Idea: use a sufficiently-long random ID
- A server allocates a sufficiently-long ID (say
2^128bits) as a handle.- Brute force attack on a large space is inevitable: even if each attempt can finish in 1 nanosecond, trying 2^128 take far longer than the age of the universe.
- Clients simply use or share the allocated ID to use the resource.
Pros
- We don't need to implement anything in kernel.
Cons
- We can't move the handle ownership: every tasks that know the handle ID can use the handle.

Idea: encrypted handle
- IIRC, this idea is inspired by a IPC mechanism in a L4 microkernel implementation.
- A server encrypts a 32/64-bits long value (like a user pointer to the server's control block for the handle) using server's private key.
- Encrypted value is used as the handle. Clients can use or share the handle by simply copying it.
Pros
- Like JWT, the handle is self-contained: the server don't have to manage a table to manage handles.
Cons
- We can't move the handle ownership: every tasks that know the handle ID can use the handle.
