In this paper, we studied the research areas of Chinese natural science basic research from a point view of complex network. Two research areas are considered to be connected if they appear in one fund proposal. The explicit network of such connections using data from 1999 to 2004 is constructed. The analysis of the real data shows that the degree distribution of the research areas network (RAN...

POSTER ABSTRACT—Quantum Key Distribution (QKD) is an innovative technology which exploits the laws of quantum mechanics to generate and distribute unconditionally secure shared key for use in cryptographic applications. While QKD offers the promise of unconditionally secure key distribution, real world systems are built from non-ideal components which necessitates the need to understand the imp...

This paper introduces a completely new approach to encryption based on group theoretic quantum framework. Quantum cryptography has essentially focused only on key distribution and proceeded with classical encryption algorithm with the generated key. Here, we present a first step towards a quantum encryption scheme based on the solution for the hidden subgroup problem. The shared secret key K fr...

Quantum Key Distribution (QKD) is an innovative technology which exploits the laws of quantum mechanics to generate and distribute unconditionally secure shared keying material for use in cryptographic applications. However, QKD is a nascent technology where real-world systems are constructed from non-ideal components, which can significantly impact system security and performance. In this pape...

This memo documents a method for a Kerberos Key Distribution Center (KDC) to respond to client requests for Kerberos tickets when the client does not have detailed configuration information on the realms of users or services. The KDC will handle requests for principals in other realms by returning either a referral error or a cross-realm Ticket-Granting Ticket (TGT) to another realm on the refe...

The macroeconomic effects of the COVID-19 pandemic were most severe for emerging market economies, representing middle world income distribution. This paper provides a quantitative economic theory why markets fared worse, on average, relative to advanced economies and low-income countries. To do so we adapt workhorse incomplete-markets macro model include epidemiological dynamics alongside key ...
