Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn
as the foundation for secure cryptographic systems. Attractive features of lattice cryptography …

The advent of quantum computing threatens to break many classical cryptographic
schemes, leading to innovations in public key cryptography that focus on post-quantum …

Lattice-based cryptographic primitives are believed to offer resilience against attacks by
quantum computers. We demonstrate the practicality of post-quantum key exchange by …

In recent years, lattice-based cryptography has been recognized for its many attractive
properties, such as strong provable security guarantees and apparent resistance to quantum …

This paper shows a generic and simple conversion from weak asymmetric and symmetric
encryption schemes into an asymmetric encryption scheme which is secure in a very strong …

The notion of non-malleable cryptography, an extension of semantically secure
cryptography, is defined. Informally, the additional requirement is that given the ciphertext it …

Identity-based encryption (IBE) is an exciting alternative to public-key encryption, as IBE
eliminates the need for a Public Key Infrastructure (PKI). The senders using an IBE do not …

The Supersingular Isogeny Key Encapsulation mechanism (SIKE) is the only post-quantum
key encapsulation protocol based on elliptic curves and isogeny maps between them …

Designing public key cryptosystems that resist attacks by quantum computers is an important
area of current cryptographic research and standardization. To retain confidentiality of …

In a proxy re-encryption scheme, a semi-trusted proxy can transform a ciphertext under
Alice's public key into another ciphertext that Bob can decrypt. However, the proxy cannot …
