Rainbow and ERUCES Team Up on High-Assurance Data Security

Strategic Agreement Combines The FIPS-140 Level 3 Certified Hardware Security Module with Emerging Security Engine Software for Innovative Tamper-Proof Security

Networld+Interop, Spring 2002, LAS VEGAS — May 7, 2002 ? Rainbow eSecurity, a Rainbow Technologies, Inc., (Nasdaq: RNBO) company and a leading solutions provider of digital content and transaction security, and ERUCES, a security software company that allows organizations to implement the highest level of security possible, have teamed up to integrate the ERUCES Tricryption Engine and Rainbow’s CryptoSwift HSM to provide an exceptional hardware- and software-based solution for tamper-proofing corporate-critical data.

The ERUCES and Rainbow solution ensures that stored data is not tampered with, and that the data remains unchanged and intact. Customers using this integrated solution gain a high degree of assurance that the confidential information in their corporate databases is completely protected, leaving hackers and malicious unauthorized users inside the organization attempting to access the data with unreadable text. In addition, users gain a high degree of security through the CryptoSwift HSM’s FIPS-140-1 Level 3 Certification.

“Today’s customers not only demand high-assurance security but high-assurance data and content integrity,” said David M. Lynch, vice president of marketing, Rainbow eSecurity. “The CryptoSwift HSM together with the ERUCES Tricryption Engine gives these customers the higher security they need with the content protection they demand.”

“By offering CryptoSwift HSM with our Tricryption Engine, our customers get an unsurpassed level of tamper-proof corporate content, whether its business-critical data or mission-critical applications,” said Bassam Khulusi, president and CEO, ERUCES. “We’re pleased to partner with Rainbow on this next-generation content protection security solution.”

The integrated Rainbow and ERUCES solution will be available this summer.

About CryptoSwift HSM
Rainbow’s CryptoSwift HSM is certified by the National Institute of Standards and Technology (NIST) for FIPS 140-1 Level 3 and is ideal in high-assurance environments, such as banking and financial services, and healthcare and government applications.

The CryptoSwift HSM shields a certificate authority’s (CA) root key or the online certificate status protocol (OCSP) server’s signing key within a tamper-active circuitry built directly into the HSM. The hardware security module processes all digital signatures for high-end/high-assurance security. When the data is backed up, all key materials are encrypted before they leave the HSM, which helps users defeat physical attacks through detection alerts and early responses. The CryptoSwift HSM provides true on-board Random Number Generation, Java-based key and device management software, and a tamper-active circuitry that easily secures sensitive keying information. For performance and scalability, multiple CryptoSwift HSM accelerators can be installed to adequately scale performance for the organization?s entire Web server infrastructure.

Rainbow eSecurity’s CryptoSwift family of eCommerce accelerators have won more major industry awards for excellence than any other SSL acceleration solution, including a prestigious “Well-Connected Award” for best SSL accelerator and “Editor’s Choice Award” for best internal SSL accelerator from Network Computing, a “Blue Ribbon Award” from Network World as the industry’s top cryptographic accelerator and two American Electronics Association (AEA) High Tech Awards for “Innovative Product/Technology” in 2000 and 2001.

ERUCES is a security software company that allows industry leaders to implement the highest level of data security possible. With the Eruces Tricryption Engine, confidential information in storage is completely protected, leaving hackers and malicious unauthorized users with unreadable text.
