Heterogeneous devices have been adopted widely in mobile storage systems because a combination of such devices can supply a synergistically useful storage solution by taking advantage of each device. In heterogeneous storage systems there have been several researches for enhancing I/O performance by devising proper buffer cache management algorithms. This paper presents a novel device-aware buf...

Today’s storage interfaces hide device-specific details, simplifying system development and device interoperability. However, they prevent database systems from exploiting devices’ unique performance characteristics. Abstract and device-independent annotations to existing storage interfaces can cleanly expose key device characteristics that improve performance and simplify manual tuning. By aut...

Consumer electronics and embedded devices often allow the installation of applications and firmware upgrades from user-provided mass-storage devices. To protect the integrity of these devices and the associated electronic markets, the software packages are protected by cryptographic signatures. The software installation code assumes that files on attached mass-storage devices cannot change whil...

Caching data files directly on mobile user devices combined with device-to-device (D2D) communications has recently been suggested to improve the capacity of wireless networks. We investigate the performance of regenerating codes in terms of the total energy consumption of a cellular network. We show that regenerating codes can offer large performance gains. It turns out that using redundancy a...

— With the advent of flash memory based new storage device (SSD), there is considerable interest within the computer industry in using flash memory based storage devices for many different types of application. The dynamic index structure of large text collections has been a primary issue in the Information Retrieval Applications among them. Previous studies have proven the three approaches to ...

BACKGROUND Self-poisoning with pesticides is the cause of an estimated 300,000 deaths annually in rural Asia. The great majority of these deaths are from impulsive acts of self-harm using pesticides that are readily available in the home. The secure storage of pesticides under lock has been emphasized as a possible answer to the problem. This aspect, however, has been poorly researched. In this...

A write blocker allows read-only access to digital data on a secondary storage device by placing a hardware or software filter between the host computer and the storage device. The filter monitors I/O commands sent from the application on the host computer, only allowing commands to the device that make no changes to its data. This paper examines the I/O commands used to access secondary storag...

A PUF is a chip-unique challenge-response mechanism exploiting manufacturing process variation inside integrated circuits (ICs). It has many useful applications such as device authentication and secure, memory-less key storage. A mobile device can be authenticated using a PUF challenge-response pair. Moreover, a cryptographic key can be securely embedded in a mobile device using a PUF without a...
