Fully Secure and Succinct Attribute Based Encryption for Circuits from Multi-linear Maps
Attribute-based encryption for circuits Full security Multi-linear maps
2016/1/7
We propose new fully secure attribute based encryption (ABE) systems for polynomialsize
circuits in both key-policy and ciphertext-policy flavors. All the previous ABE systems
for circuits were prov...
In an attribute-based encryption (ABE) scheme, a ciphertext is associated with an L-bit public index IND and a message m, and a secret key is associated with a Boolean predicate P. The secret key allo...
Attribute-Based Encryption for Circuits from Multilinear Maps

In this work, we provide the first construction of Attribute-Based Encryption (ABE) for general circuits. Our construction is based on the existence of multilinear maps. We prove selective security of...
