Homomorphic MACs: MAC-Based Integrity for Network Coding
Network Coding MAC-Based Integrity
2015/8/5
Network coding has been shown to improve the capacity and robustness in networks. However, since intermediate nodes modify packets en-route, integrity of data cannot be checked using traditional MACs ...
Homomorphic Signatures for Polynomial Functions
Polynomial Functions Homomorphic Signatures
2015/8/5
We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an efficient algorithm t...
Linearly homomorphic signatures over binary fields and new tools for lattice-based signatures
binary fields lattice-based signatures
2015/8/5
Our scheme can be used to authenticate linear transformations of signed data, such as those arising when computing mean and least squares fit or in networks that use network coding. Our construction g...
Private Database Queries Using Somewhat Homomorphic Encryption
Somewhat Homomorphic Encryption Database
2015/8/5
In a private database query system, a client issues queries to a database and obtains the results without learning anything else about the database and without the server learning the query. While pre...
Targeted malleability: homomorphic encryption for restricted computations
restricted computations homomorphic encryption
2015/8/5
We put forward the notion of targeted malleability: given a homomorphic encryption scheme, in various scenarios we would like to restrict the homomorphic computations one can perform on encrypted data...
Fully Key-Homomorphic Encryption, Arithmetic Circuit ABE, and Compact Garbled Circuits
Arithmetic Circuit ABE Compact Garbled Circuits
2015/8/5
We construct the rst (key-policy) attribute-based encryption (ABE) system with short
secret keys: the size of keys in our system depends only on the depth of the policy circuit,
not its size. Our c...
The Effect of Some Agronomic Factors on the Amount and Quality of Homomorphic Fibre
homomorphic fibres hemp agronomic factors quality
2009/2/6
Due to overproduction of food in the agriculture sector, the cultivation of plants which can yield renewable raw materials for industry is increasing in importance. One such plant is hemp, which can b...
Illumination Transfer Using Homomorphic Wavelet Filtering and Its Application to Light-Insensitive Face Recognition
Homomorphic Wavelet Filtering Light-Insensitive Face Recognition
2010/12/17
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image)to another face image (refere...

2013/7/17
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image) to another face image (refer...
