Encryption of error correction data using symbol-level ciphers

Abstract

Aspects and implementations include systems and techniques for encryption and decryption of error-corrected codewords for combined protection against corruption of data and adversarial attacks, including obtaining a block of data that has a first plurality of symbols, generating, based on the first plurality of symbols, a second plurality of symbols, wherein the second plurality of symbols includes one or more error correction symbols for the first plurality of symbols, encrypting the second plurality of symbols using a set of symbol-level ciphers (SLCs) to obtain an encrypted plurality of symbols, and using the encrypted plurality of symbols in a computer operation.
