Improved Constant Storage Self-healing Key Distribution with Revocation in Wireless Sensor Networkis that it requires constant storage of personal keys for each user. In this paper, we show that Dutta’s scheme is insecure against the proposed attack, whereby users can access any other’s secret keys and session keys which they should not know according to Dutta’s scheme. Moreover, we proposed two

Finally, we present Gossamer, a new protocol inspired by the recently published SASI scheme [13], that w

Public Key Authentication with Memory Tokensas moderate memory requirements. Our technique is particularly attractive on platforms where memory is already available, since it can be implemented at practically no cost, without any CPU, and with an extremely simple memory access control mechanism.

Certificate-Based Signatures: New Definitions and a Generic Construction from Certificateless Signathas been extended to certificate-based signatures. To date, several new schemes and security models of certificate-based signatures have been proposed. In this paper, we first introduce a new security model of certificate-based signatures. Our model is not only more elaborated when compared with the

In addition, to avert junk content or spam, subscribers must have source authentication with respect to their broadcasters. The limited memory and computational power of mobile devices, coupled with escalating costs of wireless bandwidth make ef
