In this paper, we propose the ticket-based delegation servicefor the multiple domain models.This scheme presentsan extension to the Kerberos [4] framework using publickey cryptosystem [13]. This proposed model, based onCORBAsec [1, 3, 12], supports the protection of thehigh-level resources and the preservation of the securitypolicies of the underlying resources that form the foundationof various domains, between the Kerberized do-mains[14] and the Non-Kerberized domains.Also weachieved the flexibility of key management and reliablesession key generation between the client and the providerusing the public key cryptosystem based ticket.
