In DNS zone delegation, the NS resource records of the delegated domain appear in both the parent and child zones, which complicates the domain name resolution procedure especially for server selection. In this paper, we investigate the recursive resolution mechanism for the delegated domain and the necessary operations. As there are no specifications for such resolution, we provide some recomm...

In the past few years, outsourcing private data to untrusted servers has become an important challenge. This raises severe questions concerning the security and privacy of the data on the external storage. In this paper we consider a scenario where multiple clients want to share data on a server, while hiding all access patterns. We propose here a first solution to this problem based on Oblivio...

Authentication, authorization, and digital identity management are core features required by secure systems. In this, authorization is a key component for regulating the detailed access credentials with respect to service resources. Authorization, therefore, plays significant role in trust of autonomous devices services. Due heterogeneous nature cyber-physical systems Internet Things, several t...

This research has developed a simple to use, cost effective sensor system for the detection of lead ions in tap water. An under-potential deposited bismuth sub-layer on a thin gold film based electrochemical sensor was designed, manufactured, and evaluated. Differential pulse voltammetry (DPV) measurement technique was employed in this detection. Tap water from the Cleveland, OH, USA regional w...

Indolizine derivatives have been used in medicine and pharmacology due to their biological activity and therapeutical effects. Their capacity to form surface films and to be used as sensors in modern technologies makes them interesting to be studied. This work is devoted to the study of methyl-3-benzoyl indolizine carboxylates by cyclic voltammetry (CV) and differential pulse voltammetry (DPV)....

Consensus mechanism plays an important role in blockchain. At present, mainstream consensus mechanisms include proof of work (PoW), stake (PoS), and delegated (DPoS). PoW, as is widely used virtual currency, results significant energy consumption; PoS DPoS are proposed to reduce waste caused by but their disadvantage that they tend create Matthew Effect (ME): “the rich get richer.” In order bal...

This Article gives an overview of the legal framework governing delegated and implementing acts as established in Articles 290 291 TFEU, well practice institutions on preparation such process leading to their entry into force.

Semiquantum key distribution allows a quantum party to share a random key with a "classical" party who only can prepare and measure qubits in the computational basis or reorder some qubits when he has access to a quantum channel. In this work, we present a protocol where a secret key can be established between a quantum user and an almost classical user who only needs the quantum ability to acc...

We study the impact of delegated portfolio management on asset pricing in a large-scale experimental setting. As predicted by standard models, in early rounds of our experiments delegation has no impact on pricing; we replicate CAPM pricing as in earlier experiments without delegation. However, CAPM pricing fails in later rounds. We attribute this to the fund flows: investors tend to increase a...
