Abstract

The development of telecommunications and computer science has created a favorable climate regarding the increased development of electronic communication and has also led to an increase in the number of electronic documents that are being generated, stored or transmitted via computer networks. These documents are valuable but prone to manipulation by unauthorized persons that consequently leads to a need for enforced protection of the information contained in those documents from unauthorized third parties.
Digital signatures provide required validation and verification of electronic documents and represent a series of units and zeros obtained from a particular digital signature algorithm. The article emphasizes the practical application of digital signatures in the electronic system for public procurement by introducing the manner of the electronic signing of documents depending on the application software used by users in the Republic of N. Macedonia.
