What is public key in PKI?
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity.
How does public key Infrastructure PKI work?
It works by using two different cryptographic keys: a public key and a private key. By using a two-key encryption system, PKI secures sensitive electronic information as it is passed back and forth between two parties, and provides each party with a key to encrypt and decrypt the digital data.
What is a public key infrastructure quizlet?
It is a structure that provides all the necessary components to enable users and entities to communicate in a secure and a predictable manner. A public key infrastructure is a structure that provides all the necessary components to enable users and entities to communicate in a secure and a predictable manner.
What is the Public Key Infrastructure PKI )? List the specific components of the Public Key Infrastructure PKI and explain it?
The components of a PKI include the public key, private key, Certificate Authority, Certificate Store, Certificate Revocation List, and Hardware Security Module. A public key system relies on asymmetric cryptography, which consists of a public and private key pair.
PKI is based on public key cryptography. A trusted “Certificate Authority” creates a key for the organization linked to the digital certificate. When two parties want to communicate with each other, they check the other party’s key against their digital certificate; this establishes they are who they say they are.
What is PKI Geeksforgeeks?
A public key infrastructure (PKI) supports the distribution and identification of public encryption keys, enabling users and computers to both securely exchange data over networks such as the Internet and verify the identity of the other party.
What is the role of a CA in a PKI quizlet?
A CA is an organization or entity that issues and manages digital certificates and is responsible for authenticating and identifying users who participate in the PKI. A CA server can be set up to act as the manager of certificates and the user’s public keys.
What is the difference between centralized and decentralized infrastructures quizlet?
The difference between centralized and decentralized infrastructures is in the location at which the cryptographic key is generated and stored. Cryptographic hardware is required for PKI construction.
