Industry Leaders Infineon Technologies and PGP Corporation Announce Collaboration to Increase and Enhance Security Options

Neubiberg, Germany and Palo Alto, CA – April 22, 2008 – Infineon Technologies AG (FSE/NYSE: IFX), a leading provider of security semiconductors and enterprise security software, and PGP Corporation, a global leader in enterprise data protection, today announced that they have begun collaboration across a range of technical and business areas. The two companies will initially provide a combined solution to allow Trusted Platform Module provisioning and management in conjunction with PGP® Whole Disk Encryption. The PGP® Encryption Platform and Infineon’s recently-announced Trusted Computing Management Server (TCMS) software are complementary robust and mature security solutions. The combined solution will enable enterprises to comprehensively manage their data protection systems with Trusted Platform Modules (TPMs). TPMs are security microcontrollers present in most enterprise-class PCs deployed today. Until the advent of TCMS, these TPMs could not be used effectively due to lack of centralized manageability. PGP Whole Disk Encryption, one of the applications of the PGP Encryption Platform, utilizes a PC’s integrated TPM chip to add a second authentication factor to a basic passphrase. Enterprise customers can now leverage the TCMS infrastructure to centrally provision, manage, and back up TPM-based keys as a first step to a comprehensive deployment of desktop encryption. Together, Infineon’s and PGP Corporation’s products meet the most critical enterprise requirements of recovery, logging, provisioning, and policy management. Infineon is a leader in TPM integrated circuits worldwide and has the largest installed base of TPMs currently deployed. In addition, the Infineon Professional Package, which provides the operating system-specific software components to support TPMs, is pre-installed by numerous top-tier PC manufacturers throughout the world. Infineon’s TPM Professional Package V3.5 is TPM-vendor-neutral, a core capability of the product. Infineon will supply client software for Intel’s version 1.2 TPMs. “PGP Corporation is one of the strongest brands in the enterprise data protection market, and we are very pleased to be working together with PGP Corporation on future projects,” said Paolo Cocchiglia, Vice President, ASIC Design and Security (ADS) business unit of Infineon Technologies North America. The unique PGP Encryption Platform is the cornerstone of PGP product offerings. The PGP Encryption Platform provides a single, leveraged, extensible architecture that reduces IT operational costs and eliminates the duplicative tasks, systems, training, and support issues that plague other approaches. Unlike point solutions that address a single threat or cobbled-together product suites that lack integration, the PGP Encryption Platform delivers an integrated encryption framework across the broadest range of encryption applications. “We are excited to be working with Infineon, a leading TPM hardware and software vendor, to meet the challenges of managing keys and security policies across the ever-increasing breadth of security solutions being deployed,” said Phil Dunkelberger, President and CEO of PGP Corporation. “Besides offering our joint customers a unique and powerful security solution, this announcement validates the PGP Encryption Platform strategy by demonstrating its extensibility across a broad range of data protection technologies.” About PGP Corporation PGP Corporation is a global leader in email and data encryption software for enterprise data protection.
