041168 `The Colossus of Bletchley Park'
AJ Sale, IEE Review, March 1995 pp 55{59
The author describes a project to reconstruct the Colossus, an early computer
used at Bletchley Park for correlation attacks on the Lorentz Geheimschreiber. This
used hundreds of thyratrons to simulate the rotor wheels and counters to keep track of
pattern matches. This machine would process intercepts at 5000 characters per second
| the speed at which the paper tape could be fed | and could break a key setting
in 2-3 days. Although its secrecy meant that it had no direct impact on subsequent
computing history, it had an indirect e ect in that it showed Turing and others that
digital machines with thousands of valves could be made to work reliably.
041169 `Coding for Distributed Computation'
LJ Schulman, Info Theory 94 p 28
The author discusses the impact e ect of noisy links in a computer network when
it comes to performing a distributed computation. This paper may be consider when
looking at the hook up problem in secure networks.
041170 `MultiSix: How it Improves Interoperability in a Multi-Vendor
Network'
S Scudamore, ACM SIGSAC v 13 no 1 (Jan 95) pp 12{16
This paper describes DEC's trusted network architecture which supports DNSIX,
CMW, trusted X, Trusted TCP/IP and Trusted NFS.
041171 `Netscape opens Internet to cards'
S Smith, Cards International (11/1/95) p6
Netscape's new secure browser, together with its commerce server, can now process
credit card transactions through six acquiring banks.
041172 `Internet: Zielscheibe fur Hacker'
D Sticharz, Datenschutzberater v 19 no 2 (15/2/95) pp p{4
The author describes some recent security incidents on the Internet, including an
assault on the San Diego Supercomputer Center in December which used IP address
spoo ng. Attacks on routers are also described and references are given to a number
of CERT advisories.
041173 `Bolero trade steps'
STalmor, The Banker (Feb 95) pp 72{75
The EC's Bolero project, to develop and pilot an EDI system for bills of lading,
is due to nish in July. As these bills carry value as well as information, they are
digitally signed, with secret keys managed using smartcards; there is also a central
registry, whose main purpose is to stop banks obtaining all the trading information of
payees. Perceived bene ts to traders include cutting errors and processing costs, while
banks are concerned to integrate bills of lading with letter of credit systems.
041174 `Faster, ever faster'
ITredinnick, International Security Review no 87 (Winter 94/5) pp 17{18
ISDN lines may nd an important application in video surveillance; they increase
the frame rate from 1 per 3 seconds to 4{6 per second.
041175 `A signature scheme using a compiler'
K Usuda, M Mambo,TUyematsu, E Okamoto, JW-ISC 95 pp 111{119
The authors describe a signature scheme for virus protection: it reassures the
programmer that his executable programs are signed without being infected with a
virus.
