Abstract: Methods, apparati, and computer-readable media for securely transporting a software application onto a tamper resistant module (TRM) (103) by using an individualized TRM key set. A method embodiment of the present invention comprises: storing a key pair unique to the TRM (103) in a memory located on the TRM (103), where the key pair comprises a TRM public key (150) and a TRM private key (190); retrieving the TRM public key from the TRM; encrypting a portion of the software application using the TRM public key (150); transmitting the encrypted software application to the TRM (103); and recovering and decrypting the encrypted software application using the TRM private key(190).

Abstract: Methods and apparati for securely loading one or more computer software applications onto a tamper resistant module (TRM) (107) and for securely deleting one or more applications from the TRM. An embodiment of the invention comprises a method for determining, based at least upon an encrypted personalization data block, whether a TRM (107) is part of a qualified set of TRM's to accept loading of an application. Thereafter, the method provides for loading the application onto the TRM (107) only after the first step determines that the TRM (107) is qualified to accept the loading of the application. Another embodiment comprises a method for determining, based at least upon an encrypted personalization data block, whether a TRM (107) is part of a qualified set of TRM's to accept deleting of an application. Thereafter, the method provides for deleting the application from the TRM (107) only when the first step determines that the TRM (107) is qualified to accept the deleting of the application.

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.
