Chaos Machine: Different Approach to the Application and Significance of Numbers
number theory pseudo-randomness one-way functions
2016/5/18
In this paper we describe a theoretical model of \underline{chaos machine}, which combines the benefits of hash function and pseudo-random function, forming flexible \textit{one-way} \underline{push-p...
Computing on the Edge of Chaos: Structure and Randomness in Encrypted Computation
Cryptography complexity theory homomorphic encryption
2016/1/8
This survey, aimed mainly at mathematicians rather than practitioners, covers recent developments
in homomorphic encryption (computing on encrypted data) and program obfuscation (generating
encrypte...
We construct trapdoor permutations based on (sub-exponential) indistinguishability obfuscation and oneway
functions, thereby providing the first candidate that is not based on the hardness of factori...
The weak password problem: chaos, criticality, and encrypted p-CAPTCHAs
foundations / applications complexity theory foundations key management
2012/3/29
Vulnerabilities related to weak passwords are a pressing global economic and security issue. We report a novel, simple, and effective approach to address the weak password problem. Building upon chaot...
A New Chaos-Based Cryptosystem for Secure Transmitted Images
Chaos-based cryptosystem perturbed technique error propagation
2010/2/1
This paper presents a novel and robust chaos-based cryptosystem for secure transmitted images and four others versions. In the proposed block encryption/decryption algorithms, an 2D chaotic map is use...
