The first feature is that the Kaspersky OS is based on microkernel architecture, which basically means using the minimum amount of ingredients to bake your own operating system.
The rest of the operating system outside the microkernel will still need to include all the other desired operating system features missing from the microkernel. There are the same "amount of ingredients", they're just mostly implemented outside the kernel.
This isn't requiring encryption, so I don't see what the problem is.
