| Abstract(in English) | With a rapid increase in the number of IoT devices, manyidentity-based authenticated key exchange (IBAKE) protocols for themhas been proposed. Iwai~et~al. proposed an IoT-eCK secure IBAKEprotocol at SCIS2019. This report modifies the protocol, where thestatic secret keys of each entity includes a part of master publickeys in the underlying protocol, and examines its id-eCK security. Inaddition, we discuss that the modified protocol is vulnerable againsta malicious private key generator that holds a value used ingenerating the master keys. |
