The i-Chip as One-Time Password (OTP) & digital signature generator

Slawomir Matelski

Abstract

For safe resource management - an effective mechanism/system is necessary that identifies a person and his rights to these resources, using an appropriate key, and its degree of security determines not only the property, but sometimes even the life of its owner. For several decades, it has been based on the security of (bio)material keys, which only guarantee their own authenticity, but not their owner, due to weak of static password protection. The development of an effective SecHCI (Secure Human-Computer Identification) system is becoming an increasingly urgent problem in modern civilization. In the article will be presented an innovative challenge-response protocol, that requires only 1 image to be remember by an user, showing the structure of a virtual microchip, and a mental simulation of the operation of its components, thanks to which reverse engineering of the virtual structure is as difficult as such operation on a physical microchip, and their diversity is limited only by the fantasy of the user, inspired by the analogous features of the physical elements. It will be shown how the i-Chip generates the one-time password (OTP) or whole digital signature, also offline on paper documents, or acts as a virtual key for an electronic lock opened with OTP.
