Abstract
An inline network traffic monitor is deployed inline between two endpoints of a computer network. A particular endpoint of the two endpoints works in conjunction with the inline network traffic monitor to decrypt encrypted network traffic transmitted between the two endpoints. A series of Change Cipher Spec (CCS) messages is exchanged between the inline network traffic monitor and the particular endpoint during a Transport Layer Security (TLS) handshake between the two endpoints. The series of CCS messages allows the particular endpoint and the inline network traffic monitor to detect each other on the computer network. After detecting each other's presence, the particular endpoint sends the inline network traffic monitor a session key that is used by the two endpoints to encrypt their network traffic. The inline network traffic monitor uses the session key to decrypt encrypted data of the network traffic transmitted between the two endpoints.
