The notion of multi-authority attribute based encryption was introduced by Chase in TCC 2007. In this paper, we improve Chase’s scheme to allow encryptors to determine how many attributes are required for each ciphertext from related attribute authorities. The proposed scheme can be seen as a multi-trapdoor construction. Furthermore, we apply the LMSSS to outsource the decryption of multi-autho...

Multi-attribute auctions play a very important role in our economy: (i) they are widely used in industry procurement; (ii) many markets for services are organized in a form reminiscent of private multi-attribute auctions; (iii) recently many Internetbased markets adopted multi-attribute structure. Multi-attribute auctions differ from standard low price auctions in that (a) a buyer chooses a win...

This study develops a procedure for performing multi-attribute decision-making ship structural design of multi-purpose ship. The already designed is further structurally to comply with the requirements Classification Societies. hull and components are verified against yielding, buckling, ultimate strength. Based on limit state (ULS), first order reliability method (FORM) employed analyse risk i...

A framework for a multi-attribute multi-source data fusion is described. Uncertainty of data is modeled by fuzzy sets. The problem is considered on a general level. Credibility of sources, compatibility of data, as well as their reasonableness, are taken into consideration. The proposed method is illustrated by an example.
