A Hardware One-Time Pad Prototype Generator for Localising Cloud Security (2017)

A Hardware One-Time Pad Prototype Generator for Localising Cloud Security (2017)

Tobin, Paul; Tobin, lee; McKeever, Mick; Blackledge, Jonathan

Abstract:

In this paper, we examine a system for encrypting data before storing in the Cloud. Adopting this system gives excellent security to stored data and complete control for accessing data by the client at different locations. The motivation for developing this personal encryption came about because of poor Cloud security and doubts over the safety of public encryption algorithms which might contain backdoors. However, side-channel attacks and other unwanted third-party interventions in Cloud security, probably contribute more to the poor security record history. These factors led to the development of a prototype for personalising security locally which defeats cryptanalysis. The key distribution problem associated with random binary sequences called one-time-pads, does not exist for one-to-Cloud applications, unlike bidirectional communications where it was a big issue. The random binary sequences were generated from chaotic analogue oscillators with initial conditions from a...

Comparative Field Performance Study of Flat Plate and Heat Pipe Evacuated Tube Collectors (ETCs) for Domestic Water Heating Systems in a Temperate Climate (2011)

Ayompe, Lacour; Duffy, Aidan; McCormack, Sarah; McKeever, Mick; Conlon, Michael

Abstract:

This paper presents a year round energy performance monitoring results of two solar water heaters with 4 m2 flat plate and 3 m2 heat pipe evacuated tube collectors (ETCs) operating under the same weather conditions in Dublin, Ireland. The energy performance of the two systems was compared on daily, monthly and yearly basis. Results obtained showed that for an annual total in-plane solar insolation of 1,087 kWh/m2, a total of 1,984 kWh and 2,056 kWh of heat energy were collected by the 4 m2 FPC and 3 m2 ETC systems respectively. Over the year, a unit area of the FPC and ETC each generated 496 kWh/m2 and 681 kWh/m2 of heat respectively. For 3149.7 kWh and 3053.6 kWh of auxiliary energy supplied to the FPC and ETC systems their annual solar fractions (SFs) were 38.6% and 40.2% respectively. The annual average collector...

Validating the Performance of a Prototype Phase Change Material for a Thermal Energy Storage Tank, Connected to a Micro-CHP (2015)

Validating the Performance of a Prototype Phase Change Material for a Thermal Energy Storage Tank, Connected to a Micro-CHP (2015)

McKeever, Mick

Abstract:

This paper describes the performance testing of a 2000-litre phase change material used in a Thermal Energy Storage (PCM-TES) demonstrator unit invented in DIT’s Dublin Energy Lab and installed in an office building in Cork in 2014. The PCM-TES is connected to a Micro-CHP unit and stores waste heat from the CHP at evening peak tariff periods when the building heating loads are lowest. The CHP is also connected to a 2000-litre water tank allowing direct comparison of the energy storage capacities and performances of both storage systems. Charging results presented show that the PCM-TES holds 6.5 times more heat for the same plant room footprint, allowing the CHP to run continuously during peak periods and producing a better overall electrical/ thermal efficiency. Discharging results show how the PCM-TES stored energy can be used to pre-heat the building heating system early in the morning, shifting CHP thermal demand to align better with the day rate electrical tariff period...
