A digital signature with multiple subliminal channels and its applications
نویسندگان
چکیده
In this paper, we present two schemes for embedding multiple subliminal messages into one-time signature schemes (OTSSs) proposed by Lamport (1971, 1981) [35,36]. Our schemes have the advantage that the subliminal receivers cannot forge a valid signature since they do not share the signer’s secret key. Our schemes can also providemore than one independent subliminal message, and the numbers of subliminal messages and receivers are larger than that of the subliminal messages in previous schemes. © 2010 Elsevier Ltd.

Digital signature with a subliminal channel - Computers and Digital Techniques, IEE Proceedings-
A subliminal channel is a covert communication chsnnel to send a message to an authorised receiver; this message cannot be discovered by any unauthorised receiver. There are some applications that can take advantage of this by hiding secr1:t messages in this subliminal channel. For example, a credit card provider can hide the card holder’s credit history and credit limit in a digital signature ...

متن کاملExploring Signature Schemes with Subliminal Channel
The subliminal channel in a cryptographic protocol such as an authentication system or a signature scheme provides an additional channel from the sender to an authorized receiver and can’t be read by any unauthorized receiver. In this paper, we firstly show that Hess’s ID-Based signature scheme in SAC’02 can provide digital signature with the broadband and narrowband subliminal channels. Second...

The prisoners’ problem, introduced by Simmons in 1983, describes how two individuals attempt to communicate covertly by exploiting subliminal channels without alerting a ”warden” who controls the communication. Via subliminal channels it is possible to transmit covert messages by embedding them into cryptographic digital data (traditionally by exploiting randomness that is used in probabilistic...
متن کاملA Subliminal Channel in EdDSA:
Subliminal channels in digital signatures provide a very effective method to clandestinely leak information from inside a system to a third party outside. Information can be hidden in signature parameters in a way that both, network operators and legitimate receivers, would not notice any suspicious traces. Subliminal channels have previously been discovered in other signatures, such as ElGamal...
