Answer Posted / Reetika Yadav
Key exchange is a process that establishes shared secret keys between two parties to secure communication. In the context of Wi-Fi and Transport Layer Security (TLS), here's how it works:n
1. Pre-shared Key (PSK) in WPA/WPA2: A predefined key is used for both parties.
2. Extensible Authentication Protocol (EAP): Uses a secure authentication method to negotiate a shared secret key between two parties.
3. TLS: Uses a combination of a public key and a symmetric encryption algorithm to establish a shared secret key. The process typically involves Diffie-Hellman Key Exchange, RSA Key Exchange, or Elliptic Curve Key Exchange followed by a hash function like SHA-1 or SHA-256 for generating the session key.
