Abstract
Methods and systems for flexibly loading an application, e.g., a software application, and associated data from an application provider (101) onto a tamper resistant module (TRM) (103) having an I/O buffer (115) and a memory (119). A method embodiment of the invention comprises determining (501) the size of the TRM's I/O buffer (115), segmenting (503) the application to be loaded and its associated data into a plurality of segments, with each segment adapted to be stored in the I/O buffer (115) and the size of each segment being a function of the determined size of the I/O buffer (115), separately transmitting (505) each segment to the tamper resistant module (103), and storing (603) each separately transmitted segment in a selected one of one or more available spaces of the TRM's memory (119), said spaces selected depending upon the size of each segment and upon which of said available spaces has the smallest available area in the TRM's memory (119) in which the segment can be stored.
