Abstract
Systems, methods, and devices are provided for intermediate authentication of a message transmitted through a switched-path network, such as an optical transport network (OTN). In one method, a message transmitted through communication nodes of a switched-path network may be authenticated, at least partially, by authentication logic of one or more of the communication nodes. The one or more communication nodes may identify whether a prior communication node has tampered with or corrupted the message or may generate an authentication tag to enable an authentication authority to authenticate the message.
