One of the main challenges of securing multicast communication is source authentication, or enabling receivers of multicast data to verify that the received data originated with the claimed source and was not modified en-route. The problem becomes more complex in common settings where other receivers of the data are untrusted, and where lost packets are not retransmitted.

A detailed description of TESLA is in our book.
