Adversarially Robust Property Preserving Hash Functions
Hash function compression property-preserving
2018/12/3
Property-preserving hash functions are usually probabilistic: they use the random choice of a hash function from a family to achieve compression, and as a consequence, err on some inputs. Traditionall...
At Eurocrypt'12, Pandey and Rouselakis proposed the notion of property preserving symmetric encryption (PPEnc). They defined several security notions for PPEnc and studied their relationship. They als...
Function Private Functional Encryption and Property Preserving Encryption : New Definitions and Positive Results
Functional Encryption Property Preserving Encryption
2014/3/6
This work furthers the exploration of meaningful definitions for security of Functional Encryption. We propose new simulation based definitions for function privacy in addition to data privacy and stu...
Multi-property-preserving Domain Extension Using Polynomial-based Modes of Operation
Multi-property-preserving Domain Extension Polynomial-based Modes Operation
2010/3/16
In this paper, we propose a new double-piped mode of operation for multi-
property-preserving domain extension of MACs (message authentication codes), PRFs (pseu-
dorandom functions) and PROs (pseud...
Multi-Property-Preserving Hash Domain Extension and the EMD Transform
Hash functions random oracle collision-resistance
2008/12/29
We point out that the seemingly strong pseudorandom oracle preserving (PRO-Pr) property
of hash function domain-extension transforms defined and implemented by Coron et. al. [12] can
actually weaken...
Seven-Property-Preserving Iterated Hashing: ROX
Cryptographic hash functions Merkle-Damgard collision resistance preimage resistance
2008/8/28
Nearly all modern hash functions are constructed by iterating a compression function. At FSE'04,Rogaway and Shrimpton [RS04] formalized seven security notions for hash functions: collision resistance ...
Compression Functions Suitable for the Multi-Property-Preserving Transform
Compression Functions the Multi-Property-Preserving Transform standard hash functions
2008/6/2
Since Bellare and Ristenpart showed a multi-property preserving domain extension transform,the problem of the construction for multi-property hash functions has been reduced to that of the constructio...
