What are the current limitations (and capabilities) of Functional Encryption used for access control?
I'm trying to make my way in Functional Encryption used for access control. I read a lot of papers such as "How to Run Turing Machines on Encrypted Data", "Functional Encryption: New Perspectives and ...
I am looking for a functional encryption scheme that can compute a linear function. I do not need to work with attributes. All I want is to compute the result of a function $y = a*x+b$, where $x$ is ...
To my best of knowledge, I have kown there exists randomized encoding scheme whose encoding circuit is in $NC^1$, fully homomorphic encryption scheme whose decryption circuit is in $NC^1$, and ...
FE - functional encryption PK - public key I want to design a PK cryptosystem that has a unique PK for each encryptor. Namely, the encryptor submits a unique value (or an attribute) to the private ...
