Cryptography mechanism
WebWe propose a cryptographic obfuscation scheme for smart contracts based on existing blockchain mechanisms, standard cryptographic assumptions, and witness encryption. In the proposed scheme, an obfuscated smart contract does not reveal its algorithm and hardcoded secrets and preserves encrypted states. WebApr 27, 2024 · Cryptography is a technique that involves concealing the data to be transmitted so that only the receiver can look at it. This is often done by encrypting the data to be sent from the sender’s end and decryption the data at the receiver’s end.
