FNR: Arbitrary Length Small Domain Block Cipher Proposal [chapter]

Sashank Dara, Scott Fluhrer
2014 Lecture Notes in Computer Science  
We propose a practical flexible (or arbitrary) length small domain block cipher, FNR encryption scheme. FNR denotes Flexible Naor and Reingold.  ...  It can cipher small domain data formats like IPv4, Port numbers, MAC Addresses, Credit card numbers, any random short strings while preserving their input length.  ...  Expansion of ciphertext length may be undesirable for said reasons. Small domain block ciphers are useful tool in designing privacy of sensitive data fields of smaller length (<128 bits).  ...

Efficient Format Preserving encrypted databases

Prakruti Chandrashekar, Sashank Dara, V. N. Muralidhara
2015 2015 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)  
We propose storage efficient SQL-aware encrypted databases that preserve the format of the fields. We give experimental results of storage improvements in CryptDB using FNR encryption scheme.  ...  Here both c, p are in same domain. FNR is a arbitrary length small domain block cipher proposed in [3] .  ...  FNR scheme could be used to preserve the format and length of arbitrary length small domain sensitive data like MAC addresses, IPV4(32), IPV6(32) etc.  ...

Efficient Masking of ARX-Based Block Ciphers Using Carry-Save Addition on Boolean Shares [chapter]

Daniel Dinu, Johann Großschädl, Yann Le Corre
2017 Lecture Notes in Computer Science  
Masking is a widely-used technique to protect block ciphers and other symmetric cryptosystems against Differential Power Analysis (DPA) attacks.  ...  Supported by FNR Luxembourg (CORE project ACRYPT, ID C12-15-4009992).  ...  This idea was originally proposed for hardware implementation [1] , but can also be applied to protect software implementations of ARX-based block ciphers against DPA as demonstrated in [12] .  ...

Efficient Lifting for Shorter Zero-Knowledge Proofs and Post-Quantum Signatures [article]

Daniel Kales, Greg Zaverucha
2022 IACR Cryptology ePrint Archive  
Using a combination of these strategies at different points in the protocol, we design two new proof systems well suited to small circuits defined over small fields.  ...  In recent proofs the soundness depends on the size F, and small fields require more parallel repetitions, and therefore produce larger proofs.  ...  This generalizes to OWFs based on Even-Mansour (EM) block ciphers.  ...
