National Security Agency encryption devices
TSEC/KY-68 DSVT, commonly known as Digital Subscriber Voice Terminal, is a US military ruggedized, full- or half-duplex tactical telephone system with a built-in encryption/decryption module for secure traffic. It transmits voice and data at 16 or 32 kbit/s, converting voice to a digital signal. The KY-68 can operate via civilian and military switches in either encrypted or un-encrypted mode, or point-to-point (encrypted mode only). Although used primarily for secure communications, the KY-68 can also transmit to a Digital Non-secure Voice Terminal (DNVT). A local switch warns the KY-68 user with a tone signal when initiating communication with a non-secure terminal. The KY-68 is keyed using an Electronic Transfer Device, typically either a KYK-13 or AN/CYZ-10. An almost identical office version (KY-78) features the same electronics as the KY-68, but has an exterior casing composed of lighter materials. The KY-68 and KY-78 are approved for use with SECRET-classified information. (Wikipedia).

Sub-Weyl Subconvexity and Short p-Adic Exponential Sums - Djordje Milicevic
Djordje Milicevic April 17, 2012 One of the principal questions about L-functions is the size of their critical values. In this talk, we will present a new subconvexity bound for the central value of a Dirichlet L-function of a character to a prime power modulus, which breaks a long-standi
