Guidelines |
One of the possible simplifying approaches to lattice-based cryptography is using ideal lattices. After briefly describing the basic ideas of lattice-based cryptography (e.g., from [MR]), the student will cover the basics of ideal lattices and the algorithm for deciding if a given lattice is ideal [DL]; she will give full details of the proofs and provide more examples. She will then extend these results to NTRU lattices [CS], [DL, Section 2.7]. The student may further potentially consider the application to efficient collision-resistant hash functions [MR, Section 4]. |
