At present, the access control schemes in the power grid are centralized. In the centralized system, the data of the network sensor nodes is transmitted by centralized nodes, and the data itself may b...
A cryptosystem for granting/rescinding access permission is proposed, based on elliptic curve cryptography. The `Organizational Cryptosystem' grants access permission not by giving secret (decription)...
The Internet of Things (IoT) technology has expanded widely across the world, promising new data management opportunities for industries, companies and individuals in different sectors, such as health...
Consider an access policy for some resource which only allows access to users of the system who own a certain set of attributes. Specifically, we consider the case where such an access structure is de...
This paper presents Hermes a practical data security scheme with a reference implementation, which enables distributed sharing and collaboration, enforcing access control with the help of cryptograp...
Proxy Re-Encryption (PRE) allows a ciphertext encrypted under Alice's public key to be transformed to an encryption under Bob's public key without revealing either the plaintext or the decryption keys...
Functional encryption enables fine-grained access to encrypted data. In many scenarios, however, it is important to control not only what users are allowed to read (as provided by traditional function...
Access control encryption (ACE) was proposed by Damgård et al. to enable the control of information flow between several parties according to a given policy specifying which parties are, or are n...
Fine-grained access control, especially in shared data environments such as the cloud, is a common scenario. Suppose a data owner encrypts and stores a collection of NN documents in the cloud, and wis...
In this work we investigate the problem of using public consensus networks -- exemplified by systems like Ethereum and Bitcoin -- to perform cryptographic functionalities that involve the manipulation...
Access Control Encryption (ACE) is a novel paradigm for encryption which allows to control not only what users in the system are allowed to \emph{read} but also what they are allowed to \emph{write}.
The Extended Access Control (EAC) protocol allows to create a shared cryptographic key between a client and a server. It is for instance referenced by the International Civil Aviation Organization for...
Enabling access controls for data hosted on untrusted cloud is attractive for many users and organizations. Recently, many works have been proposed to use advanced cryptographic primitives such as ide...
In cryptographic access control sensitive data is protected by cryptographic primitives and the desired access structure is enforced through appropriate management of the secret keys. In this paper we...
How to flexibly change the access policy after the initial data access policy has been set is a critical problem to promote attribute-based encryption (ABE) from a theoretical tool to a practical to...
