Dynamic content attacks on digital signatures
Purpose ‐ Aims to address some of the problems that arise when signing digital documents that contain dynamic content. Design/methodology/approach ‐ Briefly introduces the problem of signing digital documents with dynamic content and discusses possible locations for signature functionality in a computer system. Outlines existing solutions to the problems and introduces a novel solution. Finally, discusses issues and unresolved problems. Findings ‐ The suggested solution requires all document handling applications to possess application awareness of the digital signature program in order to function properly. Every application must implement a COM interface and register itself in the Registry, in a locale specific to the digital signature program to sign the digital document. Originality/value ‐ Provides a new solution to the problem of digitally signing a digital document.
