Method and applet - application machine for processing a computer - applets, as well as a computer software - applet

摘要

A method of processing an applet comprises storing a file in a persistent storage medium (PSM), the file including an access control list 20; transmitting an applet from a server, the applet including at least one of applet identification data and a private key encrypted domain identifier and public key pair, a maximum file size indicator, and a specification of required operations; receiving the applet by an application engine 16; in the event the domain identifier is included in the applet, decrypting the domain identifier using the public key; checking at least one of the applet identification data and decrypted domain identifier against the access control list for a match, and in the event a match is found, allowing the operations specified in the applet on a file stored in a persistent storage medium and as specified in the file access control list.
