Digital certificates, a new form of electronic ID, is a new security technology that establishes a digital identity for a person or a company and guarantees the authenticity of information delivered over the Web or via email. This title explores all of the critical aspects of digital certificates in detail and provides basic information on cryptography. The CD-ROM contains a complete system for controlling access to information on the Internet based on digital certificate technology.

Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications. They are already widely used for authenticating and encrypting email and software, and eventually will be built into any device or piece of software that must be able to communicate securely. There is a serious problem, however, with this unavoidable trend: unless drastic measures are taken, everyone will be forced to communicate via what will be the most pervasive electronic surveillance tool ever built. There will also be abundant opportunity for misuse of digital certificates by hackers, unscrupulous employees, government agencies, financial institutions, insurance companies, and so on.In this book Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. Such certificates function in much the same way as cinema tickets or subway tokens: anyone can establish their validity and the data they specify, but no more than that. Furthermore, different actions by the same person cannot be linked. Certificate holders have control over what information is disclosed, and to whom. Subsets of the proposed cryptographic building blocks can be used in combination, allowing a cookbook approach to the design of public key infrastructures. Potential applications include electronic cash, electronic postage, digital rights management, pseudonyms for online chat rooms, health care information storage, electronic voting, and even electronic gambling.

This IBM® Redbooks® publication is the first in a series of five books that relate to the implementation and management of digital certificates that are based on a public key infrastructure. Digital certificates play a major role in the protection of data communications and their use continues to grow. This Redbooks publication includes the following chapters: - Chapter 1, "Digital certificates overview" on page 1 provides an overview of digital certificates. It describes their purpose, gives a high-level overview of how they are created and their relationship to keys and encryption, and how they can be deployed into an organization. - Chapter 2, "Digital certificate management considerations" on page 19 describes choices and their possible effects to consider for setting up and organizing the infrastructure and processes to be effective in your environments. - Chapter 3, "Introducing z/OS PKI Services" on page 27 describes how the IBM z/OS® PKI services can provide you with a cross-platform solution to manage your digital certificates and build a strong solution that uses established qualities of service. After you read this IBM Redbooks publication, we suggest that you progress to the following: - z/OS PKI Services: Quick Set-up for Multiple CAs, SG24-8337 Your comments are appreciated.
