Abstract
This contibThis contribution proposes a framework for authenticated key distribution in
ATM networks in endpoint-to-endpoint, switch-to-switch, and endpoint-to-switch
settings. The proposal is for a two-tiered hierarchy with initial pairwise key
distribution based on public key cryptography and subsequent session key
distribution based on conventional cryptography. All protocols are derived from
exsisting international standards and offer flexiblity with respect to the
number of message flows and the use of encryption.
