In the latter case, the power was momentarily dropped in order to cause the release of the chip's security lock. Military-grade integrated circuits have better temperature tolerances, but the wider range was intended to accommodate harsh weather conditions and not security attacks. We have so far explored several possibilities which, however off the beaten path they may seem, still revolve around computing and electricity. The key here is the massive parallelization of the combinatorial work that takes place when all DNA sequences are mixed up and shaken. The entire technique is useless, for the creators of the message would encrypt the data much faster with existing software or DES chips.
Molecular cryptanalysis is still an emerging field.
The techniques are still prone to errors, but here is yet another example in which security can be broken by taking a totally different approach from those considered by the designers of a mechanism. The strength of DES remains in only being attackable through brute force and, with classic computing, this takes a lot of time. Traffic Analysis Let us go back to the digital world now. In many of the examples above, we wrote about breaking an encrypted message or a system. The best spy is one that the counter-intelligence service does not know of.
