Queue management and load shedding for complex authentication schemes

Abstract:

Adjustments to be made to a system for authenticating users may be made by performing the following operations: obtaining a stochastic model of the system, wherein the stochastic model includes two or more classes of requests; obtaining a set of preferences for handling authentication requests and a set of operational parameter values; determining, based at least in part on the stochastic model and the set of operational parameter values, that adjusting an authentication scheme will improve a probable degree to which the authentication system will meet the set of preferences; responsive to the determination that adjusting the authentication scheme will improve the probable degree to which the system for authenticating users will meet the set of preferences, adjusting the authentication scheme of the system for authenticating users; and performing an authentication of a user based on the adjusted authentication scheme.
