National Security Agency encryption devices
The STU-II (Standard Telephone Unit II) is a secure telephone developed by the U.S. National Security Agency. It permitted up to six users to have secure communications, on a time-shared (e.g.: rotating) basis. It was made by ITT Defense Communications, Nutley, New Jersey. An OEM partner was Northern Telecom. According to information on display in 2005 at the NSA's National Cryptologic Museum, the STU-II was in use from the 1980s to the present. It uses the linear predictive coding algorithm LPC-10 at 2.4 kilobits/second to digitize voice, and the "Key Distribution Center" (KDC) for key management. The display also stated that the STU-II B is the standard narrow band secure telephone. STU-II replaced the STU-I, KY-3 and the Navajo I. The last was a secure telephone in a briefcase, of which 110 were built in the 1980s for use by senior government officials when traveling. The Navaho I also used LPC-10. Some 10 000 STU-II units were produced. (Wikipedia).

Michele Caselle - Using the Ising model to explore the confining regime of Lattice Gauge Theories
Understanding the physical mechanisms behind confinement is one of the most important open problems in Lattice Gauge Theories (LGTs). In this talk we discuss two exemplary applications of the Ising model to this problem. In the first example we study the quark-antiquark correlator in the L
