Function-Hiding Inner Product Encryption Is Practical [PDF]

open access: yes, 2018
In a functional encryption scheme, secret keys are associated with functions and ciphertexts are associated with messages. Given a secret key for a function f, and a ciphertext for a message x, a decryptor learns f(x) and nothing else about x. Inner product encryption is a special case of functional encryption where both secret keys and ciphertext are ...

Lattice-Based Hierarchical Inner Product Encryption

open access: yes, 2012
The notion of inner-product encryption (IPE), introduced by Katz, Sahai, and Waters at Eurocrypt 2008, is a generalization of identity-based encryption in which ciphertexts and secret keys are associated to vectors in some finite field. In an IPE scheme, a ciphertext can only be decrypted by a secret key if the vector associated with the latter is ...

Adaptively Secure Inner Product Encryption from LWE [PDF]

open access: yes, 2020
Attribute-based encryption (ABE) is an advanced form of encryption scheme allowing for access policies to be embedded within the secret keys and ciphertexts. By now, we have ABEs supporting numerous types of policies based on hardness assumptions over bilinear maps and lattices. However, one of the distinguishing differences between ABEs based on these

Spatial Encryption Revisited: From Delegatable Multiple Inner Product Encryption and More [PDF]

open access: yes, 2022
Spatial encryption (SE), which involves encryption and decryption with affine/vector objects, was introduced by Boneh and Hamburg at Asiacrypt 2008. Since its introduction, SE has been shown as a versatile and elegant tool for implementing many other important primitives such as (Hierarchical) Identity-based Encryption ((H)IBE), Broadcast (H)IBE ...
