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. For 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.
