Abstract
A method of protecting a secure USB key comprising: a step of obtaining at least one parameter concerning the use of a function that can be executed on said key; a step of detecting at least one blocking condition that depends on said parameter, and where appropriate, a first check step suitable for preventing the execution of said function; a step of detecting at least one determined event independent of said function; and a second check step suitable for authorizing the execution of said first check step only in the event of said determined event being detected, said second check step being active even when said blocking condition is not satisfied.
