a few ideas related to the context for crypto today.

there is certain irony in crypto that can be subverted and used to attack or surveil via stealth. reminds of the basic situation with most home electronics, blackboxed. such as IPcams that remain on 24/7/365 and have microphones accessible over the network, compromises built-in. thus to seek security is to extend the hidden security state and its illegal home invasion. solution: five dollar on/off switch, activate security device only when away, and upon return turn it off again, limiting the designed for boundlessness of political technology.

this is the direct reference and extension of the NSA diagram above. cryptanalysis was included, Technical Surveillance Countermeasures (TSCM), though likely other domains are missing or perhaps in relational error.  improvements or corrections appreciated...

this is my estimation of the situation today, based on the above technosocial structure. it does not include many aspects and is limited by my lack of awareness and understanding, though makes an attempt at an integrated view of the larger dynamics involved...
