# Fully Homomorphic Encryption

CycleNetwork employs Fully Homomorphic Encryption (FHE) to enable computations on encrypted data without needing decryption. This ensures that sensitive information remains secure throughout the cross-chain operations, offering complete privacy guarantees to users.

If you want to know more details about fully homomrphic encryption, you can read our [whitepaper](https://www.cyclenetwork.io/whitepaper.pdf) to learn deeply.
