The article is devoted to the implementation of its own approach to the verification of digital certificates using Blockchain direction to protect the Windows operating system. The methods of increasing the level of protection of the Windows operating system that can be used for certificate verification are analyzed and proposed.
A new direction of Blockchain is proposed for the implementation of verification, due to the introduction of various verifications, which allows for a qualitative assessment of the authenticity of digital certificates. Today, Blockchain technology is perfect for checking, exchanging and protecting digital certificates. The list of the issuer and the recipient, the signature of the document in an open database, which is the same as in the computers on the open network, is stored. Compared to conventional digital certificates, certificates generated using blockchain technology has the following advantages: no need for intermediaries; certificate verification will be performed by an open source program; you can be sure exactly who and to whom the certificate was issued; the confidentiality of the document being signed is preserved. As you can see, this technology is able to create a powerful, secure, trusted and reliable structure that does not require any intermediaries or regular inspections. Due to the variety of inspection methods, the resources that this area provides, you can achieve maximum validation of both individual certificates and entire chain.Blockchain network is a guarantee of reliability and validity of data, but if someone still wants to confirm the validity of the certificate, you must obtain the public key of the person who signed it. Due to the lack of constant confirmation of certificates, this approach simplifies the administration of the network.
The practical value of the study is as follows: the authors have proposed their own approach, which allows you to check single certificates and certificate chains thanks to the Blockchain direction, which allows you to establish a secure connection and reliable data transmission. Because the proposed approach allows multiple certificate checks, it can be further integrated into the Windows operating system and can be used to protect a personal computer or used in corporate structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
