We formalize and analyze the general suffix keyed sponge construction, a pseudorandom function built on top of a cryptographic permutation. The construction hashes its data using the (keyless) sponge ...
Towards Lightweight Side-Channel Security and the Leakage-Resilience of the Duplex Sponge
Authenticated Encryption Duplex Construction Leakage-Resilience
2019/3/1
Authenticated Encryption (AE) has become the de facto standard for encryption in modern protocols, and the ubiquitous deployment of small connected devices naturally calls for the availability of ligh...

Conditional Cube Attack on Reduced-Round Keccak Sponge Function
Keccak-MAC Keyak cube tester
2016/12/10
The security analysis of Keccak, the winner of SHA-3, has attracted considerable interest. Recently, some attention has been paid to the analysis of keyed modes of Keccak sponge function. As a notable...
A Robust and Sponge-Like PRNG with Improved Efficiency
sponge pseudo-random number generator (PRNG) Patarin's H-coefficient technique
2016/12/9
Ever since Keccak won the SHA3 competition, sponge-based
constructions are being suggested for many different applications, including
pseudo-random number generators (PRNGs). Sponges are very
desir...
We present the Bash family of hashing algorithms based on the sponge paradigm.
A core element of this family is the Bash-f sponge function which refers to the LRX (LogicalRotation-Xor)
class of symm...
We study the problem of devising provably secure PRNGs
with input based on the sponge paradigm. Such constructions are very
appealing, as efficient software/hardware implementations of SHA-3 can
ea...
Practical Complexity Cube Attacks on Round-Reduced Keccak Sponge Function
Keccak SHA-3 sponge function
2016/1/23
In this paper we mount the cube attack on the Keccak sponge function. The cube attack, formally introduced in 2008, is an algebraic technique applicable to cryptographic primitives whose output can ...
Beyond 2^{c/2} Security in Sponge-Based Authenticated Encryption Modes
Authenticated encryption CAESAR Ascon
2016/1/9
The Sponge function is known to achieve 2^{c/2} security, where c is its capacity. This bound was carried over to keyed variants of the function, such as SpongeWrap, to achieve a min{2^{c/2},2^kappa} ...

Keccak SHA-3 sponge function
2016/1/7
In this paper, we comprehensively study the resistance of keyed variants of SHA-3 (Keccak) against algebraic attacks. This analysis covers a wide range of key recovery, MAC forgery and other types of ...

SCA Lightweight Cryptography Sponge functions
2016/1/3
PHOTON is a lightweight hash function which was proposed
by Guo et al. in CRYPTO 2011. This is used in low-resource ubiquitous
computing devices such as RFID tags, wireless sensor nodes, smart cards...

OAEP Sponge function public key encryption
2015/12/31
OAEP and other similar schemes proven secure in Random-Oracle Model require one or
more hash functions with output size larger than those of standard hash functions. In this
paper, we show that by u...
