homomorphic encryption

Numberphile interviews cryptographer Ron Rivest about end-to-end verifiable voting. He explains how homomorphic encryption and receipts let a voter confirm their ballot was counted without being able to prove how they voted to anyone else.

Tom Caputi presents the design of native encryption for ZFS at the OpenZFS Developer Summit, including design decisions and how authentication uses checksum fields.

John Oliver's Last Week Tonight segment on encryption and the Apple versus FBI dispute after San Bernardino. It explains the stakes of weakening encryption and ends with a fake Apple ad about iPhone vulnerabilities.

A satirical 'honest' government ad from The Juice Media about Australia's 2018 Assistance and Access anti-encryption bill. It lays out in blunt terms what the law would let authorities do.

A 2016 House Judiciary Committee hearing on encryption, held during the Apple and FBI iPhone dispute. It features testimony from Apple, the FBI and outside experts including Susan Landau, and runs over five hours.

A five-minute CGP Grey explainer arguing that a phone is effectively an extension of your mind, and that any backdoor or master key into encrypted devices will inevitably be abused or leaked. It frames the encryption debate as locks that are either unbreakable or absent.

MC Frontalot's nerdcore song "Secrets From The Future" (2007), about secrets not staying hidden once future technology can break today's encryption.

A short Princeton CITP video describing cold boot attacks, where encryption keys remain in DRAM after power loss and can be recovered. It covers the attack against disk encryption such as BitLocker, FileVault and TrueCrypt.

A clip of Australian Prime Minister Malcolm Turnbull saying the laws of Australia prevail over the laws of mathematics, regarding encryption. The audio is quiet in the second half.

MinutePhysics explains Shor's algorithm, showing how a quantum computer factors large integers by finding the period of a number modulo N. It walks through the modular arithmetic and number theory that give the exponential speedup over classical factoring, and why this threatens encryption.

A WiebeTech marketing demo of HotPlug, a device that moves a running computer onto battery or another power source so it can be transported without shutting down.

A short explainer on the history and mechanics of public key cryptography and the Diffie-Hellman key exchange. It uses a mixing-paint-colors analogy to show how two parties can agree on a shared secret in public.

Moxie Marlinspike speaks at Next Generation Threats 2014 about the challenges of encrypted communication and how Signal addresses them. He also draws on American action movies as narrative for secure communications.

A 2018 VICE News Tonight interview with Apple CEO Tim Cook, in which he discusses privacy as a core company value, the Facebook breach, and Apple's iCloud arrangement in China.

PBS Infinite Series explains how Shor's algorithm lets a quantum computer break RSA encryption, building on earlier episodes about cryptography and the math of quantum computers. It works through the idea step by step.

Tom Scott visits Cloudflare's San Francisco office to show the wall of lava lamps whose camera feed is used as a source of entropy for random number generation. It is a short explainer on how this helps secure internet encryption.

Veritasium tells the story of the XZ backdoor, how a patient attacker became maintainer and nearly compromised SSH on Linux systems. It also covers free software history and how encryption in SSH works.
