Abstract :
We first introduce some basic problems in lattice-based cryptography. Then we show how multibit LWE-based cryptosystem and IBE system can be constructed on them. According to the method put forward by D. Boneh et. al., we construct a public key cryptosystem from the IBE system. The cryptosystem is CCA-secure.
