A general encryption scheme based on MDS code

In this paper, we propose to combine cryptographically strong random key stream generators (including those used in stream ciphers) with simple block encoders to achieve both high cryptographic strength and low computation complexity of encryption and decryption. In particular, we show proper error-correcting codes can be used as block encoders. In general, encoding and decoding of a proper block error (or more accurately erasure) correcting code is much faster than encryption and decryption of block ciphers.
