Recently I received a question about what would be a good way to do the element wise summation between two encrypted vectors.

I have written before about how to do the secure sum of single values… 1,695 more words

It is evident that the study of data science and machine learning has revolutionized most, if not all, industries and it feels like every week a new state-of-the-art system is developed that breaks boundaries. 1,106 more words

The Paillier cryptosystem is a probabilistic asymmetric encryption scheme commonly cited in the literature related to encrypted databases. The main reason for that is the additive homomorphic property offered by it. 1,218 more words

Homomorphic cryptography [1], should it ever become available as a product, will have an intriguing property: computers will be able to operate on encrypted data without either having to- or being able to decrypt it. 269 more words

My paper on solving small, sparse secret instances is now on ePrint. Here’s the abstract:

331 more wordsWe present novel variants of the dual-lattice attack against LWE in the presence of an unusually short secret.
