Claims

1. A method for enabling authentication of transport missions, performed in a control device (100, 200, 300) of a member of a group comprising a plurality of autonomous vehicles and an off-board system, wherein each member in the group comprises a cryptographic function known by all other members, the method comprising:

signing (S1 1 ), using the cryptographic function, information defining at least one transport mission to be performed by at least one of the

autonomous vehicles in the group; and

sending (S12) the signed information to a plurality of the other members of the group, in order to request them to authenticate the transport mission.

2. The method according to claim 1 , comprising storing (S14) the signed

information in the member.

3. The method according to claim 2, wherein the storing (S14) comprises storing the signed information in a block chain, in response to receiving (S13) an authentication of the transport mission from at least a predefined number of the other members of the group.

4. The method according to any one of the preceding claims, wherein the signing (S1 1 ) comprises generating a signature, using the cryptographic function, based on information defining the mission to be performed and on information associated with previously authenticated missions performed by the

autonomous vehicles in the group.

5. The method according to any one of the preceding claims, wherein the signing (S1 1 ) comprises creating a block comprising information defining the mission to be performed, using the cryptographic function, for use in a block-chain, and wherein the sending (S12) comprises sending the signed information including the block to the plurality of members in the group.

6. A computer program comprising instructions which, when the program is

executed by a control device, cause the control device to carry out the method of any one of the preceding claims.

7. A computer-readable storage medium comprising instructions which, when executed by a control device, cause the control device to carry out the method of any one of the claims 1 to 5.

8. A control device (100, 200, 300), for enabling authentication of transport

missions, where the control device (100, 200, 300) is a control device (100, 200, 300) of a member of a group comprising a plurality of autonomous vehicles and an off-board system, wherein each member in the group comprises a cryptographic function known by all other members, wherein the control device (100, 200, 300) is configured to perform the method according to any of the claims 1 to 5.

9. A method for authenticating transport missions, performed by a control device (100, 200, 300) of a member of a group comprising a plurality of autonomous vehicles and an off-board system, wherein each member in the group comprises a cryptographic function known by all other members, wherein the method comprises:

receiving (S21 ), from a member in the group, signed information defining at least one transport mission to be performed by at least one of the autonomous vehicles in the group;

verifying (S22) the authenticity of the transport mission, using the cryptographic function.

10. The method according to claim 9, further comprising sending (S23) an authentication of the transport mission to the at least one autonomous vehicle, in response to the mission being verified as authentic.

1 1. The method according to claim 9 or 10, comprising sending (S24) an

authentication of the transport mission to a plurality of the members in the group, in response to the mission being verified as authentic.

12. The method according to claim 9, wherein the control device (200, 300) is arranged in the at least one autonomous vehicle, and the method comprises:

authorizing (S25) the at least one autonomous vehicle to execute the transport mission, in response to receiving an authentication of the transport mission from at least a predefined number of the other members of the group.

13. The method according to claim 12, wherein the method comprises:

sending (S26), to the off-board system, an acknowledgment of the authorization to execute the transport mission by the at least one autonomous vehicle.

14. The method according to any of the claims 9 to 13, comprising

storing (S27) the signed information in the control device (100, 200, 300), in response to receiving an authentication of the transport mission from at least a predefined number of the other members of the group.

15. The method according to claim 14, wherein the storing (S27) comprises

adding the signed information to a block chain in the control device (100, 200, 300).

16. The method according to any of the claims 9 to 15, comprising

determining (S28) that the at least one transport mission is not authentic, in response to a pre-determined time expiring before receiving an authentication from at least a predefined number of the other members of the group.

17. A computer program comprising instructions which, when the program is

executed by a control device, cause the control device to carry out the method of any one of the claims 9 to 16.

18. A computer-readable storage medium comprising instructions which, when executed by a control device, cause the control device to carry out the method of any one of the claims 9 to 16.

19. A control device (100, 200, 300), for authenticating transport missions, where the control device (100, 200, 300) is a control device (100, 200, 300) of a member of a group comprising a plurality of autonomous vehicles and an off- board system, wherein each member in the group comprises a cryptographic function known by all other members, wherein the control device (100, 200, 300) is configured to perform the method according to any one of the claims 9 to 16.

20. An autonomous vehicle (1 ) comprising a control device (100, 200, 300)

according to claim 8, and/or a control device (100, 200, 300) according to claim 19.
