We introduce <i>split-level I/O scheduling</i>, a new framework that splits I/O scheduling logic across handlers at three layers of the storage stack: block, system call, and page cache. We demonstrate that traditional block-level I/O schedulers are unable to meet throughput, latency, and isolation goals. By utilizing the split-level framework, we build a(More)
Signcryption is a cryptographic primitive that fulfill the functionalities of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional sign-then-encrypt or encrypt-then-sign approach. In this paper, we address the question whether it is feasible to construct a PKI based signcryption(More)
Inspite of the rapid advancements in storage technology, the fundamental architecture of storage in operating system remains fixed. Applications invoke the kernel to store and retrieve data and kernel invokes the file system. Recent work suggests a new class of memory called storage class memory(SCM) which blurs out the distinction between fast, expensive(More)
