What is able to identify users with public key infrastructure?
I'm not certain of the intent of the question but it sounds like what is being asked is how you can know the actual identity of someone from their public key - i.e. how you can know that the public key really belongs to the person it purports to belong to. PKI (public key infrastructure) is one way to establish with reasonable certainty that a key really belongs to the entity that is claimed. PKI uses a system of Certificate Authorities (CA) and Registration Authorities (RA). At the top of the chain is the Registration Authority that everyone trusts. Users register their public keys with the RA. CA's also register their certificates withe the RA along with proof that they are who they say they are. CA's are repositories of public keys that the public can access. They sign the keys with their own certificates vouching for the identity of the public key owner. The identity of the CA may, in turn, be vouched for by an RA or higher CA who sign the certificate of that particular CA.
What are Four general categories of schemes for distribution of public key?
The four general categories of schemes for the distribution of public keys are: Key Directories: Centralized databases where public keys are stored and can be retrieved by users. Web of Trust: A decentralized model where users validate each other’s keys, building a trust network based on personal relationships. Public Key Infrastructure (PKI): A framework that uses Certificate Authorities (CAs) to issue digital certificates, verifying the authenticity of public keys. Peer-to-Peer Distribution: Methods that allow users to share public keys directly with each other, often using secure channels or protocols.
Why Google is not concerned with distributing public key?
Google is not overly concerned with distributing public keys because they utilize established protocols and systems, such as HTTPS and Certificate Authorities, to manage secure communications. These protocols ensure that public keys are verified and distributed securely, minimizing the risk of impersonation or man-in-the-middle attacks. Additionally, Google implements advanced security measures, such as certificate pinning and the use of its own infrastructure, to enhance trust in their public key distribution. This layered approach helps ensure the integrity and confidentiality of user data without the need for direct public key distribution.
The combination of a public key and a private key is known as a?
This is known as RSA encryption. Encryption involving a public and private key combination is known as asynchronous cryptography, as opposed to synchronous cryptography. It is also known as public key cryptography. RSA is an algorithm that may be used (but there are others that can be used), in public key cryptography. (A key pair)
What is the process for RSA decryption using a public key?
RSA decryption using a public key involves the recipient using the public key provided by the sender to decrypt the encrypted message. The recipient uses the public key to raise the ciphertext to the power of the public exponent, and then takes the result modulo the public modulus to obtain the original plaintext message.

What does PKI stand for?
It stands for Public Key Infrastructure. It has to do with security and data encryption.
The use of certificate authorities to associate public keys with certain users is known as?
PKI or Public Key Infrastructure
What element of the public key infrastructure is used to issue digital certificates?
certificate authority
How can one get a PKI certificate?
One can receive a PKI certificate, or a public-key infrastructure certificate, is by digitally signing and publishing the public key bound to a given user.
Where can one find information on public key infrastructure?
The concept of a public key infrastructure is quite complicated. It is basically a combination of hardware, software, policies, procedures and people which combined together manage a digital certificate. It is explained in some detail on Wikipedia.
Digital certificates are transported over the Internet and verified using?
PKI (Public-key Infrastructure)
8 How does Public Key Infrastructure protect information assets?
Public Key Infrastructure (PKI) in an integrated system of software, encryption methodologies, protocols, legal agreements, and third-party services that enables users to communicate securely an protect information assets.
In a large environment which part of the public key infrastructure PKI is responsible for maintaining a certificate database?
Certificate Server (CS)
How does Public Key Infrastructure (PKI) operates?
Public Key Infrastructure (PKI) operates by using a combination of hardware, software, policies, and procedures to manage digital certificates and public-key encryption. It involves a trusted Certificate Authority (CA) that issues digital certificates to verify the identity of entities, allowing secure communication. Users generate a pair of keys: a public key, which is shared widely, and a private key, kept secret. PKI ensures the integrity, authentication, and non-repudiation of data through cryptographic techniques, enabling secure transactions over unsecured networks.
