Abstract

It is inter alia disclosed to provide first identity data stored in an apparatus, the first identity data comprising an identifier and a first certificate, and to provide second identity data stored in the apparatus, the second identity data comprising an identifier and a second certificate, wherein the identifier of the first identity data is the same as the identifier of the second identity data.

First claim

The invention claimed is:

1. An apparatus, comprising:
at least one processor;
at least one memory including computer program code for one or more programs,
the at least one memory including
first identity data including a first identifier and a first certificate, wherein the first identity data comprises a public key,
second identity data including a second identifier and a second certificate,
wherein the second identity data is associated with an external source associated with utilizing the apparatus to verify a battery pack; and
a communication interface configured to:
facilitate verifying the first identifier is associated with the second identifier, wherein the first identifier is equivalent to the second identifier,
receive an authentication challenge and to provide an authentication response with respect to the authentication challenge based on a private key associated with the public key, and
provide a signature of the authentication challenge obtained by signing the authentication challenge by using the private key associated with the public key, wherein the authentication response comprises the signature.

2. An apparatus according to claim 1 , wherein the first identifier is a unique identifier associated with the battery pack,
wherein the communication interface is further configured to utilize a battery interface standard to facilitate verifying the first identifier and the second identifier are equivalent,
wherein the first identifier is locked with the apparatus,
wherein the apparatus is incorporated into the battery pack.

3. The apparatus according to claim 1 , wherein
the first identifier is part of the first certificate and wherein the second identifier is part of the second certificate.

4. The apparatus according to claim 1 , wherein the first certificate comprises a first signature.

5. The apparatus according to claim 4 , wherein the first signature is signed with a private key, and wherein the second identity data comprises a public key associated with this private key.

6. The apparatus according to claim 1 , wherein the second certificate comprises a second signature.

7. The apparatus according to claim 1 , configured to provide at least one of:
a signature of the first certificate obtained by signing the first certificate by using the private key associated with the public key, and
a signature of the second certificate obtained by signing the second certificate by using the private key associated with the public key.

8. A method performed by an apparatus, including a processor, comprising:
providing first identity data stored in the apparatus, the first identity data including a first identifier and a first certificate, wherein the first identity data comprises a public key;
providing second identity data stored in the apparatus, the second identity data including a second identifier and a second certificate,
wherein the second identity data is associated with an external source associated with utilizing the apparatus to verify a battery pack;
verifying, utilizing the processor, the first identifier is equivalent to the second identifier via a communication interface configured to verify the first identifier is associated with the second identifier,
wherein the first identifier is equivalent to the second identifier;
receiving an authentication challenge including challenge data and providing an authentication response to the authentication challenge based on the verification;
receive an authentication challenge and to provide an authentication response with respect to the authentication challenge based on a private key associated with the public key, and
provide a signature of the authentication challenge obtained by signing the authentication challenge by using the private key associated with the public key, wherein the authentication response comprises the signature.

9. The method according to claim 8 , wherein the first identifier is a unique identifier associated with the battery pack,
wherein the communication interface is further configured to utilize a battery interface standard to facilitate verifying the first identifier and the second identifier are equivalent,
wherein the first identifier is locked in the apparatus,
wherein the apparatus is incorporated into the battery pack.

10. The method according to claim 8 , wherein said providing the first identity data comprises transmitting the first identity data to a further apparatus and wherein said providing the second identity data comprises transmitting the second identity data to the second apparatus.

11. The method according to claim 8 , wherein the first identifier is part of the first certificate and wherein the second identifier is part of the second certificate.

12. The method according to claim 8 , wherein the first certificate comprises a first signature.

13. The method according to claim 8 , wherein the first signature is signed with a private key, and wherein the second identity data comprises a public key associated with this private key.

14. The method according to claim 8 , wherein the second certificate comprises a second signature.

15. The method according to claim 8 , wherein the first identity data comprises a public key.

16. A computer program product comprising a least one computer readable non-transitory memory medium having program code stored thereon, the program code which when executed by an apparatus, including a processor, cause the apparatus at least to:
process first identity data stored in the apparatus, the first identity data including a first identifier and a first certificate, wherein the first identity data comprises a public key;
process second identity data stored in the apparatus, the second identity data including a second identifier and a second certificate,
wherein the second identity data is associated with an external source associated with utilizing the apparatus;
verify, utilizing the processor, the first identifier is associated with the second identifier via a communication interface configured to facilitate verifying the first identifier is associated with the second identifier,
wherein the first identifier is equivalent to the second identifier;
receive an authentication challenge including challenge data and provide an authentication response to the authentication challenge based on the verification;
receive an authentication challenge and to provide an authentication response with respect to the authentication challenge based on a private key associated with the public key, and
provide a signature of the authentication challenge obtained by signing the authentication challenge by using the private key associated with the public key, wherein the authentication response comprises the signature.

17. A computer program product according to claim 16 , wherein the first identifier is a unique identifier associated with the battery pack,
wherein the communication interface is further configured to utilize a battery interface standard to facilitate verifying the first identifier and the second identifier are equivalent,
wherein the first identifier is locked with the apparatus,
wherein the apparatus is incorporated into the battery pack.
