Physical one-way functions.
Modern cryptographic practice rests on the use of one-way functions, which are easy to evaluate but difficult to invert. Unfortunately, commonly used one-way functions are either based on unproven conjectures or have known vulnerabilities. We show that instead of relying on number theory, the mesoscopic physics of coherent transport through a disordered medium can be used to allocate and authen...

متن کاملBiological One-way Functions
Biology has been a rich source of inspiration for computer security professionals. The central dogma of biology contains intronization cipher and substitution cipher with three many-to-one mappings. In cryptography, substitution cipher has been used long before human identifies DNA. However, it seems that no enough attention has been paid to the intronization cipher because it alone does not ma...
متن کاملOne-Time Trapdoor One-Way Functions
Trapdoors are widely used in cryptography, in particular for digital signatures and public key encryption. In these classical applications, it is highly desirable that trapdoors remain secret even after their use. In this paper, we consider positive applications of trapdoors that do not remain secret when they are used. We introduce and formally define one-time trapdoor one-way functions (OTTOW...
متن کاملExtractable Perfectly One-Way Functions
We propose a new cryptographic primitive, called extractable perfectly one-way (EPOW) functions. Like perfectly one-way (POW) functions, EPOW functions are probabilistic functions that reveal no information about their input, other than the ability to verify guesses. In addition, an EPOW function, f , guarantees that any party that manages to compute a value in the range of f “knows” a correspo...
