—A new attack (called " gradient statistical ") on block ciphers is suggested and experimentally investigated. We demonstrate the possibility of applying it to ciphers for which no attacks are known except for the exhaustive key search.
Mathematical simulation of the time course of p53 and Mdm2 protein concentrations during their interactions was carried out. The system states corresponding to threatened uncontrolled apoptotic cell death accelerating aging processes and to situation with hypersuppression of p53-dependent apoptosis fraught with high risk of cancer were modeled. New data… (More)
Digital simulation of disorders in the p53 and Mdm2 protein system, involved in repair of DNA defects and in many vital processes, including tumor formation, neurodegeneration, and aging, was carried out on the base of functional nonlinear octoparametric mathematical model. Stress situations were studied, associated with emergence of imbalance in p53 and… (More)
