The paper examines and analyzes contact identification systems based on the OneWire single-wire protocol (iButton) for possible vulnerabilities, the implementation of iButton key-identifier forgeries, as well as the prospects of using the OneWire interface in modern communication systems and information security systems. The developed experimental sample of the universal identifier device «Touch Memory», made on a programmable chip, makes it possible to fine-tune methods and algorithms for protection against unauthorized access by intruders. Despite all the advantages of systems built on iButton technology, they cannot provide absolute information protection. The proposed software implementation solutions developed in the course of this work can serve as material for improving the keys and algorithms of iButton devices. The solutions proposed in the work allow for two-stage identification with a given branching
