Ontology Based Privacy Preservation over Encrypted Data using Attribute-Based Encryption Technique

by Rubin Thottupurathu Jose and Sojan Lal Poulose

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 378–386, 2021; DOI: 10.25046/aj060244

Abstract:

The web documents are automatically interacting to discover the information by web mining, which is one of the applications of Cloud Computing (CC) technologies. These documents may be in the form of structured, semi-structured, or unstructured formats. In current web technologies, the Semantic Web is an extension for better enabling the people and computers to…

Short CCA-Secure Attribute-Based Encryption

by Hiroaki Anada and Seiko Arita

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 261–273, 2018; DOI: 10.25046/aj030132

Abstract:

Chosen-ciphertext attacks (CCA) are typical threat on public-key encryption schemes. We show direct chosen-ciphertext security modification in the case of attribute-based encryption (ABE), where an ABE scheme secure against chosen-plaintext attacks (CPA) is converted into an ABE scheme secure against CCA by individual techniques. Our modification works in the setting that the Diffie-Hellman tuple to…
