Protecting Encryption Keys in Mobile Systems Against Memory Errors
Beyond its use to encrypt data, an encryption key can be used as a mean to control access to data on a mobile device by leveraging a cloud service. This implies that a key is present in a mobile device only when it is on demand and authorized by the cloud, the key is evicted when it is not in use. CleanOS is an example system that is based on this concept. For security reasons, keys are stored ...
متن کاملEntirely protecting operating systems against transient errors in space environment
In this article, we propose a mainly-software hardening technique to totally protect unmodified running operating systems on COTS hardware against transient errors in heavily radiation flooded environment like high altitude space. The technique is currently being implemented in a hypervisor and allows to control the upper layers of the software stack (operating system and applications). The res...
متن کاملPSF Anisotropy and Systematic Errors in Weak Lensing Surveys
Given the basic parameters of a cosmic shear weak lensing survey, how well can systematic errors due to anisotropy in the point spread function (PSF) be corrected? The largest source of error in this correction to date has been the interpolation of the PSF to the locations of the galaxies. To address this error, we separate the PSF patterns into components that recur in multiple exposures/point...
متن کاملSystematic errors in cosmic microwave background polarization measurements
We investigate the impact of instrumental systematic errors on the potential of cosmic microwave background polarization experiments targeting primordial B-modes. To do so, we introduce spin-weighted Müller matrix-valued fields describing the linear response of the imperfect optical system and receiver, and give a careful discussion of the behaviour of the induced systematic effects under rotat...
متن کاملWeak Value and Weak Measurements
The weak value of a variable O is a description of an effective interaction with that variable in the limit of weak coupling. For a pre-and post-selected system described at time t by the two-state vector Φ| |Ψ (see entry Two-State Vector Formalism), the weak value is [1]: O w ≡ Φ|O|Ψ Φ|Ψ. (1) Contrary to classical physics, variables in quantum mechanics might not have definite values at a give...
