It has been shown that the reward of a large malicious mining pool can be significantly increased by deviating from the honest mining strategy. Moreover, a malicious pool can launch the block withholdi

Full Database Reconstruction with Access and Search Pattern Leakage servers. In order to protect the confidentiality of data in the cloud, a database can be stored in encrypted form and all queries can be executed on the encrypted database. Recent research results suggest that a curious cloud provider may be able to decrypt some of the items in the database after s
