Traceable ciphertext-policy attribute-based encryption scheme with attribute level user revocation for cloud storage. [PDF]
PLoS ONE, 2018 In a ciphertext-policy attribute-based encryption (CP-ABE) scheme, a user may have multiple attributes, and each attribute may be shared simultaneously by many users. The decryption key of an attribute can thus be shared by many users who all possess the

SKENO: Secret key encryption with non-interactive opening
Journal of Mathematical Cryptology, 2015 In this paper, we introduce the notion of secret key encryption with non-interactive opening (SKENO). With SKENO, one can make a non-interactive proof π to show that the decryption result of a ciphertext C under a shared secret key K is indeed plaintext ...

Key Distribution System Based on Hadamard Designs
Моделирование и анализ информационных систем, 2019 The problem of key distribution in a community for providing secure communication between its participants is studied. To solve this problem, key predistribution systems can be used, in which each user receives some key information that can later be used
