Methods and Apparatus for Data Security in Mobile Ad Hoc Networks

Systems and techniques for key management in mobile ad hoc networks are described. Pseudonyms are defined for group members of mobile ad hoc networks such that a pseudonym in a message can be deterministically identified with the sending device only by the sending device and the message recipient. Key management for a group is performed by a group manager, and key management may include key renewal and revocation. Key renewal is performed by a group manager, with the group manager using a set of couple pseudonyms, including a couple pseudonym between the manger and each group member. Key renewal employs a renewal key used to encrypt the updated group key, and the group manager updates the group key be transmitting a message to each group member in proximity, with the message being identified using the couple pseudonym of the manager and the group member.
