Abstract (2. Language): 
Authorization systems makes it possible that a user could only act in accordance with the permissions defined by the functional group it belongs. The authorization control mechanism employed in workflow became insufficient for the external enterprise processes as inter-agency correspondences. In this study, the sustainability of authorization in enterprise workflow, documents in circulation and long-term archives has been analyzed and demonstrated with Petri net models. Furthermore, a case study on digital signatures for the deficiencies of the enterprise authorization is presented. An authorized signature model is also proposed where authorization is employed in digital signature for the sustainability of authorization. The proposed solution is implemented using pairing based cryptography and analyses are provided.

Abstract (Original Language): 
Yetki denetim sistemleri, kurumdaki kullanıcının, ait olduğu fonksiyonel gruba tanımlanan izinler doğrultusunda işlem yapabilmesine olanak tanımaktadır. Kurum içi iş akışında uygulanan bu denetim, yetki kontrolünde kurumlar arası yazışmalar gibi kurum yapısı dışına çıkan süreçlerde yetersiz kalmaktadır. Bu çalışmada, yetki denetiminin, kurumsal iş akışında, dolaşımda ve arşivlenen belgeler kapsamında süreklilik analizi, petri ağları yöntemi ile ortaya konulmuştur. Kurumsal yetki denetimindeki eksiklikler için sayısal imza üzerinde bir vaka çalışması yapılmış ve yetki denetiminin sürdürülebilirliği için imzanın yetki denetimi işleviyle donatıldığı bir çözüm modeli önerilmiştir. Bu çözüm, eşleme tabanlı kriptografi ile gerçeklenmiş ve yapılan analizler çalışmaya dâhil edilmiştir.
