Retrofitting Leakage Resilient Authenticated Encryption to Microcontrollers

Transactions on Cryptographic Hardware and Embedded Systems, 2020
The security of Internet of Things (IoT) devices relies on fundamental concepts such as cryptographically protected firmware updates. In this context attackers usually have physical access to a device and therefore side-channel attacks have to be ...

ESTATE: A Lightweight and Low Energy Authenticated Encryption Mode

IACR Transactions on Symmetric Cryptology, 2020
NIST has recently initiated a standardization project for efficient lightweight authenticated encryption schemes. SUNDAE, a candidate in this project, achieves optimal state size which results in low circuit overhead on top of the underlying block cipher.

Encryption Algorithm MLOL: Security and Efficiency Enhancement Based on the LOL Framework

Cryptography
Authenticated encryption with associated data (AEAD) schemes based on stream ciphers, such as ASCON and MORUS, typically use nonlinear feedback shift registers (NFSRs) and linear feedback shift registers (LFSRs) to generate variable-length key streams ...

Multi-Keyword Certificateless Searchable Public Key Authenticated Encryption Scheme Based on Blockchain

IEEE Access, 2020
As a quite attractive secure search mechanism in cloud environments, searchable encryption allows encrypted files to be searched by keyword and does not reveal any information about original data files.

How to reuse a one-time pad and other notes on authentication, encryption and protection of quantum information [PDF]

, 2005
Quantum information is a valuable resource which can be encrypted in order to protect it. We consider the size of the one-time pad that is needed to protect quantum information in a number of cases.

High-level Cryptographic Abstractions

, 2019
The interfaces exposed by commonly used cryptographic libraries are clumsy, complicated, and assume an understanding of cryptographic algorithms. The challenge is to design high-level abstractions that require minimum knowledge and effort to use while ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

ClaimChain: Improving the Security and Privacy of In-band Key Distribution for Messaging [PDF]

, 2018
The social demand for email end-to-end encryption is barely supported by mainstream service providers. Autocrypt is a new community-driven open specification for e-mail encryption that attempts to respond to this demand.
