Breach the Gate: Exploiting Observability for Fault Template Attacks on Block Ciphers
Fault attacks PRESEN
2019/8/19
Fault attacks (FA) are one of the potent practical threats to modern cryptographic implementations. Over the years the FA tech- niques have evolved, gradually moving towards the exploitation of device...
On the Data Limitation of Small-State Stream Ciphers: Correlation Attacks on Fruit-80 and Plantlet
Small-state stream cipher Grain Correlation attack
2019/7/15
Many cryptographers have focused on lightweight cryptography, and a huge number of lightweight block ciphers have been proposed. On the other hand, designing lightweight stream ciphers is a challengin...
Fast Correlation Attacks on Grain-like Small State Stream Ciphers and Cryptanalysis of Plantlet, Fruit-v2 and Fruit-80
Fast correlation attack Stream cipher Grain-like
2019/7/8
The fast correlation attack (FCA) is one of the most important cryptanalytic techniques against LFSR-based stream ciphers. In CRYPTO 2018, Todo et al. found a new property for the FCA and proposed a n...
Generalized Related-Key Rectangle Attacks on Block Ciphers with Linear Key Schedule
Key Recovery Rectangle Attack SKINNY
2019/6/19
This paper gives a new generalized key-recovery model of related-key rectangle attacks on block ciphers with linear key schedules. The model is quite optimized and applicable to various block ciphers ...
On designing secure small-state stream ciphers against time-memory-data tradeoff attacks
Stream cipher Ultra-lightweight Small-state
2019/6/10
A new generation of stream ciphers, small-state stream ciphers (SSCs), was born in 2015 with the introduction of the Sprout cipher. The new generation is based on using key bits not only in the initia...
It has been 70 years since the publication of the seminal outstanding work of Claude Elwood Shannon, in which he first gave a mathematical definition of the cryptosystem and introduced the concept of ...
Transform-and-Encode: A Countermeasure Framework for Statistical Ineffective Fault Attacks on Block Ciphers
Fault Attack Block Cipher Masking
2019/5/23
Right from its introduction by Boneh et al., fault attacks (FA) have been established to be one of the most practical threats to both public key and symmetric key based cryptosystems. Statistical Inef...
The slide attack is a powerful cryptanalytic tool which has the unusual property that it can break iterated block ciphers with a complexity that does not depend on their number of rounds. However, it ...
Lightweight Authenticated Encryption Mode of Operation for Tweakable Block Ciphers
Authenticated encryption beyond-birthday-bound security tweakable block- cipher
2019/4/3
Using a small block length is a common strategy in designing lightweight block cipher. So far, many 64-bit primitives have been proposed. However, if we use such a 64-bit primitive for an authenticate...
Quantum Distinguishing Attacks against Type-1 Generalized Feistel Ciphers
Generalized Feistel cipher Simon's algorithm Grover search,
2019/4/1
A generalized Feistel cipher is one of the methods to construct block ciphers, and it has several variants. Dong, Li, and Wang showed quantum distinguishing attacks against the (2d−1)(2d−1...

2019/3/20
We propose a general method for security evaluation of SNOW 2.0-like ciphers against correlation attacks that are built similarly to known attacks on SNOW 2.0. Unlike previously known methods, the met...
Zero-Correlation Attacks on Tweakable Block Ciphers with Linear Tweakey Expansion
Symmetric-key cryptography tweakable block ciphers zero-correlation
2019/3/1
The design and analysis of dedicated tweakable block ciphers is a quite recent and very active research field that provides an ongoing stream of new insights. For instance, results of Kranz, Leander, ...
Efficient and Secure Multiparty Computation from Fixed-Key Block Ciphers
random permutation mode secure computation
2019/1/26
Many implementations of secure computation use fixed-key AES (modeled as a random permutation); this results in substantial performance benefits due to existing hardware support for~AES and the abilit...
