# Voice communication security workshop

Hi,

i made a talk about voice communication security technologies at University of Trento following an interesting information exchange with [Crypto Lab](http://www.science.unitn.it/~sala/lab/index.html) managed Professor [Massimiliano Sala](http://www.science.unitn.it/~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.

View more [presentations](http://www.slideshare.net/) from [Fabio Pietrosanti](http://www.slideshare.net/fpietrosanti).

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.
