Abstract
A novel, trusted, and secure durable medium electronic service is proposed in the paper. The proposed idea joins cryptographic methods (such as signing with an electronic seal and data encryption) with blockchain techniques. The e-service and blockchain databases were implemented on the TTP side, which made the presented concept trusted and secure. The proposed electronic service was oriented towards practical implementations, and it has commonly been developed together with a company from the cybersecurity field (which is considered a TTP in the proposed approach). The concept has been designed to meet the requirements of Polish law (i.e., the conditions and regulations related to the implementation of the durable medium in Poland); nevertheless, it can easily be adapted for other regions. The functionality of the presented e-service is illustrated by the example case study.
Highlights
The production and processing of documents is a hallmark of the modern world
The decryption process applies the symmetric key, and the encrypted document is taken from the given blockchain node
The core of the presented approach is the blockchain database, where critical data are stored, signed, and encrypted. Such a compilation of modern blockchain technology and cryptographic methods prevents tampering with the blockchain database, which is the main concern of customers and one of the biggest disadvantages of currently used solutions
Summary
The production and processing of documents is a hallmark of the modern world. From an ecological point of view, positive changes have be seen in the decreasing utilization of paper documents (in favor of electronic versions). This solution was selected for further development of the durable medium e-service presented in the paper. The work presents a broad overview of the possible applications and challenges of blockchain technology This is a typical survey paper; no new ideas are shown nor new techniques proposed. Paper [19] describes the so-called “S3DOC Witness” technique, which offers electronic signing of documents This method applies the TTP idea without transferring personal data. The proposed approach utilizes cryptographic methods combined with blockchain technology Both the e-service and blockchain database are implemented on the TTP side, which makes it trusted and secure. The last section is devoted to the final remarks and conclusions
