Cracking DES: Secrets of Encryption Research, Wiretap Politics, and Chip Design - The Electronic Frontier Foundation (EFF) raised the level of honesty in crypto politics by revealing that the Data Encryption Standard (DES) is insecure. The U.S. government has long pressed industry to limit encryption to DES (and even weaker forms), without revealing how easy it is to crack. Continued adherence to this policy would put critical infrastructures at risk; society should choose a different course. To prove the insecurity of DES, EFF built the first unclassified hardware for cracking messages encoded with it. On Wednesday, July 17, 1998 the EFF DES Cracker, which was built for less than $250,000, easily won RSA Laboratory's DES Challenge II contest and a $10,000 cash prize. It took the machine less than 3 days to complete the challenge, shattering the previous record of 39 days set by a massive network of tens of thousands of computers. The research results are fully documented in a book published by EFF and O'Reilly and Associates, entitled Cracking DES: Secrets of Encryption Research, Wiretap Politics, and Chip Design.

Elliptic Curve Cryptosystem (ECC) - Discovered in 1985 by Victor Miller (IBM) and Neil Koblitz (University of Washington) as an alternative mechanism for implementing public-key cryptography. Public-key algorithms create a mechanism for sharing keys among large numbers of participants or entities in a complex information system. Unlike other popular algorithms such as RSA, ECC is based on discrete logarithms that is much more difficult to challenge at equivalent key lengths. The Certicom ECC Challenge offers an opportunity for people around the world to create new methods of attacking the algorithm and exposing any weaknesses. The longer an algorithm stands up to attack the more confidence developers have in its ultimate security.
Evidence Exchange - The first company to provide a system for securely duplicating documents of disparate types so that there is a cryptographically secure link between the copy and the original. This innovative process is called the Secure Digital Photocopier (SDP) and works by taking electronic files of any format and converting them to readable, searchable, printable PDF files, while it fingerprints and digitally notarizes them so they are secure through the entire discovery process.

FreeNet - Freenet lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack. Communications by Freenet nodes are encrypted and are "routed-through" other nodes to make it extremely difficult to determine who is requesting the information and what its content is. Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.

Spread Spectrum Image Steganography (SSIS) - Patent information on SSIS. The Spread Spectrum Image Steganography (SSIS) of the present invention is a data hiding/secret communication steganographic system which uses digital imagery as a cover signal. SSIS provides the ability to hide a significant quantity of information bits within digital images while avoiding detection by an observer. The message is recovered with low error probability due the use of error control coding. SSIS payload is, at a minimum, an order of magnitude greater than of existing watermarking methods. Furthermore, the original image is not needed to extract the hidden information. The proposed recipient need only possess a key in order to reveal the secret message. The very existence of the hidden information is virtually undetectable by human or computer analysis. Finally, SSIS provides resiliency to transmission noise, like that found in a wireless environment and low levels of compression.
