Here’s an IDEA-variant with a 128-bit block length. While I think it’s a great idea to bring IDEA up to a modern block length, the paper has none of the cryptanalysis behind it that IDEA had. If nothing else, I would have expected more than eight rounds. If anyone wants to practice differential and linear … Read More “The IDEA Encryption Algorithm with a 128-bit Block Length” »
Remember back in 2013 when the then-director of the NSA Keith Alexander claimed that Section 215 bulk telephone metadata surveillance stopped “fifty-four different terrorist-related activities”?

This is … Read More “Basaaly Moalin: The One "Terrorist" Caught by Section 215 Surveillance” »

It’s a common fraud on sites like eBay: buyers falsely claim that they never received a purchased item in the mail. Here’s a paper on defending against this fraud through basic psychological security measures. It’s preliminary research, but probably worth experimental research. We have tested a collection of possible user-interface enhancements aimed at reducing liar … Read More “Defending Against Liar Buyer Fraud” »
At a CATO surveillance event last month, Ben Wittes talked about inherent presidential powers of surveillance with this hypothetical: “What should Congress have to say about the rules when Barack Obama wants to know what Vladimir Putin is talking about?” His answer was basically that Congress should have no say: “I think most people, going … Read More “Accountability as a Security System” »
Late last year, in a criminal case involving export violations, the US government disclosed a mysterious database of telephone call records that it had queried in the case. The defendant argued that the database was the NSA’s, and that the query was unconditional and the evidence should be suppressed. The government said that the database … Read More “US Law Enforcement Also Conducting Mass Telephone Surveillance” »
