Earlier today the DECT Forum issued a press release in response to news from last months Chaos Communications Congress (25C3) that the DECT encryption has been cracked. Their press release (PDF) is about what you’d expect. It merely asserts their willingness to work with researchers to develop new and better security provisions as part of the CAT-iQ standard that replaces DECT.
I would hope that they would not only develop a better standard, but also ensure that the encryption provisions are in fact implemented by manufacturers. To my mind the most frightful part of the DeDECTed groups work was finding that some DECT implementations were not encrypted at all. Further, that there was essentially no way for a non-technical user to know if the DECT system that they were buying was encrypted or not.
