Policy-based Non-interactive Outsourcing of Computation using Multikey FHE and CP-ABE

2013 Proceedings of the 10th International Conference on Security and Cryptography   unpublished
We then present a generic construction using CP-ABE and multikey Fully-Homomorphic encryption (FHE).  ...  There has been limited success so far achieving homomorphic encryption in the functional setting; that is, for primitives such as Ciphertext-Policy Attribute Based Encryption (CP-ABE) and Identity Based  ...  Acknowledgments We would like to thank the anonymous reviewers of SECRYPT 2013 for their helpful suggestions.  ...

2020 arXiv   pre-print
Due to the sensitivity of genomic data, these data should be encrypted using different keys. However, supporting computation on ciphertexts encrypted under multiple keys is a non-trivial task.  ...  New cryptographic techniques such as homomorphic encryption (HE) allow computations to be outsourced to and evaluated blindfolded in a resourceful cloud.  ...  In general, there are two types of ABE schemes based on where and Ciphertext-policy (CP-ABE) [11] .  ...
