Distributed applications typically involve many components, each with unique security and privacy requirements. Such applications require fine-grained access control mechanisms that allow dynamic delegation and revocation of access rights. Embedding such domain-specific requirements in a functional language like Haskell puts all the expressiveness of the(More)
—We present a model for securing Map/Reduce computation in the cloud. The model uses a language based security approach to enforce information flow policies that vary dynamically due to a restricted revocable delegation of access rights between principals. The decentralized label model (DLM) is used to express these policies. We present a scenario that(More)
Mycetoma is a unique neglected tropical disease which is endemic in what is known as the "mycetoma belt". The disease has many devastating impacts on patients and communities in endemic area and is characterised by massive deformity, destruction and disability. Mycetoma is commonly seen in the foot and hand and less frequent in other parts of the body.(More)
This paper focuses on the different challenges to design a security typed web scripting language. It uses the type system approach on a simple imperative language that captures a subset of the security typed web language constructs to express the security properties that must be held in the language with respect to its formal semantics to prevent insecure(More)
BACKGROUND Uremic pruritus (UP) is a very distressing symptom and remains one of the most frustrating and potentially disabling symptoms in patients with end-stage renal disease (ESRD). Its etiopathogenesis remains unclear and complex. The aim of this study was to investigate the possible role of interleukin-2 (IL-2) in UP, and correlate its level with the(More)
