Description: A session key is a unique key used to encrypt and secure a user session, ensuring that communication between the client and server remains private and protected from unauthorized access. This key is generated temporarily and used for the duration of a specific session, meaning it is not reused in future sessions. The session key is fundamental in security protocols like TLS (Transport Layer Security), where a secure connection is established between two parties. Its use allows for confidentiality, integrity, and authentication of transmitted data, ensuring that only authorized parties can access the exchanged information. Additionally, the session key is derived from a master key and is used in conjunction with encryption algorithms to protect data in transit. The temporary nature of these keys makes them less vulnerable to attacks, as their validity expires at the end of the session, thereby reducing the risk of compromising information security in the long term.
