Abstract:
Wireless sensor networks are often more vulnerable than wired ones. Especially, an adversary can attack the
networks by utilizing false route information. A countermeasure against the attack is a secure routing protocol
with digital signatures to guarantee the validity of route information. However, existing secure routing protocols
are inefficient because the memory size and the computational overhead are heavy. To overcome these
problems, we focus on ID-based sequential aggregate signatures (IBSAS) (Boldyreva et al., 2007). IBSAS
allow users to aggregate individual signatures into a single signature. Moreover, certificates of public keys are
unnecessary for IBSAS. Therefore, IBSAS can drastically decrease the memory size and the computational
overhead. Besides, one of the main concerns for practical use is to construct a protocol specification with
IBSAS. Moreover, since IBSAS are sometimes weak against compromising secret keys, another concern is to
construct its countermeasure. F
or these purposes, we propose a secure dynamic source routing with ID-based
sequential aggregate signatures, called ISDSR for short and discuss the key management to revoke/update
compromised keys. We also show that the performance of ISDSR is the best in comparison with the existing
protocols.
