Learning With Errors (LWE) is a quantum robust method of cryptography. 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. In this case we will show how a 4-bit value can be encrypted. In this case we will convert…
