This invention relates to systems for enhancing the security and authentication algorithms, providing stabilised encryption and stabilised comparing important values, wherein: the security key (symmetrical or asymmetrical) is extended with an additional correction parameter and the security function that uses the key is stimulated to use this parameter for additional operations; the important value for comparison is extended with additional correction parameter, and the comparison of that important value with outside value is stimulated to use the parameter for additional operations. The additional correction parameter consists of two parts - a constant part related to the security key or to the important value for comparison, and a variable part dynamically calculated during the stabilised algorithm being a result of a security function of a transaction state value representative of previous communications. |
