Cryptanalysis of TFHE-Friendly Cipher FRAST

IACR Transactions on Symmetric Cryptology
FRAST is a TFHE-friendly stream cipher that was published at FSE 2025. The cipher is defined over Z16, and makes extensive use of negacyclic S-boxes over Z16 as they are less costly in TFHE.

Improved FHE Bootstrapping and Its Applications in Discretized Neural Networks

IET Information Security
The inefficiency of bootstrapping is the primary bottleneck preventing fully homomorphic encryption (FHE) from practical applications. One of the main obstacles to improving the bootstrapping performance using hardware acceleration is the large storage ...

Practical TFHE Ciphertext Sanitization for Oblivious Circuit Evaluation [PDF]

Proceedings of the 2025 ACM SIGSAC Conference on Computer and Communications Security
Homomorphic encryption (FHE) enables the computation of arbitrary circuits over encrypted data. A widespread application of HE is oblivious circuit evaluation, where a sender evaluates its private circuit over a receiver\u27s encrypted data, covering ...

Further Improvements in AES Execution over TFHE [PDF]

IACR Communications in Cryptology
Making the most of TFHE advanced capabilities such as programmable or circuit bootstrapping and their generalizations for manipulating data larger than the native plaintext domain of the scheme is a very active line of research. In this context, AES is a particularly interesting benchmark, as an example of a nontrivial algorithm which has eluded ...

An overview of torus fully homomorphic encryption [PDF]

International Journal of Group Theory, 2023
The homomorphic encryption allows us to operate on encrypted data, making any action less vulnerable to hacking. The implementation of a fully homomorphic cryptosystem has long been impracticable. A breakthrough was achieved only in 2009 thanks to Gentry
