Research of Methods of Secured Data Transmission in a Local Network
Abstract
Purpose. Study of methods and principles of ensuring secure data transmission in a local network and development of a software utility for establishing a secure communication channel.
Method. Based on the use of the AES cryptographic algorithm and the Diffie-Hellman key exchange protocol, as well as the application of byte sequence transformations during the generation of a shared secret key.
Findings. Consist in the analysis of the principles of functioning of end-to-end encryption (E2EE), consideration of cryptographic algorithms used within E2EE, and the study of Man-in-the-Middle (MITM) threats for such systems. Within the practical part, a utility was implemented that ensures secure data transmission in a local network.
Theoretical implications. Consists in deepening the understanding of cryptographic protection mechanisms when organizing secure data exchange in local networks.
Practical implications. Consists in creating an applied software implementation that can be used to form a secure communication channel in the conditions of publicly accessible or potentially vulnerable local networks.
The value. Consists in the possibility of using the proposed approach when designing or upgrading secure data exchange systems in network infrastructure of various scales.
