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

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

Secure and highly efficient authenticated encryption (AE) algorithms which achieve data
confidentiality and authenticity in the symmetric-key setting have existed for well over a …

At CCS 2015, Pereira et al. introduced a pragmatic model enabling the study of leakage-
resilient symmetric cryptographic primitives based on the minimal use of a leak-free …

Abstract At CCS 2015, Gueron and Lindell proposed GCM-SIV, a provably secure
authenticated encryption scheme that remains secure even if the nonce is repeated. While …

Abstract We study Authenticated Encryption with Associated Data (AEAD) from the viewpoint
of composition in arbitrary (single-stage) environments. We use the indifferentiability …

Currently, a vast majority of symmetric-key cryptographic schemes are built as block cipher
modes. The block cipher is designed to be hard to distinguish from a random permutation …

Abstract A Rugged Pseudorandom Permutation (RPRP) is a variable-input-length tweakable
cipher satisfying a security notion that is intermediate between tweakable PRP and …

Clarifying the robustness of authenticated encryption (AE) schemes, such as security under
nonce misuse or Release of Unverified Plaintext (RUP), is critically important due to the …

In the classical world, the XOR of pseudorandom permutations E_ k_1 ⊕ ⋯ ⊕ E_ k_r for r ≥
2 is a well-established way to design a pseudorandom function with “optimal” security …
