Homomorphic encryption is a form of encryption which allows various types of computations to be carried out on ciphertext and generate an encrypted result which, when decrypted, matches the result of operations performed on the plaintext. This is a desirable feature in modern communication system architectures. Homomorphic encryption would allow chaining together different services without exposing the data to each of those services. The homomorphic property of various cryptosystems can be used, in particular, to create private information retrieval schemes and enable widespread use of cloud computing by ensuring the confidentiality of processed data. In this talk, I will present an efficient Fully Homomorphic Encryption (FHE) scheme using non-commutative algebraic structure. I will also discuss applications that enables doing various machine learning and statistical analysis over encrypted big data. This is a joint work with V. Shpilrain.
