In two elements of the nation, Moscow and the area of Nizhny Novgorod, individuals had an choice to vote electronically. Their votes have been recorded on Exonum-based blockchain system created by Moscow’s Division of Data Applied sciences with the assistance of Kaspersky Lab.
In response to Meduza’s findings, votes had been encrypted utilizing the TweetNaCl.js cryptographic library. This gives a deterministic algorithm, which means that with related enter knowledge, the system generates the identical cryptographic key, which is used for each encoding and decoding the vote.

That contradicted Meduza’s report, which stated it’s attainable to decode any vote utilizing the identical cryptographic keys.
The division’s press workplace didn’t reply to CoinDesk’s request for remark by press time.
Kaspersky Lab’s press consultant, Olga Bogolyubskay, instructed CoinDesk the corporate has nothing so as to add to the official remark by the division, however did say it has been offering “knowledgeable assist to the Moscow Division of Data Know-how,” together with different corporations.
“We’ve got experience and vital expertise in guaranteeing the safety and transparency of mass on-line voting utilizing blockchain applied sciences by way of our Polys platform,” Bogolyubskaya added.
Meduza’s report is simply the most recent safety concern with the voting system. The Division of Data Applied sciences reported Friday that an “statement node” had been attacked whereas the constitutional vote was underway. Nonetheless, in response to unbiased elections observers in Russia, there isn’t any technical method to connect with the blockchain from the surface, because it ran completely on the division’s servers.
