Constructing identification schemes is one of the fundamental problems in cryptography, and is very useful in practice. An identitybased identification (IBI) scheme allows a prover to identify itself to a public verifier who knows only the claimed identity of the prover and some common information. In this paper, we propose a simple and efficient framework for constructing IBI schemes. Unlike s...

The dynamics of the uid elds in a large class of causal dissipative uid theories is studied. It is shown that the physical uid states in these theories must relax (on a time scale that is characteristic of the microscopic particle interactions) to ones that are essentially indistinguishable from the simple relativistic Navier-Stokes descriptions of these states. Thus, for example, in the relaxe...

The wave function of a system containing identical particles takes into account the relationship between a particle's intrinsic spin and its statistical property. Specifically, the exchange of two identical particles having odd-half-integer spin results in the wave function changing sign, whereas the exchange of two identical particles having integer spin is accompanied by no such sign change. ...

This paper describes a cognitively plausible computational theory of identifying perceptually indistinguishable objects (PIOs) based on a set of experiments which were designed to identify the knowledge and perceptual cues that people use for this purpose. Identifying a PIO in this context means connecting sensor data from some physical object either to a new mental level symbol or to the corre...

Communication anonymity is a key requirement for individuals under targeted surveillance. Practical anonymous communications also require indistinguishability — an adversary should be unable to distinguish between anonymised and nonanonymised traffic for a given user. We propose Blindspot, a design for high-latency anonymous communications that offers indistinguishability and unobservability un...

Quantum sealed-bid auction (QSA) is a special form of transaction with significant applications in the economic and financial fields. Using unique set locally indistinguishable orthogonal product (LIOP) states, we propose new QSA protocol this paper. In protocol, bid message encoded as quantum sequence LIOP different particles states are transmitted separately. Even though an attacker obtains p...
