• Sometimes it can be shown mathematically that a cryptosystem is strong (if x can break this system, than x can solve the well-known difficult problem of factoring integers)
â € ¢ Wakati mwingine inaweza kuonyeshwa kupitia hesabu kwamba cryptosystem ni nguvu (kama x unaweza kuvunja mfumo huu, kuliko x wanaweza kutatua maalumu tatizo gumu la factoring integers)
