Cryptographic mechanisms
WebMar 11, 2024 · Block ciphers such as Data Encryption Standard (DES), TripleDES, and Advanced Encryption Standard (AES) cryptographically transform an input block of n bytes into an output block of encrypted bytes. If you want to encrypt or decrypt a sequence of bytes, you have to do it block by block. 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.
