On complete one-way functions
Complete constructions play an important role in theoretical computer science. However, in cryptography complete constructions have so far been either absent or purely theoretical. In 2003, L.A. Levin presented the idea of a combinatorial complete one-way function. In this paper, we present two new one-way functions based on semi-Thue string rewriting systems and a version of the Post correspon...
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 کاملCalreticulin: one protein, one gene, many functions.
The endoplasmic reticulum (ER) plays a critical role in the synthesis and chaperoning of membrane-associated and secreted proteins. The membrane is also an important site of Ca(2+) storage and release. Calreticulin is a unique ER luminal resident protein. The protein affects many cellular functions, both in the ER lumen and outside of the ER environment. In the ER lumen, calreticulin performs t...
متن کاملThe Effect of Visual and Interactive Tools on Students’ Performance in Identifying one-to-one Functions
This paper investigates the effect of using computer applications on students’ capabilities in distinguishing a type of functions. The type of functions is one-to-one and the use of the computer applications was through visual and interactive webbased tools. The students who participated in this study were divided into two groups: control and experimental. The students in the first group were t...
