Abstract

This work presents parametric versions of symmetric cryptic algorithms that emphasises on generation and usage\nof key based on parameter only. The key construction process has been extended for generation of alphanumeric keys apart\nfrom numeric one with exploiting domain of parameter selection from personnel information logs. The hypothesis of\nparametric but variable key for cryptic model (usable for Automatic Variable Key) tested with the freedom of user for the\nparameter selection and variation in the parameters according to comfort instead of using series, recurrence relation or\nlocation information [8, 21]. The paper investigates parametric model in the light of Association Rule Mining for such\ncryptosystem [15]. Useful inferences and results from testing results helps in auditing of AVK based cryptic algorithm and\nidentifies power of using a large number of parameters for secure information exchange.
