmetric projected matrix in sRR may have nonreal eigenpairs, leading to complex arithmeti...

UQ-Vote: Consensus-Authorized Threshold Decryption for End-to-End Verifiable Elections

End-to-end verifiable electronic voting requires more than encrypted ballots and a published tally. Auditors also need a consistent election transcript, and trustees need a clear rule for deciding when decryption is allowed. Existing systems often combine threshold tallying with a bulletin board. However, the condition...
