Lisa Bock covers common cryptographic concepts necessary to securely exchange data. These concepts include key exchange, digital signatures, certificates, certificate authority, and public key infrastructure.
- [Instructor] There are some common…cryptographic concepts and terms…network administrators should understand.…These include key exchange, digital signatures,…certificates, certificate authority,…and public key infrastructure.…Key exchange is securely exchanging…the shared secret key between parties.…Digital signature is a value generated…using public key encryption…that verifies data's origin and integrity.…
A certificate authority is a trusted third party…in a hybrid crypto system that both parties trust.…The certificate authority issues certificates.…We use a certificate authority…when using Secure Socket Layer…to communicate securely on the web.…Examples include Symantec, Verisign, and DigiCert,…which are companies that provide certificate services.…When completing transactions on the internet,…we need to use someone's public key,…and we need to be able to trust…that the key is from the entity…from whom we receive it.…
A certificate is a set of descriptive data…that provides proof of identity,…and is a way to ensure that you can trust…
