StepNexus, a division of Multos International, is responsible for overseeing the key management authority (KMA). Through secure communication with the KMA, issuers request and receive enablement data, as well as load/delete certificates. These components are primary constituents of the MULTOS framework, ensuring the integrity of all applications present on the smartcard.

StepNexus also develops and hosts solutions for those clients wishing to implement secure systems, protecting the most sensitive data. Leveraging the experience garnered in deriving the secure protocols utilized in conjunction with the operation of the KMA, StepNexus offers issuers, payment schemes and service providers an excellent resource on which to base their secure service or product offerings.
