TinyIBE: identity-based encryption for heterogeneous sensor networks [PDF]

, 2009
The area of security for heterogeneous sensor networks (HSNs) is still an open research field that requires new cryptographic solutions. Recent results have demonstrated that elliptic curve cryptography (ECC) and pairing-based cryptography (PBC) are ...

Practical Attacks on Full-round FRIET

IACR Transactions on Symmetric Cryptology, 2022
FRIET is a duplex-based authenticated encryption scheme proposed at EUROCRYPT 2020. It follows a novel design approach for built-in countermeasures against fault attacks.

Forgery attacks on ++AE authenticated encryption mode

, 2016
In this paper, we analyse a block cipher mode of operation submitted in 2014 to the cryptographic competition for authenticated encryption (CAESAR). This mode is designed by Recacha and called ++AE (plus-plus-ae).

Public-Key Authenticated Encryption with Keyword Search Made Easy [PDF]

Public-key searchable encryption allows keyword-associated tokens to be used to test if a ciphertext contains specific keywords. Due to the low entropies of keywords, the token holder can create ciphertexts from candidate keywords and test them using

Low-energy symmetric key distribution in wireless sensor networks [PDF]

, 2011
In this work a scheme for key distribution and network access in a Wireless Sensor Network (WSN) that utilises Identity- Based Cryptography (IBC) is presented.

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 ...

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 ...

ISAP – Towards Side-Channel Secure Authenticated Encryption

IACR Transactions on Symmetric Cryptology, 2017
Side-channel attacks and in particular differential power analysis (DPA) attacks pose a serious threat to cryptographic implementations. One approach to counteract such attacks are cryptographic schemes based on fresh re-keying. In settings of pre-shared
