PAES: Policy-Based Authority Evaluation Scheme [chapter]

Enrico Scalavino, Vaibhav Gowadia, Emil C. Lupu
2009 Lecture Notes in Computer Science  
To address these limitations, we propose PAES: a Policy-based Authority Evaluation Scheme, which combines data protection with a distributed policy evaluation protocol.  ...  This permits distributing policy evaluation over a flexible set of authorities, simultaneously increasing the resilience of policy enforcement.  ...  To address these issues we propose a Policy-based Authority Evaluation Scheme (PAES).  ...

Dynamic Revenue Sharing

Santiago Balseiro, Max Lin, Vahab Mirrokni, Renato Paes Leme, Song Zuo
2017 Social Science Research Network  
In this paper, we characterize the optimal revenue sharing scheme that satisfies both constraints in expectation. Finally, we empirically evaluate our revenue sharing scheme on real data.  ...  In particular, we introduce dynamic revenue sharing schemes where we balance the two constraints over different auctions to achieve higher profit and seller revenue.  ...  ) based on the optimal relaxation solution.  ...

Time Based Policies The policy we will construct in the proof of Theorem 3.3 has the form of a time based policy, which we describe below.  ...  In Abolhassani et al. [2017] , the authors show how to design a 0.738-competitive policy for Θ(log n)-frequent instances.  ...  Similarly, we can consider the policy Π 2 where τ (π(2)) is also rounded down to (1 − c 2 ε)MAX for the nearest integer c 2 .  ...
