CGKA-FA security Sample Clauses

CGKA-FA security. In this section, we describe the security of CGKA-FA. We consider the case that Add, Remove, and Update algorithms contain ratcheting signatures. The only difference in security between CGKA and CGKA-FA is the presence or absence of a digital signature. The difference in security between CGKA and CGKA-FA is the presence or absence of ratchet signatures. Since the GM takes over the PKI functionality in CGKA-FA, it is necessary to clarify some conditions for the GM. First, since the GM creates initial keys for group members, the GM is assumed to be uncompromised until the first update is performed by each group member. Then, after each group member performs an update, the GM can perform an update at any time. This means that we do not assume an adversary who will not even allow an update to be performed. These conditions are implicitly assumed for all group members in CGKA. The CGKA-FA security game can be played in much the same way as the CGKA security oracle. However, since CGKA-FA uses ratcheting signatures, we define here the oracle vrfy that verifies the signatures. vrfy does not have to be an Oracle but is defined here as a new security oracle because it simplifies the game by defining it according to a security game such as [3].
