Encryption, Error Correction & Compression

Additional resources (listings and source code) for the articles below can be found here.

A Conversation with Eva Bozoki
Jack Woehr

Network security is a concept whose time clearly has come, and, as Jack finds out this month, DSNT chief scientist Eva Bozoki is in the thick of things, security wise.

The RIPEMD-160 Cryptographic Hash Function
Hans Dobbertin
Bart Preneel
Antoon Bosselaers

Cryptographic hash functions are an essential building block for applications that require data integrity. In this article, our authors propose that the RIPEMD-160 hash function is a secure replacement for MD4 and MD5.

Reed-Solomon Error Correction
Hugo Lyppens

For any number of reasons, Reed-Solomon error correction is commonly implemented in hardware. Here, Hugo presents a highly optimized software implementation of Reed-Solomon error correction, written in C++ and assembly language.

The Zlib Compression Library
Mark Nelson

Mark examines zlib, a library of C routines that can be used to compress or expand files using the same deflate algorithm popularized by PKZIP 2.0.

Windows NT System-Call Hooking
Mark Russinovich
Bryce Cogswell

Mark and Bryce present the design and implementation of NTRegmon, a tool that uses hooking to show detailed information about each and every registry access that occurs on a Windows NT system.

Steganography for DOS Programmers
Alan Johnson

Steganography is a branch of cryptography that deals with concealing messages.

Simulation and Device-Driver Development
Eddy Quicksall
Ken Gibson

To ease the process of writing device drivers for new hardware designs, our authors present a simulation environment. To illustrate its use, they use the sample Adaptec AHA-1540 SCSI miniport driver that comes with the Windows NT DDK.

Simulating the Denver Airport Automated Baggage System
John Swartz

John uses Xlisp to implement a computer simulation of the essential components of the Denver airport automated baggage fiasco, er... system.

Examining Extended MAPI 1.0
Les Thaler

The Extended Messaging Application Programming Interface 1.0, not to be confused with the previous-generation "Simple MAPI," was created to standardize the interfaces between messaging applications and the underlying messaging systems.

Publishing Dynamic Data on the Internet
Lauren Hightower

Allaire's Cold Fusion is a development tool that provides access (via the Web) to any database the web server can access using ODBC. Cold Fusion runs as a multithreaded Windows NT system service and works with any ODBC-compliant database.

Inside Iterated Systems' Fractal Development Kit
Dino Esposito

The Fractal Development Kit from Iterated Systems is a library that makes it possible for you to embed fractal-imaging capabilities into C/C++ Windows and Macintosh applications.

Programming Paradigms
Michael Swaine

Michael looks at paradigms past, focusing this month on spreadsheets.

C Programming
Al Stevens

Users expect standard Windows Help for all applications, no matter how small or how intuitive the procedures. To that end, Al updates a property page dialog-based application to include context-sensitive help for the controls on the dialog pages.

Java Q&A
Clif Berg

Cliff examines how you can use Java to implement a CORBA application that is representative of the way CORBA is likely to be used. In doing so, he revisits the chat application introduced in a previous column.

Algorithm Alley
John Boyer

Heaps are usually implemented via binary trees, with the property that for every subtree, the root is the minimum item. Here, John describes how to implement exceptionally fast "Fibonacci" heaps.

Undocumented Corner
Robert R. Collins

Robert launches an examination of the Intel System Management Mode (SMM), comparing the SMM's RSM instruction to the ICE mode's undocumented LOADALL instruction.

Programmer's Bookshelf
William Stallings
Ron van der Wal

Ron examines Stanley Lippman's Inside the C++ Object Model, while William looks at Peter Wayner's Disappearing Cryptography: Being and Nothingness on the Net.
