WebFeb 1, 2024 · 3. Digital signatures. Besides the hash function, the digital signature is another inevitable cryptographic primitive in blockchains. The concept of the digital signature was put forward by Diffie and Hellman in 1976 when they opened the gate of public key cryptography ( Diffie and Hellman, 1976 ). WebIn this work, we implement regression models that can train on encrypted data with a relatively new cryptographic primitive, functional encryption for inner-product. In this …

Webcryptographic primitive that has only been described theoretically, and possibly optimize it further. A third option would be to formally analyse the security properties of the different schemes in the relevant models, provide complete security proofs and potentially modify the schemes to achieve better guarantees.
