Multi Message Signcryption Based On Chaos With Public Verifiability
Aditya Kumar, Mohd Mohiuddin Ansari · 2013
Abstract: Chaos is one type of complex dynamic behaviour generated by determined nonlinear dynamic systems. Dependency on initial conditions and highly unpredictable nature of chaotic signals lead to novel cryptographic applications. Cryptography and chaos have some common features, the most prominent being sensitivity to parameters ’ and variables ’ changes. This paper focuses on multi-message signcryption schemes based on chaoswith public verifiability. In this paper we purpose two signcryption schemes for single and multiple recipients. The purposed schemes use a chaos based multi-key generator to generate multiple keys for signcryption scheme and are publicly verifiable, highly sensitive to the initial conditions, and provide high security due to its chaotic nature.
