How to Quickly and Meaningfully Improve the Financial System's Collective Ability to Detect Crimes

Complex financial crimes are hard to detect primarily because data related to different pieces of the overall puzzle are usually distributed across a network of financial institutions, regulators, and law-enforcement agencies. 1,317 more words

Extending the Paillier Cryptosystem to Handle Floating Point Numbers

The Paillier Cryptosystem is a partial homomorphic encryption scheme that supports two important operations: addition of two encrypted integers and the multiplication of an encrypted… 891 more words

Sum of Encrypted Vectors

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


Can Data Scientists Predict the Financial Markets?

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

Using Paillier Library

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


RSA is partially cryptographically homomorphic

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


On dual lattice attacks against small-secret LWE and parameter choices in HElib and SEAL

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

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