Recent studies have demonstrated that it is possible to perform public key cryptographic operations on the resource-constrained sensor platforms. However, the significant resource consumption imposed by public key cryptographic operations makes such mechanisms easy targets of Denial- of Service (DoS) attacks. For example, if digital signatures such as ECDSA are used directly for broadcast authentication without further protection, an attacker can simply broadcast forged packets and force the… CONTINUE READING
