A Bit-fixing PRF with O(1) Collusion-Resistance from LWE
Constrained PRF Collusion-resistance LWE
2018/11/9
Constrained pseudorandom functions (CPRFs) allow learning modified PRF keys that can evaluate the PRF on a subset of the input space, or based on some sort of predicate. First introduced by Boneh and ...
Note on Constructing Constrained PRFs from OWFs with Constant Collusion Resistance
Constrained PRF collusion-resistance one-way functions
2018/11/8
Constrained pseudorandom functions (CPRFs) are a type of PRFs that allows one to derive a constrained key KCKC from the master key KK. While the master key KK allows one to evaluate on any input as a ...
Constrained PRFs for Bit-fixing from OWFs with Constant Collusion Resistance
Constrained PRF Collusion-resistance One-way functions
2018/11/5
Constrained pseudorandom functions (CPRFs) allow learning `constrained' PRF keys that can evaluate the PRF on a subset of the input space, or based on some sort of predicate. First introduced by Boneh...
Compactness vs Collusion Resistance in Functional Encryption
Functional encryption reduction compact
2016/6/6
We present two general constructions that can be used to combine any two functional encryption
(FE) schemes (supporting a bounded number of key queries) into a new functional encryption scheme
suppo...
Privacy-Enhanced Participatory Sensing with Collusion Resistance and Data Aggregation
privacy participatory sensing collusion resistance
2016/1/9
Participatory sensing enables new paradigms and markets for information collection based on the ubiquitous availability of smartphones, but also introduces privacy challenges for participating users a...
Attribute-Based Signatures:Achieving Attribute-Privacy and Collusion-Resistance
Attribute-Based Signatures Achieving Attribute-Privacy Collusion-Resistance
2009/6/5
We introduce a new and versatile cryptographic primitive called Attribute-Based Signatures
(ABS), in which a signature attests not to the identity of the individual who endorsed a message,but instead...
