In this paper, we analyze two proxy signatures scheme [1], [2] proposed by Lal and Awasthi and found that both the schemes suffer with the security flaws. The scheme [1] suffers with proxy signer’s forgery attacks and misuse of original signer’s delegated information. The other scheme [2] suffers with original signer’s forgery attack, proxy signer’s undeniability and misuse of delegated informa...

A new perspective is provided on the under-investment problem in the regulation of a rm with market power. We compare a political equilibrium based on a voting model with lobbying with a delegation equilibrium, where a government can delegate to a particular `type' of proor anti-industry regulator. Our analysis suggests two possible ways in which we may observe e ective, although second-best, p...

Generally, these agents have different information, different permissible control notices, and different preference orderings. These agents may act in complete in...

In the setting of cloud computing a user wishes to delegate its data, as well as computations over this data, to a cloud provider. Each computation may read and modify the data, and these modifications should persist between computations. Minding the computational resources of the cloud, delegated computations are modeled as RAM programs. In particular, the delegated computations’ running time ...

Abstract The usage of delegated legislation as a means governance deserves significant attention, in view the enormous impact that it is capable having on lives citizens.
