However, at present, optical module manufacturers use fixed passwords for protection, that is, a large number of optical modules with the same firmware program use the same password. Some optical module manufacturers even use the same password for all optical modules they produce for convenience. One password, once the fixed password is leaked, the risk of a large number of products will be uncontrollable

Abstract

The present invention relates to an optical module encryption method and device. The encryption method includes the steps of: obtaining an identifier of an optical module, where the identifier is unique to the optical module; and performing encryption operation on the identifier to generate a password of the optical module; and saving the password inside the optical module. The invention providesa password for each optical module, and the password is unique and unique to the optical module, so that the use security of the optical module can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module encryption method and device. Background technique [0002] In order to ensure the safe use of the optical module, generally, the optical module manufacturer will set an access password for the optical module to protect the read / write area of ​​the optical module memory. However, at present, optical module manufacturers use fixed passwords for protection, that is, a large number of optical modules with the same firmware program use the same password. Some optical module manufacturers even use the same password for all optical modules they produce for convenience. A password, once the fixed password is leaked, the risk of a large number of products will be uncontrollable. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies in the prior art and provide an optical module encryption method and devic...
