Analysis of broadcast schemes that implement identity-based encryption algorithms

In the context of an unsecure transmission channel, identity-based cryptography makes it possible to implement broadcast data transfer for a large number of recipients much more effective than classical public-key cryptography. A comparative analysis of such schemes is carried out and recommendations on selecting a particular scheme based on the system requirements (whether it is a public or private system, how often and how the group of recipients and security level changes, etc.) are provided.
