Abstract: System wide information management (SWIM) provides the civil aviation information exchange and data
sharing function by using service-oriented architecture (SOA). Based on the analysis of SWIM architecture and the
sub-protocol EAP-MD5 of Diameter, the security vulnerable of authenticating process in standard Diameter/EAP-MD5 is
explored, the EAP-MD5 authentication protocol is improved, and the SWIM authentication service based on Diameter is
studied, then the SWIM authentication method based on improved Diameter/EAP-MD5 protocol is proposed. Experi-
ments on the security of SWIM authentication service based on Diameter are performed in SWIM simulation environ-
ment, results show that the improved Diameter/EAP-MD5 authentication method can enhance the security of SWIM au-
thentication and guarantee SWIM security service.
Key words: system wide information management (SWIM); Diameter protocol; extensible authentication protocol (EAP);
message-digest (MD) algorithm; identity authentication
