HEAX: An Architecture for Computing on Encrypted Data

Understand

With the rapid increase in cloud computing, concerns surrounding data privacy, security, and confidentiality also have been increased significantly.

• Not only cloud providers are susceptible to internal and external hacks, but also in some scenarios, data owners cannot outsource the computation due to privacy laws such as GDPR, HIPAA, or CCPA.
• Fully Homomorphic Encryption (FHE) is a groundbreaking invention in cryptography that, unlike traditional cryptosystems, enables computation on encrypted data without ever decrypting it.
• However, the most critical obstacle in deploying FHE at large-scale is the enormous computation overhead.
