AI Technical Summary
Existing virtual machine architectures with multiple instances of Linux or Linux-Android operating systems face inefficiencies due to memory waste from loading the same Executable Load File (ELF) multiple times across Logical Secure Elements (LSEs), leading to a high memory footprint and lack of clear division of roles between entities responsible for loading, updating, and deleting ELF content.
A virtual machine architecture with an administrative Logical Secure Element configured to perform administrative commands, including extradition, upgrade, and deletion of application instances across other LSEs, using a shared Java Card package and unique Security Domain Roots to manage LSEs efficiently, thereby reducing memory footprint.
The solution reduces memory usage by allowing shared ELF management across LSEs, optimizing resource allocation and maintaining low memory footprint while enabling efficient administrative operations.
