However, cloud providers might also be a source for loss of confidentiality. We present a protocol to delegate computations into clouds with encrypted data. The protocol is based on homomorphic properties of encryption algorithms. The protocol can also be used to amend existing applications by software patches of binaries. We evaluate the protocol by a proof-of-concept implementation to investigate practicability, and discuss variants and extensions to increase the prototype's efficiency.<\/jats:p>","DOI":"10.1145\/2331576.2331583","type":"journal-article","created":{"date-parts":[[2012,7,13]],"date-time":"2012-07-13T23:07:36Z","timestamp":1342220856000},"page":"38-42","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Securing cloud-based computations against malicious providers"],"prefix":"10.1145","volume":"46","author":[{"given":"Adil","family":"Bouti","sequence":"first","affiliation":[{"name":"FernUniversit\u00e4t in Hagen, Hagen,Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Keller","sequence":"additional","affiliation":[{"name":"FernUniversit\u00e4t in Hagen, Hagen,Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,7,16]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1755688.1755695"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/PST.2008.12"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.5555\/1782574.1782604"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2090236.2090262"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.5555\/2033036.2033075"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-29011-4_27"},{"key":"e_1_2_1_8_1","first-page":"516","volume-title":"CRYPTO '85","author":"Desmedt Y.","year":"1986","unstructured":"Y.
