"1234" and Birthdays Are the Most Common PINs
Research paper: "A birthday present every eleven wallets? The security of customer-chosen banking PINs," by Joseph Bonneau, Sören Preibusch, and Ross Anderson: Abstract: We provide the first published estimates of the difficulty of guessing a human-chosen 4-digit PIN.

Self-Domestication in Bonobos and Other Animals
Self-Domestication in Bonobos and Other Animals

Cryptanalysis of Satellite Phone Encryption Algorithms
Cryptanalysis of Satellite Phone Encryption Algorithms
From the abstract of the paper: In this paper, we analyze the encryption systems used in the two existing (and competing) satphone standards, GMR-1 and GMR-2. The first main contribution is that we were able to completely reverse engineer the encryption algorithms employed. Both ciphers had not been publicly known previously. We describe the details of the recovery of the...
