The two-volume set LNCS 9614 and 9615 constitutes the refereed proceedings of the 19th IACR International Conference on the Practice and Theory in Public-Key Cryptography, PKC 2016, held in Taipei, Taiwan, in March 2016.
The 34 revised papers presented were carefully reviewed and selected from 143 submissions. They are organized in topical sections named: CCA security, functional encryption, identity-based encryption, signatures, cryptanalysis, leakage-resilient and circularly secure encryption, protocols, and primitives.

As a nation makes the transition from communism to democracy or another form of authoritarianism, its regime must construct not only new political institutions, but also a new political ideology that can guide policy and provide a sense of mission. The new ideology is crucial for legitimacy at home and abroad, as well as the regime's long-term viability. In The Return of Ideology, Cheng Chen compares post-communist regimes, with a focus on Russia under Putin and post-Deng China, investigating the factors that affect the success of an ideology-building project and identifies the...

The fall of communism in the Soviet Union led many to hope and expect that liberal democracy would immediately take root across postcommunist states, marking what Francis Fukuyama famously referred to as the "end of history." Since then, however, a very different picture has emerged, most notably in the form of nationalist sentiments that have steered many postcommunist countries in an illiberal direction, even in regimes committed to market reforms and formally democratic institutions.

Cheng Chen examines this phenomenon in comparative perspective, showing that the different...

This thesis explores the physics of non-equilibrium quantum dynamics in homogeneous two-dimensional (2D) quantum gases. Ultracold quantum gases driven out of equilibrium have been prominent platforms for studying quantum many-body physics. However, probing non-equilibrium dynamics in conventionally trapped, inhomogeneous atomic quantum gases has been a challenging task because coexisting mass transport and spreading of quantum correlations often complicate experimental analyses. In this work, the author solves this technical hurdle by producing ultracold cesium atoms in a quasi-2D optical...
