Multi-key homomorphic proxy re-encryption scheme based on NTRU and its application

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 proposed based on the idea of ciphertext extens...
