PKI-Based Digital Signatures: The Cornerstone of Digital Trust
In today's increasingly digital world, ensuring the authenticity, integrity, and non-repudiation of electronic documents and communications is paramount. Digital signatures , often referred to as the digital equivalent of a handwritten signature, serve this purpose. Unlike physical signatures, which can be easily forged or tampered with, digital signatures are generated through complex mathematical algorithms that operate on the backbone of Public Key Infrastructure (PKI). This makes PKI-based digital signatures a critical component of digital trust. How PKI-Based Digital Signatures Work At the core of PKI-based digital signatures lies a pair of cryptographic keys: a public key and a private key. The private key, which is securely held by the signer, is used to create the digital signature. The public key, on the other hand, is freely distributed and is used by recipients to verify the signature's authenticity. The digital signing process can be broken down i...
