Cryptography Questions
A public key infrastructure (PKI) is a system of technologies, policies, and procedures that enable the secure exchange of information over a network. It involves the use of cryptographic techniques to manage and distribute digital certificates, which are used to verify the authenticity of entities such as individuals, organizations, or devices. PKI provides a framework for secure communication, authentication, and encryption, ensuring confidentiality, integrity, and non-repudiation of data exchanged between parties.
