With the expansion of RFID technology application in diverse fields, the security problems attract more and more attention. In the RFID Security authentication protocols used public-key cryptography, the authentication protocol based on the ECDLP (Elliptic Curve Discrete Logarithm Problem) can solve the clone and reply attacks very well, but there are more(More)
The exponential growth of next generation sequencing (NGS) data has posed big challenges to data storage, management and archive. Data compression is one of the effective solutions, where reference-based compression strategies can typically achieve superior compression ratios compared to the ones not relying on any reference. This paper presents a lossless(More)
SUMMARY Exhaustive mapping of next-generation sequencing data to a set of relevant reference sequences becomes an important task in pathogen discovery and metagenomic classification. However, the runtime and memory usage increase as the number of reference sequences and the repeat content among these sequences increase. In many applications, read mapping(More)
Many kinds of protocols have been designed to resolve the security and privacy problems of RFID systems. In this paper, we illustrate a new RFID authentication protocol based on Trivium, inspired from the Challenge-Response based RFID authentication protocol for distributed database environment. The proposed protocol can prevent many attacks including(More)
Domain Name System (DNS) is one of the most crucial components of the Internet. However, due to the vulnerability of DNS, its security has been continuously challenged in recent years. In order to thoroughly understand the root cause of the security risks in the DNS, researches in DNS security are surveyed, and vulnerabilities in DNS and corresponding(More)
We report a hybrid up-conversion device integrating a In0.2Ga0.8As/GaAs MQWs photodetector with an organic light emitting diode (OLED), that converts input 980 nm infrared light to output 520 nm green light. Devices with different interface layer, used as the hole injection layer (HIL) in OLEDs were fabricated and tested. It was found that the device with(More)

Effects of doping molybdenum oxide (MoO3) in copper phthalocyanine (CuPc) as hole injection layer in OLEDs are studied. A green OLED with structure of ITO/MoO3-doped(More)
The rapid development of Internet attack has posed severe threats to information security. Therefore, it's of great interest to both the Internet security companies and researchers to develop novel methods which are capable of protecting users against new threats. However, the sources of these network attack varies. Existing malware detectors and intrusion(More)
An organic/inorganic hybrid up-conversion device was demonstrated in this work, which can convert near-infrared light (NIR) to visible green at high conversion efficiency. The upconverter was fabricated by integrating an In(0.12)Ga(0.88)As/GaAs multiquantum wells (MQWs) photodetector (PD) with an organic light emitting diode (OLED). The up-conversion(More)
