Industry Embraces Microsoft’s Internet Digital Signature Initiative

SAN FRANCISCO, March 12, 1996 — More than 40 companies today announced support for Microsoft Corp.’s initiative to allow customers to validate the identity and integrity of software downloaded over the Internet. Using industry-standard digital signature and certificate formats, a user can ensure that a piece of software has not been tampered with or modified, and also can uniquely identify the publisher. This reassures the user of the source of the software and protects against the spread of malicious code over the Internet as Web pages incorporate more active software.

“Being able to identify software under this program is critical to the growth of the Internet,”
said Philippe Kahn, co-founder and chairman of Starfish Software Inc.
“It will significantly reduce fraud and virus propagation.”

Digital Signature Authentication Infrastructure

VeriSign Inc. and GTE will provide the underlying infrastructure for the digital signature program. Under the program, developers obtain digital certificates that verify who they are. Then, using cryptographic techniques, they apply them to the code. Developers are free to use any development tool to create programs, then add their digital signatures before releasing the program to the Internet. VeriSign and Microsoft have been working on a proposal to create a set of policies for identifying software developers and the accompanying formats of the digital certificates and signatures.


Code authentication is an exciting new application for digital signatures and Digital ID
™s, which will ensure the source and the integrity of downloadable software,”
said Stratton Sclavos, president and CEO of VeriSign Inc.
“We are pleased to have worked with Microsoft on this initiative to define an open industry model for securing software distribution.”

Open Industry Standard

The digital signature proposal provides support for several industry standard techniques including X509 certificates and PKCS #7 signature blocks.
“The World Wide Web Consortium encourages the introduction of digital signatures to provide assurances of authenticity of documents on the Web,”
said Tim Berners-Lee, W3C director.
“This is clearly of great importance for executable code on the Web. We will be working toward a common system for signed code and registration of signatories.”

Microsoft is working with W3C to make this an open, cross-platform standard. With this program, all languages (such as the Microsoft® Visual Basic®
programming system, the
Visual C++®
development system set and Java ) will be supported and all applications will be able to use the authentication services available on ActiveX
™
. A program overview, proposed specifications and tools were published at the Professional Development Conference – Building Internet Applications this week in San Francisco.

Strong Industry Support

Many vendors have stepped forward to support the digital signature proposal. Vendors of ActiveX Controls (formerly called OLE Controls), vendors of shrink-wrapped software, and standards bodies all recognize the need for an industry-standard digital signature initiative.

“One of the challenges to providers of high-performance, enhanced components for the Internet is to ensure the integrity of those components as they get distributed over the Internet,”
said Bob Wolf, president of Sheridan Software Systems Inc.
“We at Sheridan are therefore very excited about Microsoft’s initiative to ensure security and integrity through digital signing. We plan to make digital signing an integral part of all our future enhanced-component products for the Internet.”

“Corel Corp. encourages the acceptance of and is planning to support the Microsoft digital signature initiative as an industry standard for the purpose of facilitating the authentication of executable code transferred over local networks and the Internet,”
said Eid Eid, vice president of software at Corel Corp.

“The code-signing initiative proposed by Microsoft is an important step that will help grow the component software industry,”
said Frank Grossman, president of NuMega Technologies Inc.
“We will be supporting this with our error detection and advanced debugging tools for Windows® .”
