Description: This course on Public Key Infrastructure (PKI): Architectures, Standards, and Trust Mechanisms provides a comprehensive understanding of how digital trust and secure communication are established in modern information systems. It begins with the fundamentals of symmetric and asymmetric cryptography, introducing the pivotal role of PKI in enabling authentication, confidentiality, integrity, and non-repudiation. Learners explore PKI architecture, key concepts, and core trust models, including certificate authorities, registration authorities, certificate policies (CP), and certification practice statements (CPS). The course covers key management, certificate lifecycle, distribution mechanisms, and validation through certificate chains and revocation methods.Advanced modules delve into access control models (DAC, MAC, RBAC), digital signatures, and secure communication protocols such as VPNs, Kerberos, and challenge–response authentication. Emerging concepts like zero-knowledge proofs (ZKPs), biometrics integration, and decentralized trust architectures—including hub-and-spoke and four-corner models—are also examined. Learners gain insights into mitigating business and technology risks, securing e-commerce platforms, and architecting resilient, connected systems.By the end of the course, participants will have a solid grasp of PKI standards, cryptographic principles, and trust mechanisms essential for designing and managing secure, scalable, and interoperable digital infrastructures.The course also emphasizes practical applications of PKI in real-world scenarios, fostering skills in implementing, auditing, and maintaining secure digital ecosystems across diverse organizational environments.
