In order to further improve the information security, data encryption effect and encryption strength of transmission network, a method of encrypting multiple overhead bytes is proposed. This paper analyzed the problems of high-speed information encryption, and proposed a channel encryption idea for SDH high-speed information by scrambling the key overhead bytes. The effectiveness of four kinds of SDH key-overhead-byte encryption, such as H1, H2 bytes, DCC bytes, J0, J1bytes and K1, K2 bytes, is analyzed.
