A Security Cloud Storage Scheme Based Accountable Key-Policy Attribute-Based Encryption without Key Escrow
With the development of cloud computing, more and more users start to utilize the cloud storage service. However, there exist some issues: 1) cloud server steals the shared data, 2) sharers collude with the cloud server to steal the shared data, 3) cloud server tampers the shared data, 4) sharers and key generation center (KGC) conspire to steal the shared data. In this paper, we use advanced e...
متن کاملKey-Policy Multi-authority Attribute-Based Encryption
Bilinear groups are often used to create Attribute-Based Encryption (ABE) algorithms. In particular, they have been used to create an ABE system with multi authorities, but limited to the ciphertext-policy instance. Here, for the first time, we propose two multi-authority key-policy ABE systems. In our first proposal, the authorities may be set up in any moment and without any coordination. A p...
متن کاملQuantum Key-Policy Attribute-Based Encryption
Attribute-Based Encryption is a relatively new concept in the field of cryptography, and it allows only the authorized entities to decrypt a message. This type of encryption is the mechanism by which the users may encrypt and decrypt data based on user attributes. This paper proposes the first quantum alternative of the scheme Key-Policy Attribute Based Encryption, where the information, the en...
متن کاملA key-policy attribute-based broadcast encryption
According to the broadcast encryption scheme with wide applications in the real world without considering its security and efficiency in the model simultaneously an “unbounded”, Key-Policy Attribute-Based Broadcast Encryption scheme(KP-ABBE) was proposed by combining with waters dual system encryption, attribute-based encryption and broadcast encryption system. Based on the standard model, the ...
متن کاملMulti-Owner Data Sharing Using Key Policy Attribute-Based Encryption Method in the cloud
There is a Major problem in public clouds about the sharing of documents on attribute based policies, sharing data in a dynamic groups . With the help of advantage of low maintenance, cloud computing gives the effective solution for sharing group resource among cloud users. As the sharing of documents with different keys like attribute based encryption (ABE), and/or proxy re-encryption (PRE) ap...
