A method for loading an information-processing resource by a device having a processor and a random-access memory having the steps of: obtaining at least one address corresponding to at least one block of data within which the resource is at least partially recorded; and for said at least one previously obtained current address: loading a current block of data as a function of said current address; obtaining at least one reference certificate of the current block of data; obtaining at least one current certificate of the current block of data, said reference and current certificates being encrypted digital signatures of said current data block; issuing an assertion of validity as a function of said reference and current certificates when said reference and current certificates are identical; copying said current data block into the random-access memory, when said assertion of validity is positive.
