Boosting Linearly-Homomorphic Encryption to Evaluate Degree-2 Functions on Encrypted Data
public-key cryptography homomorphic encryption
2016/1/6
We show a technique to transform a linearly-homomorphic encryption into a homomorphic
encryption scheme capable of evaluating degree-2 computations on ciphertexts. Our transformation is
surprisingly...
Linearly Homomorphic Encryption from DDH
Linearly Homomorphic Encryption Orders of Quadratic Fields
2016/1/4
We design a linearly homomorphic encryption scheme whose security relies on
the hardness of the decisional Diffie-Hellman problem. Our approach requires some special
features of the underlying group...
