A Type-and-Identity-based Proxy Re-Encryption Scheme and its Application in Healthcare [PDF]
, 2008 Proxy re-encryption is a cryptographic primitive developed to delegate the decryption right from one party (the delegator) to another (the delegatee).

Ciphertext-Policy Attribute-Based Encryption
IEEE Symposium on Security and Privacy, 2007 In several distributed systems a user should only be able to access data if a user posses a certain set of credentials or attributes. Currently, the only method for enforcing such policies is to employ a trusted server to store the data and mediate ...

Fully homomorphic encryption using ideal lattices
Symposium on the Theory of Computing, 2009 We propose a fully homomorphic encryption scheme -- i.e., a scheme that allows one to evaluate circuits over encrypted data without being able to decrypt. Our solution comes in three steps.

International Journal of Information Security, 2022 Chaos-based cryptosystems have been an active area of research in recent years. Although these algorithms are not standardized like AES, DES, RSA, etc., chaos-based cryptosystems like Chebyshev polynomials can provide additional security when used with ...

Owner Specified Excessive Access Control for Attribute Based Encryption
IEEE Access, 2016 Attribute-based encryption (ABE) has emerged as a promising solution for access control to diverse set of users in cloud computing systems. Policy can just specify whether (or not) any specific user should be given access to data, but it lacks to provide

Similarity Calculation Based on Homomorphic Encryption [PDF]
, 2023 In recent years, although some homomorphic encryption algorithms have been proposed to provide additive homomorphic encryption and multiplicative homomorphic encryption. However, similarity measures are required for searches and queries under homomorphic encrypted ciphertexts.
