As technologies develop rapidly, digital signing is commonly used in eDocument security. However, unaddressed issues exist. An eCertificate system represents the problem situation, and therefore is being used as case study, in a project called eCert, to research for the solution. This paper addresses these issues, explores the gap between current tools and the desired system, through analysis of the existing services and eCertificate use cases, and the identified requirements, thereby presenting an approach which solves the above problems. Preliminary results indicate that the recommendation from this research meets the design requirements, and could form the foundation of future study of solving digital signing issues.
