2023/11/29
Communication compression is an essential strategy for alleviating communication overhead by reducing the volume of information exchanged between computing nodes in large-scale distributed stochastic ...
Superstructure-Based Simultaneous Optimization of a Heat Exchanger Network and a Compression-Absorption Cascade Refrigeration System for Heat Recovery
Heat Exchanger Network Refrigeration System Heat Recovery
font style='font-size:12px;'>
2023/6/19
A heat exchanger network (HEN) plays an important role in the chemical process industry owing to its significant effect in energy recovery. A compression-absorption cascade refrigeration system (CACRS...
A new elliptic curve point compression method based on Fp-rationality of some generalized Kummer surfaces
elliptic cryptography point compression Barreto-Naehrig curves

2019/9/19
In the article we propose a new compression method (to 2log2(p)+32log2(p)+3 bits) for the Fp2Fp2-points of an elliptic curve Eb:y2=x3+bEb:y2=x3+b (for b∈F∗p2b∈Fp2∗) of jj-invariant ...
On NIST's Compression Estimate Test
IID Non-IID Min Entropy
font style='font-size:12px;'>
2019/8/27
In this paper we present our observations about NIST's Compression estimate test given in SP-800 90B. We observe that steps 4 and 7 of the test may be re-framed to gain efficiency. Based on our observ...
Information Conservational Security with “Black Hole” Keypad Compression and Scalable One-Time Pad — A Quantum Intelligence Approach to Pre- and Post-Quantum Cryptography
Pre- and Post-Quantum Cryptography Scalable One-Time Pad (S-OTP) Information Conservational Security (ICS)
font style='font-size:12px;'>
2019/8/14
Whereas it is widely deemed impossible to overcome the optimality of the one-time pad (OTP) cipher in pre- and post-quantum cryptography, this work shows that the optimality of information theoretic s...
Txilm: Lossy Block Compression with Salted Short Hashing
Blockchain Bitcoin Hash Algorithm
font style='font-size:12px;'>
2019/6/5
Current blockchains are restricted by the low throughput. Aimed at this problem, we propose Txilm, a protocol that compresses the size of transaction presentation in each block and thus saves the band...
Dual Isogenies and Their Application to Public-key Compression for Isogeny-based Cryptography
Post-quantum cryptography public-key compression supersingular elliptic curves
font style='font-size:12px;'>
2019/5/21
The isogeny-based protocols SIDH and SIKE have received much attention for being post-quantum key agreement candidates that retain relatively small keys. A recent line of work has proposed and further...
Output Compression, MPC, and iO for Turing Machines
Randomized encodings compact MPC indistinguishability obfuscation
font style='font-size:12px;'>
2018/11/13
In this work, we study the fascinating notion of output-compressing randomized encodings for Turing Machines, in a shared randomness model. In this model, the encoder and decoder have access to a shar...
Public Key Compression for Constrained Linear Signature Schemes
digital signatures post-quantum quantum random oracle model
font style='font-size:12px;'>
2018/7/16
We formalize the notion of a constrained linear trapdoor as an abstract strategy for the generation of signature schemes, concrete instantiations of which can be found in MQ-based, code-based, and lat...
Weak Compression and (In)security of Rational Proofs of Storage
information theory proofs of storage rational security
font style='font-size:12px;'>
2018/5/28
We point out an implicit unproven assumption underlying the security of rational proofs of storage that is related to a concept we call weak randomized compression.
Revisiting a Masked Lookup-Table Compression Scheme
side-channel attack masking block cipher
font style='font-size:12px;'>
2017/10/25
Lookup-table based side-channel countermeasure is the prime choice for masked S-box software implementations at very low orders. To mask an nn-bit to mm-bit S-box at first- and second- orders, one req...
Compression for trace zero points on twisted Edwards curves
elliptic curve cryptography trace-zero subgroup Edwards curves
font style='font-size:12px;'>
2017/9/18
We propose two optimal representations for the elements of trace zero subgroups of twisted Edwards curves. For both representations, we provide efficient compression and decompression algorithms. The ...
Running compression algorithms in the encrypted domain: a case-study on the homomorphic execution of RLE

font style='font-size:12px;'>
2017/5/11
This paper is devoted to the study of the problem of running compression algorithms in the encrypted domain, using a (somewhat) Fully Homomorphic Encryption (FHE) scheme. We do so with a particular fo...
