Transport Layer Security
Transport Layer Security (TLS), the successor to Secure Sockets Layer (SSL), is a security protocol used to communicate between client and server. It establishes an encrypted communication channel to secure data. Although Arista switches use TLS, the terms TLS and SSL are used interchangeably in this document.
Following are the two main components that TLS uses for authentication of identity before any communication starts.
An SSL certificate is required to establish a secure connection between the client and server. The certificate includes all of the details which are necessary for authentication. Cryptographic keys are used to provide a secure channel of communication. TLS uses two cryptographic keys: a private key known only to the server and a public key embedded in the certificate. The keys are used to validate the certificate.
