A cryptographer and computer scientist, Varia is an expert on the societal impact of algorithms and programs, developing systems that balance privacy and security with transparency and social justice. Mayank Varia might have cracked the conundrum. But there’s a kicker: if that message peddles abuse or misinformation, maybe threatens violence, then anonymity may need to go out the window-the sender needs to be held to account.Īnd that’s the challenge: is there a way to allow people to send confidential, secure, untraceable messages, but still track any menacing ones? If someone leaks the message, it can never be traced back to the sender. It has to be so private, so secret, that they can deny they ever sent it. Here’s the puzzle: Someone wants to send a secure message online.
Indestructible codes, secret notes, encryption, and decryption. A new program could strengthen the security and privacy of WhatsApp, Signal, and other end-to-end encrypted messaging apps and help them better moderate online abuse.Ĭryptographers love an enigma, a problem to solve-and this one has it all.
