AI Technical Summary

Technical Problem

Existing decentralized cryptocurrency systems face inefficiencies and scalability issues due to the need for trust between parties, high computational overhead, and resource consumption in consensus mechanisms, limiting their use for small or low-computational power devices like IoT devices.

Method used

A method using a UICC (SIM card) with a secure element to generate public and private key pairs, enabling secure transactions on a distributed ledger without relying on public blockchains, and utilizing a proxy server for centralized management to reduce computational load and build trust between entities.

Benefits of technology

This approach reduces computational overhead, enhances scalability, and enables secure, efficient transactions for IoT devices by leveraging trusted UICC-generated identifiers and centralized management, facilitating trust between entities without the need for extensive computational resources.

Abstract

A method for recording transactions on a distributed ledger, the method comprising: generating a private and public key pair using an applet on a UICC in a device; storing the generated private and public key pair in the UICC; deriving an identifier from a public key of the generated private and public key pair; and adding one or more transactions to a block of the distributed ledger, wherein the one or more transactions are identified using the derived identifier.
