First Formal DDS Security
As noted in today’s article on some of the characteristics of the DDS data transport standard, it’s missing a rather important component: formalized security. Proprietary schemes have been layered on top of it, but the OMG has a beta standard that they’re now finalizing (a process that could take up to a year).
But that doesn’t stop early adoption. RTI has announced an implementation of the new OMG security standard for DDS – something likely made easier since, by their claim, they contributed much of the content of the standard.
There are a couple of particular challenges with respect to security on DDS. First, due to its decentralized nature, there are no brokers or single-points-of-security (which would be single points of failure). This means that each device or node has to handle its own security.
