DIGITAL SIGNATURE DESIGN AND APPLICATIONWITH PUBLIC KEY CRYPTOGRAPY(M.Sc. Thesis)Meryem KIRIMLIGAZİ UNIVERSITYINSTITUTE OF SCIENCE AND TECHNOLOGYJanuary 2007ABSTRACTIn this thesis, after being given a general information aboutcryptography methods and digital signatures, Village Clinic ControlSystem (VCCS) which is projected with using RSA encryption andsignature algorithm is taken up. Using this , Village Clinic ControlSystem, datas, belonging to all village clinics in the cities and counties,is provided to gather with a central server through a web interface. Atthe same time, these datas, which have high risk, should be protectedagainst probable attack from inside or outside of clinic. For this reason,all datas are sent with digital signature using developed java securitysoftware. Therefore, reaching the sources is undercontroled withdetermining personal digital identity and also these data contentswhich are transfered on the electronic environment are protected.Science Code : 702.3.006Key Words : Public Key, Private Key, Digital Signature, EncryptionDecryptionPage Number : 78Adviser : Asisst.
