Asynchronous Verifiable Information Dispersal
2005We consider the distribution of data by a client among a set of n storage servers, of which up to t might be faulty exhibiting arbitrary, i.e., Byzantine, behavior. The goal is to ensure that clients can always recover the stored data correctly, independently from the behavior of faulty servers or other, faulty clients. An inefficient solution is based

Holographic dispersal and recovery of information
IEEE Transactions on Information Theory, 1989A simple scheme for dispersal and recovery of digital information based on the discrete Fourier transform is discussed. The author presents a different implementation of M.O. Rabin's (J. ACM, vol.36, no.2, p.335-48, Apr. 1989) scheme, whose recovery cost is O(log m+k) operations per character, assuming m= Theta (n); for example, when k= Theta (log n ...

Price dispersion, information and learning
Journal of Monetary Economics, 2006Abstract We consider an economy where trade is decentralized and agents have incomplete information with respect to the value of money. Agents’ learning evolves from private experiences and we explore how the formation of prices interacts with learning.

The Role of Dispersed Information in Inflation and Inflation Expectations
SSRN Electronic Journal, 2020We solve a rational expectations model of price formation with nominal rigidity and information frictions analytically to study how dispersed information impacts inflation and inflation expectations, without imposing strong structural assumptions on the aggregate marginal cost. The closed-form solution implies an ARMA(1,1) nowcast error and an ARMA(1,2)

Information Dispersal and Parallel Computation
1993In 1989, Michael Rabin proposed a fundamentally new approach to the problems of fault-tolerant routing and memory management in parallel computation, based on the idea of information dispersal. Yuh-Dauh Lyuu developed this idea in a number of new and exciting ways in his PhD thesis.

Platform competition under dispersed information [PDF]
, 2013 We study monopolistic and competitive pricing in a two-sided market where agents have incomplete information about the quality of the product provided by each platform. The analysis is carried out within a global-game framework that offers the convenience of equilibrium uniqueness while permitting the outcome of such equilibrium to depend on the ...

Dispersed Information and CEO Incentives
SSRN Electronic Journal, 2014I measure the social cost of stock-based compensation schemes in a model in which the CEO learns from market prices. In my model, all agents commit a small correlated error when forming their expectations about future productivity. The equilibrium stock price thus aggregates private information with noise.

Securing cloud data using information dispersal
2016 14th Annual Conference on Privacy, Security and Trust (PST), 2016The open nature and outsourced model of cloud computing, coupled with increasing sophistication of cyber attackers and rapid advancement in quantum computing, mandates a more adaptive and flexible approach to cloud data security. In this paper, we introduce a secure cloud storage system which can be layered transparently on existing public & private ...

Dispersion of Information and Bureaucratic Equilibrium
SSRN Electronic Journal, 2008The benefits’ valuation of a public good is a complex procedure. Many benefits are external benefits. In other cases the perceived benefits are contingent on the individual condition or they will be perceived in a future time. A complete valuation needs a lot of information about the public good’s characteristics.

Comparative Performance Analysis of Information Dispersal Methods
2019 24th Conference of Open Innovations Association (FRUCT), 2019In this paper, we present an analysis of information dispersal methods for using in distributed storage systems, processing, and transmission of data. We provide a comparative study of the methods most widely used in practice considering performance, reliability and cryptographic security.
