EHETL : Elliptic curve-based Homomorphic Encrypted Transaction Ledger

Introduction
EHETL is a Layer 2 blockchain technology that utilizes the additive homomorphic operations of the Elliptic Curve Homomorphic Cryptosystem to encrypt transaction data on the distributed ledger and enable processing in its encrypted state.

• Properties of EHETL
• Small encrypted data size using Partial Homomorphic Encryption.
• Fast encryption and computation processing speed.
• Establishing a multi-organization participation environment using institutional keys.

EHETL is designed to block unauthorized access to data through its encryption mechanism, while the properties of homomorphic encryption enable computations to be performed without decryption, thereby maintaining data confidentiality. Based on EHETL, the Crypto Blockchain has been developed, and a dedicated protocol has also been researched and developed for efficient utilization.
