Portable Implementation of Postquantum Encryption Schemes and Key Exchange Protocols on JavaScript-Enabled Platforms
TL;DR: This work investigates and implements several recent lattice-based encryption schemes and public-key exchange protocols including Lizard, ring-Lizard, Kyber, Frodo, and NewHope in JavaScript, which are the active candidates of postquantum cryptography due to their applicabilities and efficiencies and shows that implementing lattices-based cryptography on JavaScript-enabled platforms is achievable and results in desirable portability.

Memory-Constrained Implementation of Lattice-based Encryption Scheme on the Standard Java Card Platform.
TL;DR: It is indicated that polynomial multiplication can be performed on Java Card efficiently even if the long integers are not supported, which makes running more lattice-based cryptosystems on smart cards achievable.
