Efficient Rijndael Encryption Implementation with Composite Field Arithmetic

TL;DR: This work explores the use of subfield arithmetic for efficient implementations of Galois Field arithmetic especially in the context of the Rijndael block cipher and describes how to select a representation which minimizes the computation cost of the relevant arithmetic.

Online learning in online auctions

TL;DR: It is demonstrated that results from online learning can be usefully applied in this context, and a new auction for digital goods is derived that achieves a constant competitive ratio with respect to the optimal (offline) fixed price revenue.

Online learning in online auctions

TL;DR: In this paper, the authors consider the problem of revenue maximization in online auctions, and derive a new auction for digital goods that achieves a constant competitive ratio with respect to the optimal (offline) fixed price revenue.

Efficient rijndael encryption implementation with composite field arithmetic

TL;DR: In this paper, the authors explore the use of subfield arithmetic for efficient implementations of Galois Field arithmetic especially in the context of the Rijndael block cipher, and propose a technique that involves mapping field elements to a composite field representation.

Managing a cluster of networked resources and resource groups using rule - base constraints in a scalable clustering environment

TL;DR: In this paper, a method of managing a cluster of networked resources and resource groups using rule-based constraints is presented. But it does not address the problem of resource availability and quality of service.
