A New Security Cloud Storage Data Encryption Scheme Based on Identity Proxy Re-encryption
In the process of cloud data storage, data owner will encrypt data and upload it to the cloud, however, this method cannot support for encrypted data sharing. Especially, when data is shared with many users, the scalability is very weak. In order to solve this problem, we put forward a new security cloud storage data encryption scheme based on identity proxy re-encryption in this article. This ...
متن کاملIdentity-based data storage in cloud computing
Identity-based proxy re-encryption schemes have been proposed to shift the burden of managing numerous files from the owner to a proxy server. Nevertheless, the existing solutions suffer from several drawbacks. First, the access permission is determined by the central authority, which makes the scheme impractical. Second, they are insecure against collusion attacks. Finally, only queries from t...
متن کاملAuditing cloud storage for continuous storage security
Cloud storage permits users to remotely store their knowledge and revel in the on-demand top quality cloud applications while not the burden of native hardware and software package management. Though the advantages are clear, such a service is addition relinquishing users’ physical possession of their outsourced knowledge, which necessarily poses new security risks towards the correctness of th...
متن کاملIdentity Based Threshold Proxy Signature
Identity-based (ID-based) public key cryptosystem can be a good alternative for certificate-based public key setting, especially when efficient key management and moderate security are required. In a (t, n) threshold proxy signature scheme, the original signer delegates the power of signing messages to a designated proxy group of n members. Any t or more proxy signers of the group can cooperati...
متن کاملIdentity-Based Proxy Re-encryption
In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in the public-key setting. In this paper, we address the problem of Identity-Based proxy re-encryption, where ciphertexts are transformed from one identity to another. Our schemes are compatible with curr...
