Towards Low-Energy Leakage-Resistant Authenticated Encryption from the Duplex Sponge Construction

Chun Guo, Olivier Pereira, Thomas Peters, François-Xavier Standaert
2020 IACR Transactions on Symmetric Cryptology  
., ≈ 2c/2, under an assumption of non-invertible leakage.  ...  We also provides the first rigorous methodology for the leakage-resistance of sponge/duplex-based AEs based on a minimal non-invertibility assumption on leakages, which leads to various insights on designs  ...  This work has been funded in parts by the European Union through the ERC project SWORD (724725), and the European Union and Walloon Region FEDER USERMedia project 501907-379156.  ...

INT-RUP Secure Lightweight Parallel AE Modes

Avik Chakraborti, Nilanjan Datta, Ashwin Jha, Cuauhtemoc Mancillas-López, Mridul Nandi, Yu Sasaki
2020 IACR Transactions on Symmetric Cryptology  
Specific to authenticated encryption (AE), the NIST draft demands that the scheme should have one primary member that has key length of 128 bits, and it should be secure for at least 250 − 1 byte queries  ...  In this paper, we propose two new designs for lightweight AE modes, called LOCUS and LOTUS, structurally similar to OCB and OTR, respectively.  ...  Nilanjan Datta, Ashwin Jha and Mridul Nandi are supported by the project "Study and Analysis of IoT Security" under Government of India at R.C.Bose Centre for Cryptology and Security, Indian Statistical  ...

Key Prediction Security of Keyed Sponges

Bart Mennink
2018 IACR Transactions on Symmetric Cryptology  
We take closer inspection at the key prediction security of the sponge and close the remaining gap in the existing security analysis: we confirm key security up to close to 2k, regardless of the rate.  ...  The keyed sponge is a well-accepted method for message authentication. It processes data at a certain rate by sequential evaluation of an underlying permutation.  ...  Beyond the keyed sponges and keyed duplexes, key prediction security also appears in the analyses of HMAC-SHA-3 [NW16] and the sandwich sponge [Nai16] .  ...
