electronic voting

Security firm Trail of Bits has published a detailed explainer on the cryptography behind electronic voting, arguing that even strong encryption cannot replace paper ballots. The post walks through how cryptographic protocols can verify votes and protect secrecy, while emphasising that end-to-end verifiability and voter-verifiable paper records remain essential to trustworthy elections.

Brazil's 2026 elections' first round saw voters in Rio de Janeiro still lining up after 7pm, with reports of queues, arrests and problems with electronic voting machines in the state. National coverage is also focused on the second-round campaign, with Flávio Bolsonaro touring all regions of the country while President Lula skipped the North. Outlets including CNN Brasil, Agência Brasil and R7 are following developments closely.
