RSA-TBOS signcryption with proxy re-encryption [PDF]
Proceedings of the 8th ACM workshop on Digital rights management, 2008 The recent attack on Apple iTunes Digital Rights Management [17] has brought to light the usefulness of proxy re-encryption schemes for Digital Rights Management. It is known that the use of proxy re-encryption would have prevented the attack in [17]. With this utility in mind and with the added requirement of non-repudiation, we propose the first ever

Chosen-ciphertext secure proxy re-encryption [PDF]
Proceedings of the 14th ACM conference on Computer and communications security, 2007 In a proxy re-encryption (PRE) scheme, a proxy is given special information that allows it to translate a ciphertext under one key into a ciphertext of the same message under a different key. The proxy cannot, however, learn anything about the messages encrypted under either key.

DSAS: A Secure Data Sharing and Authorized Searchable Framework for e-Healthcare System
IEEE Access, 2022 In e-healthcare system, an increasing number of patients enjoy high-quality medical services by sharing encrypted personal healthcare records (PHRs) with doctors or medical research institutions. However, one of the important issues is that the encrypted

Identity-Based Proxy Re-encryption [PDF]
, 2007 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 identityto ...

Multi-key homomorphic proxy re-encryption scheme based on NTRU and its application
Tongxin xuebao, 2021 To improve the practicability of homomorphic encryption in the application of multi-user cloud computing, a NTRU-based multi-key homomorphic proxy re-encryption (MKH-PRE) scheme was constructed.Firstly, a new form of NTRU-based multi-key ciphertext was ...
