The Geometry of Provable Security: Some Proofs of Security in Which Lattices Make a Surprise Appearance
TL;DR: This work focuses on RSA-OAEP, the Rabin partial-domain hash signature scheme, techniques to compress Rabin signatures and ciphertexts, the relationship between the RSA and Paillier problems and Hensel lifting, and the hardness of the most significant bits of a Diffie–Hellman secret.

Random-index PIR and Applications
TL;DR: Random-index PIR (RPIR) as mentioned in this paper is a weaker variant of PIR, where the retrieved index is an output rather than an input of the protocol, and is chosen at random.

Functional Encryption Without Obfuscation
TL;DR: In the weaker selective security model, where the adversary is forced to specify its target before seeing the public parameters, full security can be obtained but at the cost of an exponential loss in the security reduction.

Discrete Gaussian Leftover Hash Lemma over Infinite Domains
TL;DR: In this article, a lattice-world analog of the LHL over infinite domains is presented, where certain generalized subset sum distributions are statistically close to well behaved discrete Gaussian distributions, even without any modular reduction.

Candidate Multilinear Maps from Ideal Lattices
TL;DR: In this paper, the authors describe plausible lattice-based constructions with properties that approximate the sought-after multilinear maps in hard-discrete-logarithm groups and show an example application of such multi-linear maps that can be realized using their approximation.
