Nowadays, finding genetic components and determining the likelihood that treatment would
be helpful for patients are the key issues in the medical field. Medical data storage in a …

Attribute-based encryption (ABE) enables fine-grained access control on encrypted data and
has a large number of practical applications. This paper presents FABEO: faster pairing …

In this paper, we study efficient and authorized rewriting of transactions already written to a
blockchain. Mutable transactions will make a fraction of all blockchain transactions, but will …

Ateniese et al. introduced the primitive of matchmaking encryption (ME) at CRYPTO 2019
and left open several important questions, which include extending ME to fuzzy cases or …

Measuring efficiency is difficult. In the last decades, several works have contributed in the
quest to successfully determine and compare the efficiency of pairing-based attribute-based …

Attribute-based encryption (ABE) cryptographically implements fine-grained access control
on data. As such, data can be stored by an entity that is not necessarily trusted to enforce …

Decentralized multi-authority attribute-based encryption (MA-ABE) is a strengthening of
standard ciphertext-policy attribute-based encryption so that there is no trusted central …

Abstract At Eurocrypt'19, Attrapadung presented several transformations that dynamically
compose a set of attribute-based encryption (ABE) schemes for simpler predicates into a …

TLS termination, which is essential to network and security infrastructure providers, is an
extremely latency-sensitive operation that benefits from access to sensitive key material …

Decentralized multi-authority attribute-based encryption (𝖬𝖠-𝖠𝖡𝖤) is a strengthening of
standard ciphertext-policy attribute-based encryption so that there is no trusted central …
