Abstract

Claims (37)

1 . A method comprising:

tokenizing, by a subscription maker, source code comprising an implementation of an operating system of a Secondary Platform and applications of the Secondary Platform to produce tokenized source code;

tokenizing and filling, by the subscription maker, personalization data associated with a subscription of a user of a Smart Secure Platform (SSP) supporting a Primary Platform and the Secondary Platform to produce tokenized personalization data;

generating, by the subscription maker, an interoperable Secondary Platform Bundle (SPB) in accordance with the tokenized source code and the tokenized personalization data, the interoperable Secondary Platform Bundle meeting an interoperability scheme for the Secondary Platform and the Primary Platform;

delivering, by the subscription maker, the interoperable Secondary Platform Bundle; and

ciphering the interoperable Secondary Platform Bundle and saving the ciphered Secondary Platform Bundle in a memory or server.

2 . The method of claim 1 , further comprising generating, by the subscription maker, the source code.

3 . The method of claim 1 , the interoperable Secondary Platform Bundle being delivered to a Secondary Platform Bundle Manager.

4 . The method of claim 1 , wherein the Primary Platform and the interoperable Secondary Platform Bundle are non-interoperable.

5 . The method of claim 1 , wherein tokenizing the source code comprises substituting keywords of the source code with tokens or bytecode.

6 . A method comprising:

compiling, by a compiler of a Smart Secure Platform (SSP) supporting a Primary Platform and a Secondary Platform, source code to produce compiled source code compatible with an operating system of the Primary Platform, the source code comprising an implementation of an operating system of the Secondary Platform and applications of the Secondary Platform;

linking, by the compiler, personalization data to the compiled source code to produce a native Secondary Platform Bundle (SPB) compatible with the Primary Platform, the personalization data associated with a subscription of a user of the Smart Secure Platform, wherein producing the native Secondary Platform Bundle comprises:

storing a ciphered Secondary Platform Bundle in a memory or a server; and

deciphering the ciphered Secondary Platform Bndle after retrieving it from the memory or the server; and

delivering, by the compiler, the native Secondary Platform Bundle.

7 . The method of claim 6 , further comprising receiving, by the compiler, an interoperable Secondary Platform Bundle comprising the source code and the personalization data.

8 . The method of claim 6 , wherein the operating system of the Secondary Platform and the operating system of the Primary Platform are non-interoperable.

9 . The method of claim 6 , wherein the compiler includes an on-module compiler, wherein the on-module compiler is implemented in an SPB Loader (SPBL) of the Smart Secure Platform.

10 . The method of claim 6 , wherein the personalization data includes tokenized and filled personalization data of the subscription of the user.

11 . The method of claim 6 , wherein the source code and the personalization data meet an interoperability scheme.

12 . The method of claim 6 , wherein keywords of the source code are substituted with tokens or bytecode.

13 . A Smart Secure Platform (SSP) supporting a Primary Platform and a Secondary Platform, the Smart Secure Platform comprising:

one or more processors; and

a non-transitory memory storage coupled to the one or more processors, the non-transitory memory storage comprising instructions that, when executed by the one or more processors, cause the Smart Secure Platform to:

compile source code to produce compiled source code compatible with an operating system of the Primary Platform, the source code being tokenized, the source code comprising an implementation of an operating system of the Secondary Platform and applications of the Secondary Platform;

link personalization data to the compiled source code to produce a native Secondary Platform Bundle (SPB) compatible with the Primary Platform, the personalization data associated with a subscription of a user of the Smart Secure Platform, wherein producing the native Secondary Platform Bundle comprises:

storing a ciphered Secondary Platform Bundle in a memory or a server, and

deciphering the ciphered Secondary Platform Bundle after retrieving it from the memory or the server; and

deliver the native Secondary Platform Bundle.

14 . The Smart Secure Platform of claim 13 , wherein the instructions, when executed by the one or more processors, cause the Smart Secure Platform to receive an interoperable Secondary Platform Bundle comprising the source code and the personalization data.

15 . The Smart Secure Platform of claim 13 , wherein the operating system of the Secondary Platform and the operating system of the Primary Platform are non-interoperable.

16 . The Smart Secure Platform of claim 13 , wherein the personalization data includes tokenized and filled personalization data of the subscription of the user.

17 . The Smart Secure Platform of claim 16 , wherein the source code and the personalization data are combined by concatenation.

18 . The Smart Secure Platform of claim 13 , wherein the source code and the personalization data meet an interoperability scheme.

19 . The Smart Secure Platform of claim 13 , further comprising an on-module compiler, implemented in an SPB Loader (SPBL) of the Smart Secure Platform.

20 . The Smart Secure Platform of claim 13 , further comprising a power management circuit configured to control power consumption of the Smart Secure Platform.
