....3. THE DESIGN OF PUBLIC KEYKERBEROS AUTHENTICATION FOR MOBILE ENVIRONMENTS Many current security architectures employ public key cryptography to implement confidentiality, integrity, and availability features. There are several proposals to add public key cryptography to the stages of Kerberos [1, 13 14]. The proposal to add public key cryptography to the initial user authentication in Kerberos is documented in an IETF draft and called PKINIT [1] The PKINIT transaction is illustrated in Figure 3. Adapting PKINIT to a mobile computing platform would provide a mature authentication mechanism for ....

.... to Kerberos Internet drafts exist for three alternatives: 1) Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) 7] 2) Public Key Cryptography for CrossRealm Authentication in Kerberos (PKCROSS) 8] and (3) Public Key Utilizing Tickets for Application Servers (PKTAPP) [9]. PKINIT is the core specification. Both PKCROSS and PKTAPP use variations of PKINIT message types and data structures to apply public key cryptography to different Kerberos authentication steps. PKINIT. The PKINIT Internet draft specifies that considerable message content must be added to the ....

....AS TGS combination. Recently, optional Kerberos extensions have been proposed to support the use of public key cryptography for certain tasks, including initial user login (PKINIT) 20] interdomain authentication and key distribution (PKCROSS) 19] and peer to peer authentication (PKTAPP) [17]. We note that the last two have not progressed past Internet Drafts (expired) and no implementations are available. Although these extensions make Kerberos more attractive (since public key cryptography lends itself to greater security and scalability) Kerberos still remains a fairly heavyweight ....
