چکیده

At CANS 2008, Mashatan and Stinson suggested a message recognition protocol for ad hoc pervasive networks. The protocol provides a procedure to resynchronize in case of a (possibly adversarial) disruption of communication. We show that this resynchronization process does not provide the functionality intended and in fact enables an adversary to create selective forgeries. The computational effort for the attack is negligible and allows the insertion of arbitrary messages.

A New Message Recognition Protocol with Self-recoverability for Ad Hoc Pervasive Networks

We examine the problem of message recognition by reviewing the definitions and the security model in the literature. In particular, we examine the Jane Doe protocol, which was proposed by Lucks et al., more closely and note its inability to recover in case of a certain adversarial disruption. Our paper saves this well-studied protocol from its unrecoverable state when such adversarial disruptio...

On message recognition protocols: recoverability and explicit confirmation

We look at message recognition protocols (MRPs) and prove that there is a oneto-one correspondence between stateless non-interactive MRPs and digital signature schemes. Next, we examine the Jane Doe protocol and note its inability to recover in case of a certain adversarial disruption. We propose a variant of this protocol which is equipped with a resynchronization technique that allows users t...

Practical unconditionally secure two-channel message authentication

We investigate unconditional security for message authentication protocols that are designed using two-channel cryptography. We look at both noninteractive message authentication protocols (NIMAPs) and interactive message authentication protocols (IMAPs). We provide a new proof of nonexistence of nontrivial unconditionally secure NIMAPs. This proof consists of a combinatorial counting argument ...

A New Message Recognition Protocol for Ad Hoc Pervasive Networks

We propose a message recognition protocol which is suitable for ad hoc pervasive networks without the use of hash chains. Hence, we no longer require the devices to save values of a hash chain in their memories. This relaxes the memory requirements. Moreover, we do not need to fix the total number of times the protocol can be executed which implies a desired flexibility in this regard. Furtherm...

Recognition in Ad Hoc Pervasive Networks

We examine the problem of message and entity recognition in the context of ad hoc networks. We review the definitions and the security model described in the literature and examine previous recognition protocols described in [1], [2], [3], [7], and [8]. We prove that there is a one to one correspondence between non-interactive message recognition protocols and digital signature schemes. Hence, ...
