Card Operating Systems (COS)

With Keystone's help, getting access to a card operating system is no longer a 'barrier to entry' for applications developers. We offer COS products that can be used for almost any Smart Card application as an operating system. Keystone can provide an OS that is totally self-sufficient and not dependant on any semiconductor producer - available across all hardware platforms. This means that Keystone can offer it on virtually any microcontroller chip of your choice thanks to a robust on-board hardware abstraction layer. There is also a Java version of the operating system. High Security Standards include DES, 3DES, MD2, RSA and ECC security function libraries. Contact us for more details.
