The present application describes a method, system, and non-transitory computer-readable medium for end-to-end encryption during a secure communication session. According to the present disclosure, a first device initializes a secure communication session with at least one second device. Initializing the secure communication session includes transmitting an invitation to a secure communication session to the at least one second device. The first device subsequently receives the token from the at least one second device and validates the token. When the token is invalid, the first devices terminates the secure communication session. However, when the token is valid, the first device performs a three-way handshake with the at least one second device to negotiate a first encryption key and a second encryption key. The first encryption key is used to encrypt communication data transmitted by the first device and the second encryption key is used to decrypt communication data received from the at least one second device.
