N.S.A. Able to Foil Basic Safeguards of Privacy on Web (Published 2013)
The National Security Agency is winning its long-running secret war on encryption, using supercomputers, technical trickery, court orders and behind-the-scenes persuasion to undermine the major tools protecting the privacy of everyday communications in the Internet age, according to newly disclosed documents. The agency has circumvented or cracked much of the encryption, or digital scrambling, tha

Enigma/Paper Enigma - Franklin Heath Ltd Wiki
Although the Enigma cipher as a whole is quite complex (it's complexity is comparable to modern cryptographic algorithms) the individual transf ormations within it are relatively simple. In fact, they are simple enough that you can decipher an Enigma message with just a paper model. Our model is three-dimensional, to illustrate the wiring of a real Enigma machine. It needs only common household ite

Homomorphic Encryption Breakthrough - Schneier on Security
Homomorphic Encryption Breakthrough Last month, IBM made some pretty brash claims about homomorphic encryption and the future of security. I hate to be the one to throw cold water on the whole thingâ€”as cool as the new discovery isâ€”but itâ€™s important to separate the theoretical from the practical. Homomorphic cryptosystems are ones where mathematical operations on the ciphertext have regular effect
