Method of Anti-Virus Protection Based on $(n,t)$ Threshold Proxy Signature with an Arbitrator

The article suggests the method of anti-virus protection of mobile devices based on the usage of proxy digital signatures and an $(n;t)$-threshold proxy signature scheme with an arbitrator. The unique feature of the suggested method is in the absence of necessity to install anti-virus software in a mobile device. It will be enough only to have the software verifying digital signatures and the Internet. The method is used on the base of public keys infrastructure /PKI/, thus minimizing implementation expenses.
