name: IBE
full_form: Identity-Based Encryption
context: In MCPTT for a protected private call, a symmetric key is created and passed to the target device using IBE during call setup. The symmetric key is subsequently used for SRTP protection of the media throughout the session. The intent is to reuse this private call structure as part of the common architecture for MCX protected private communications. MCVideo should follow the common architecture for protecting private video communications and therefore it is proposed that MCVideo protected private communications align with MCPTT protected private communications by using a symmetric key created and passed to the target device using IBE during video private communications setup.
description: Identity-Based Encryption (IBE) is a cryptographic technique used to secure communication, particularly in MCPTT and MCVideo protected private communications. It facilitates the generation and exchange of symmetric keys between devices during call setup.
explanation: The text describes IBE as a cryptographic technique used for secure communication within specific 3GPP standards (MCPTT and MCVideo). Its function is to enable secure key exchange, classifying it as a technology.
