Authenticated encryption (AE) is a cryptographic construction that simultaneously protects
confidentiality and integrity. A considerable amount of research has been devoted to the …

Thanks to the widespread deployment of TLS, users can access private data over channels
with end-to-end confidentiality and integrity. What they cannot do, however, is prove to third …

Big data drive multidimensional convergence and profound innovations among industries
and provide novel ways of exploring the world. As they significantly create economic and …

This paper provides efficient authenticated-encryption (AE) schemes in which a ciphertext is
a commitment to the key. These are extended, at minimal additional cost, to schemes where …

Message franking enables cryptographically verifiable reporting of abusive messages in end-
to-end encrypted messaging. Grubbs, Lu, and Ristenpart recently formalized the needed …

This paper initiates research on zero-knowledge middleboxes (ZKMBs). A ZKMB is a
network middlebox that enforces network usage policies on encrypted traffic. Clients send …

A core goal of the NIST PQC competition is to produce PKE schemes which, even if attacked
with a large-scale quantum computer, maintain the security guarantees needed by …

We provide a strong definition for committing authenticated-encryption (cAE), as well as a
framework that encompasses earlier and weaker definitions. The framework attends not only …

A common requirement in practice is to periodically rotate the keys used to encrypt stored
data. Systems used by Amazon and Google do so using a hybrid encryption technique …

End-to-end encryption (E2EE) poses a challenge for automated detection of harmful media,
such as child sexual abuse material and extremist content. The predominant approach at …
