ACISP2001,theSixthAustralasianConferenceonInformationSecurityandP- vacy,washeldinSydney,Australia. TheconferencewassponsoredbyInfor- tionandNetworkedSystemSecurityResearch(INSSR),MacquarieUniversity, theAustralianComputerSociety,andtheUniversityofWesternSydney. Iam gratefultoalltheseorganizationsfortheirsupportoftheconference. Theaimofthisconferencewastodrawtogetherresearchers,designers,and usersofinformationsecuritysystemsandtechnologies. Theconferenceprogram addressedarangeofaspectsfromsystemandnetworksecuritytosecureInternet applicationstocryptographyandcryptanalysis. Thisyeartheprogramcomm- teeinvitedtwointernationalkeynotespeakersDr. YacovYacobifromMicrosoft Research (USA) and Dr. Cli?ord Neumann from the University of Southern California(USA). Dr. Yacobi stalkaddressedtheissuesoftrust,privacy,and anti-piracyinelectroniccommerce. Dr. Neumann saddresswasconcernedwith authorizationpolicyissuesandtheirenforcementinapplications. Theconferencereceived91papersfromAmerica,Asia,Australia,and- rope. The program committee accepted 38 papers and these were presented insome9sessionscoveringsystemsecurity,networksecurity,trustandaccess control,Authentication,cryptography,cryptanalysis,DigitalSignatures,Elliptic CurveBasedTechniques,andSecretSharingandThresholdSchemes. Thisyear theacceptedpaperscamefromarangeofcountries,including7fromAustralia, 8fromKorea,7fromJapan,3fromUK,3fromGermany,3fromUSA,2from Singapore,2fromCanadaand1fromBelgium,Estonia,andTaiwan.
