Voice communication security workshop


i made a talk about voice communication security technologies at University of Trento following an interesting information exchange with Crypto Lab managed Professor Massimiliano Sala .

I suggest interested people to read it, especially the second part, as there is an innovative categorization of the various voice encryption technologies that get used in several sectors.

I tried to explain and get out from this widely fragmented technological sector by providing a wide overview on technologies that usually are absolutely unrelated one-each-other but practically they all apply to voice encryption following that categorization:

  • Mobile TLC Industry voice encryption standards
  • Government and Military voice encryption standards
  • Public safety voice encryption standards
  • IETF voice encryption standards
  • Misc proprietary voice encryption technologies

It’s a huge slideware, 122 slides, i suggest to go reading the 2nd part skipping interception technologies overview already covered by my presentation of 2009.

Voice communication security

Especially i like the concept of Chocolate grade encryption that want to provide some innovation on the Snake Oil Encryption concept.

But i need to get more in depth about the Chocolate grade encryption context, will probably do before end-of-year by providing an applied course on understanding and evaluating practically the real security context of various voice encryption technologies.
