Partially solved. Most Ham operators don't have to deal with adversaries. These radios need to stand up to jamming and eavesdropping. They also need to handle a (fairly complex) protocol automatically and in a dynamic configuration. Imagine a cell network with no tower, each phone is capable of becoming the leader. And multiple networks can exist in the same physical space. All traffic has to be encrypted to protect against eavesdropping, and frequency hopping and other techniques have to be incorporated to become jamming resistant.
