Detailed explanation-1: -Complex algorithms are used to encrypt and decrypt public/private key pairs. The public key authenticates the sender of the digital message, while the private key ensures that only the recipient can open and read it.
Detailed explanation-2: -In public key authentication, the scheme is based on public key cryptography, using cryptosystems where encryption and decryption are done using separate keys, and it is not feasible to derive the decryption key from the encryption key. Each user creates a public/private key pair for authentication purposes.
Detailed explanation-3: -Session keys are sometimes called symmetric keys because the same key is used for both encryption and decryption. The session key is used for only one session.
Detailed explanation-4: -Public Key Certificate, commonly referred to as ‘digital certificate’. Private Key tokens. Certification Authority. Registration Authority. Certificate Management System.
