Witryna6 gru 2024 · Order-preserving encryption (OPE) that preserves the numerical ordering of plaintexts is one of the promising solutions of cloud security. In 2013, an … Witrynaunless using specific encryption algorithms or mode of operation (e.g., order preserving encryption, ECB mode of operation preserving equality, see below), indexing encrypted data is useless. For both strategies, data is decrypted on the database server at runtime. Thus, the encryption keys must be transmitted or kept …

Order-preserving Encryption as a Tool for Privacy-Preserving …
http://www.fkerschbaum.org/ccs15.pdf WitrynaA startup is marketing a novel public-key deterministic order-preserving encryp- tion scheme. More precisely, messages and ciphertexts can be viewed as numbers and the ciphertexts preserve the order of the plaintexts. Namely, for every pk and every M,,M, if Mi < M2, then Epk (M) < Epk (14), if M1 = M, then Epk (M) Epk (M2). WitrynaSecuring DICOM images is essential to protect the privacy of patients, especially in the era of telemedicine and eHealth/mHealth. This increases the demand for rapid security. Nevertheless, a limited amount of research work has been conducted to ensure the security of DICOM images while minimizing the processing time. Hence, this paper … mary the great white shark
