The paper explores new approaches to developing methods for storing big data using various cryptographic solutions, such as the Shamir secret sharing method, the Diffie-Hellman key distribution protocol, etc. Note that various researchers have proposed various methods for storing data in the cloud. In this paper, we explore methods and protocols for secure outsourcing for storing big data using secret sharing technology and analyze their resistance to active and passive attacks. Such problems are especially relevant in the context of the rapid development of the Internet of Things (IoT). Chips, smart cards, and other physically small devices tend to have significant memory limitations, so there is a need to use cloud storage as an auxiliary tool for secure data storage.
Keywords: cryptography, information security, cloud storage, client-server interaction, internet of things.
