Arista certification method used for optical module, Arista certification device used for optical module, and optical module

Abstract

The invention discloses an Arista certification method used for an optical module, an Arista certification device used for the optical module, and the optical module. The Arista certification method comprises steps that the optical module is disposed in target equipment by the golden finger thereof, and after electrification, the processor of the optical module is used to load optical module Arista certification software stored in a Flash memory to an RAM memory for operation, and the processor of the optical module, the Flash memory, and the RAM memory are disposed in the embedded chip of the optical module; after cipher key data transmitted by the target equipment is received by the processor of the optical module via the golden finger, the cipher key data is stored in the Flash memory; the processor of the optical module is used to calculate a deciphering result according to the cipher key data; the processor of the optical module is used to transmit the deciphering result to the target equipment by the golden finger, and the Arista certification of the target equipment is accepted. By adopting the Arista certification method, the optical module can be successfully certified without requiring an external memory, and therefore applicability is good.

Description

technical field [0001] The invention relates to the technical field of optical modules, in particular to an Arista authentication method for optical modules, an authentication device and an optical module. Background technique [0002] The Arista (Arista) algorithm is an authentication algorithm, which is usually applied in the encryption authentication of the optical network. In practical applications, in order to establish an encrypted and protected optical network, the Arista algorithm software (in this paper, the Arista algorithm software is defined as Arista authentication software) will be set in the computers and optical modules participating in the construction of the optical network, so as to The computer and the optical module are authorized by Arista, and then the encrypted protection of the optical network is realized through the Arista authentication between the two. [0003] During the Arista certification process, the computer and the optical module run the A...
