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.
Digital Certificates: Protocols, Management, and Security
"Digital Certificates: Protocols, Management, and Security" "Digital Certificates: Protocols, Management, and Security" offers a comprehensive exploration of the foundational technologies, operational strategies, and evolving standards underpinning digital certificate ecosystems. Beginning with the mathematical and cryptographic principles behind asymmetric cryptography, the book meticulously details the structure and use of X.509 certificates and the major standards and protocols that define identity and trust on the modern internet. Readers gain a deep understanding of how digital certificates assure authenticity, enable secure communication, and support critical infrastructure from SSL/TLS and code signing to IoT and document validation. The book thoroughly examines the certificate authority ecosystem and diverse trust models essential to Public Key Infrastructure (PKI), providing expert insights into CA operations, cross-certification, governance policies, certificate pinning, and incident response protocols. An entire section is devoted to the lifecycle management of certificates—encompassing secure key generation, enrollment workflows, policy enforcement, automated renewal, and revocation—at both enterprise scale and within cloud-native environments. Attention is given to operational resiliency and integration with modern DevOps, incident detection, and high-availability architectures. Addressing both current threats and future challenges, the book delivers practical frameworks for threat modeling, mis-issuance mitigation through transparency logs, and quantum-safe migration strategies. Legal, regulatory, and compliance considerations are discussed in a global context, with guidance on data privacy, incident accountability, and cross-jurisdictional trust. Concluding with coverage of cutting-edge developments—such as decentralized PKI, blockchain approaches, privacy-preserving architectures, and automated management for edge computing—the book is indispensable for security professionals, architects, and policymakers seeking to master the complexities and drive the future of digital trust infrastructure.
Rethinking Public Key Infrastructures and Digital Certificates
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.
