Features of the formation of TEMPEST in a computer keyboard from the point of view of ensuring information security



The paper analyzes the possibilities of the formation of spurious electro­magnetic radiation and interference in computer keyboards with the ps/2 in­terface, which can lead to information leaks. The dependences of the physical parameters of the PEMIN on the design features of the equipment used are es­tablished. Possible channels of unauthorized information retrieval, through the use of TEMPEST, are analyzed. Recommendations for the safe use of ps/2 keyboards in information systems are formed.
