Public Key Encryption with Learning With Errors (LWE)

Learning With Errors (LWE) is a quantum robust method of cryptography and which can also be used for homomorphic encryption. Initially we create a secret value (s) and which is our private key. We then create a public key which is based on random numbers (A), and then generate another set of numbers (B) which is based on A, s and random errors e.
