Back in 1998, Tim May warned us of the "Four Horsemen of the Infocalypse": "terrorists, pedophiles, drug dealers, and money launderers." I tended to cast it slightly differently. This is me from 2005: Beware the Four Horsemen of the Information Apocalypse: terrorists, drug dealers, kidnappers, and child pornographers. Seems like ... Read More

There's a serious debate on reforming Section 230 of the Communications Decency Act. I am in the process of figuring out what I believe, and this is more a place to put resources and listen to people's comments. The EFF has written extensively on why it is so important and ... Read More

This just in: We are pleased to announce the factorization of RSA-240, from RSA's challenge list, and the computation of a discrete logarithm of the same size (795 bits): RSA-240 = 12462036678171878406583504460810659043482037465167880575481878888328 966680118821085503603957027250874750986476843845862105486553797025393057189121 768431828636284694840530161441643046806687569941524699318570418303051254959437 1372159029236099 = 509435952285839914555051023580843714132648382024111473186660296521821206469746 700620316443478873837606252372049619334517 * 244624208838318150567813139024002896653802092578931401452041221336558477095178 155258218897735030590669041302045908071447 [...] The previous records were RSA-768 (768 bits) in ...

Interesting research: "TrojDRL: Trojan Attacks on Deep Reinforcement Learning Agents": Abstract:: Recent work has identified that classification models implemented as neural networks are vulnerable to data-poisoning and Trojan attacks at training time. In this work, we show that these training-time vulnerabilities extend to deep reinforcement learning (DRL) agents and can ... Read More

The NSA has released a security advisory warning of the dangers of TLS inspection: Transport Layer Security Inspection (TLSI), also known as TLS break and inspect, is a security process that allows enterprises to decrypt traffic, inspect the decrypted content for threats, and then re-encrypt the traffic before it enters ...

Really interesting research: TPM-FAIL: TPM meets Timing and Lattice Attacks, by Daniel Moghimi, Berk Sunar, Thomas Eisenbarth, and Nadia Heninger. Abstract: Trusted Platform Module (TPM) serves as a hardware-based root of trust that protects cryptographic keys from privileged system and physical adversaries. In this work, we per-form a black-box timing ... Read More

Technologists and policymakers largely inhabit two separate worlds. It's an old problem, one that the British scientist CP Snow identified in a 1959 essay entitled The Two Cultures. He called them sciences and humanities, and pointed to the split as a major hindrance to solving the world's problems. The essay ... Read More
