Abstract

Computer-implemented systems, methods, and computer-readable media for executing a logic on a computing device and protecting the logic against reverse-engineering include creating a deterministic environment to produce a fixed set of time-varying system states, and interpreting and executing a time map based on the fixed set of time-varying system states, the time map being transformed from the logic based on the fixed set of time-varying system states in a protected, deterministic environment.

1 . A method for executing a logic on a computing device and protecting the logic against reverse-engineering, the method comprising:
 creating a deterministic environment to produce a fixed set of time-varying system states, and   interpreting and executing a time map based on the fixed set of time-varying system states;   wherein the time map was transformed from the logic based on the fixed set of time-varying system states in a protected, deterministic environment.

 one or more processors configured to:
 create a deterministic environment to produce a fixed set of time-varying system states, and 
 interpret and execute a time map based on the fixed set of time-varying system states; 
   wherein the time map was transformed from the logic based on the fixed set of time-varying system states in a protected, deterministic environment.   
     
     
         6 . The computer system of  claim 5 , wherein creating the deterministic environment comprises at least one of disabling interrupts and locking down the system bus. 
     
     
         7 . The computer system of  claim 5 , wherein the fixed set of time-varying system states include values from a performance counter of a processor of the computing device.

 creating a deterministic environment to produce a fixed set of time-varying system states, and   interpreting and executing a time map based on the fixed set of time-varying system states;   wherein the time map was transformed from the logic based on the fixed set of time-varying system states in a protected, deterministic environment.   
     
     
         10 . The computer-readable medium of  claim 9 , wherein creating the deterministic environment comprises at least one of disabling interrupts and locking down the system bus. 
     
     
         11 . The computer-readable medium of  claim 9 , wherein the fixed set of time-varying system states include values from a performance counter of a processor of the computing device. 
     
     
         12 . The computer-readable medium of  claim 11 , wherein creating the deterministic environment comprises at least one of disabling interrupts and locking down the system bus.
