Once algorithms for quantum-resistant key exchange and digital signature schemes are
selected by standards bodies, adoption of post-quantum cryptography will depend on …

Using multiple, individual encryption schemes is a well-established method to increase the
overall security of encrypted data. These so-called multiple encryption or hybrid schemes …

Concerns about the impact of quantum computers on currently deployed public key
cryptography have instigated research into not only quantum-resistant cryptographic …

Encryption of data using multiple, independent encryption schemes (“multiple encryption”)
has been suggested in a variety of contexts, and can be used, for example, to protect against …

Certificateless cryptography (CL-PKC) is a concept that aims at enjoying the advantages of
identity based cryptography without suffering from its inherent key escrow. Several methods …

Key-encapsulation mechanisms (KEMs) are a common stepping stone for constructing
public-key encryption. Secure KEMs can be built from diverse assumptions, including ones …

In this paper, we discuss non-interactive updating of decryption keys in identity-based
encryption (IBE). In practice, key revocation is a necessary and inevitable process and IBE is …

Weng et al. introduced the notion of conditional proxy re-encryption (or C-PRE, for short),
whereby only the ciphertext satisfying one condition set by the delegator can be transformed …

Abstract Hybrid Authenticated Key Exchange (AKE) protocols combine keying material from
different sources (post-quantum, classical, and quantum key distribution (QKD)) to build …

Paterson and Quaglia (SCN 2010) proposed the concept of time-specific encryption (TSE)
and its efficient constructions. TSE is a type of public key encryption with additional …
