Abstract

An approach is provided for providing identity based encryption in distributed computations. An identity based encryption platform causes, at least in part, a segmentation of a computation closure into at least a first part and one or more second parts. The identity based encryption platform also causes, at least in part, an encryption of the one or more second parts using the first part as a public key of an identity-based encryption.

Claims

1. A method comprising:

segmenting a computation closure into at least a first part and one or more second parts; and

encrypting one or more second parts using the first part as a public key of an identity-based encryption.

2. A method of claim 1, further comprising:

determining (a) one or more criteria for executing the computation closure, the one or more second parts, or a combination thereof;

(b) one or more processes for determining the one or more criteria;

or (c) a combination thereof; and

causing, at least in part, an inclusion of the one or more criteria, the one or more processes, or a combination in the first part.

3. A method of claim 2, further comprising:

causing, at least in part, a publication of the first part, the encrypted one or more second parts, or a combination for access by one or more subscribing devices.

4. A method of claim 3, further comprising:

determining capability information of the one or more subscribing devices; and

processing the capability information associated with the one or more subscribing devices to determine whether the one or more subscribing devices are capable of decrypting the one or more encrypted second parts for execution.

5. A method of claim 4, wherein the capability information is based, at least in part, on energy consumption information, security enforcement information, one or more privacy policies, computational resource information, bandwidth availability information, or a combination thereof.

6. A method according to claim 1, further comprising:

determining one or more anonymization policies associated with the identity-based encryption, the computation closure, the first part, the one or more second parts, or a combination thereof,

wherein the encryption is based, at least in part, on the one or more anonymization policies.

7. A method of claim 6, wherein the one or more subscribing devices include, at least in part, one or more components of one or more levels of a computational architecture.

8. A method of claim 7, further comprising:

determining the one or more anonymization policies based, at least in part, on a concatenation of the one or more level-specific anonymization policies associated with the one or more levels of the computational architecture.

9. A method according to claim 1, wherein the segmentation, the encryption, or a combination thereof of the computation closure is based, at least in part, on one or more cost functions, one or more functional flow maps, or a combination thereof associated with the computation closure.

10. A method according to claim 1, wherein encryption of the one or more second parts is further based, at least in part, on one or more private keys.

22. A computer program product including a computer-readable storage medium and one or more sequences of one or more instructions stored by the computer-readable storage medium, wherein the one or more instructions, when executed by one or more processors, cause an apparatus to at least perform the method of claim 1.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

segmenting a computation closure into at least a first part and one or more second parts; and

encrypting the one or more second parts using the first part as a public key of an identity-based encryption.

12. An apparatus of claim 11, wherein the apparatus is further caused to:

determine (a) one or more criteria for executing the computation closure, the one or more second parts, or a combination thereof;

(b) one or more processes for determining the one or more criteria;

or (c) a combination thereof; and

cause, at least in part, an inclusion of the one or more criteria, the one or more processes, or a combination in the first part.

13. An apparatus of claim 12, wherein the apparatus is further caused to:

cause, at least in part, a publication of the first part, the encrypted one or more second parts, or a combination for access by one or more subscribing devices.

14. An apparatus of claim 13, wherein the apparatus is further caused to:

process capability information associated with the one or more subscribing devices to determine whether the one or more subscribing devices can decrypt the one or more encrypted second parts for execution.

15. An apparatus of claim 14, wherein the capability information is based, at least in part, on energy consumption information, security enforcement information, one or more privacy policies, computational resource information, bandwidth availability information, or a combination thereof.

16. An apparatus according to claim 11, wherein the apparatus is further caused to:

determine one or more anonymization policies associated with the identity-based encryption, the computation closure, the first part, the one or more second parts, or a combination thereof,

wherein the encryption is based, at least in part, on the one or more anonymization policies.

17. An apparatus of claim 16, wherein the one or more subscribing devices include, at least in part, one or more components of one or more levels of a computational architecture.

18. An apparatus of claim 17, wherein the apparatus is further caused to:

21. An apparatus according to claim 11, wherein the apparatus is a mobile phone further comprising:

user interface circuitry and user interface software configured to facilitate user control of at least some functions of the mobile phone through use of a display and configured to respond to user input; and

a display and display circuitry configured to display at least a portion of a user interface of the mobile phone, the display and display circuitry configured to facilitate user control of at least some functions of the mobile phone.
