Analysis and design of key agreement/exchange algorithm with a special emphasis on resource constrained devices has been another area of research at C-MMACS.  Some of the noteworthy works carried out in this regard are key agreement using parameter estimation of chaotic models and use of tree parity model for neural key synchronization. Securing computerized chaotic synchronization process by non-periodic sampling, mutual synchronization, super positioned feedback etc. are some of the other works carried out in this direction. In addition, efforts are also going on to design word based stream ciphers that will be suitable for resource constrained devices.
