Public Key Infrastructure

What is PKI?

Public Key Infrastructure (PKI) is a framework of policies, procedures, hardware, software, and people that enables the creation, distribution, management, and revocation of digital certificates and public-key encryption. In India, PKI plays a critical role in securing online transactions, digital signatures, and identity verification under initiatives like Digital India and e-governance services such as Aadhaar authentication and Income Tax filing. It is widely used by enterprises, banks, and government portals to secure email, VPNs, web traffic (via SSL/TLS), and code signing. PKI relies on Certificate Authorities (CAs) to issue and validate certificates, ensuring that the public key belongs to a legitimate entity. For students and professionals in cybersecurity, networking, and information technology, PKI is a core topic often tested in certifications like CEH, CISSP, and Indian government exams (e.g., UPSC, SSC) that include computer awareness sections. Understanding PKI helps prevent eavesdropping, tampering, and impersonation in digital communications, making it foundational to modern internet trust models. With India's increasing digitization, PKI adoption continues to grow, especially in banking (e.g., net banking, UPI), legal e-filing, and cloud services.
