Hi, 

I am a beginner in SGX, I want to make a system of several enclaves forming a ring. For communication between two enclaves, I want to know if it is possible to make Asynchronous ECALL from one enclave to another?

Thanks !

Hi,

You cannot make an ECall between enclaves at all. The definition of an ECall is a function call that comes from the untrusted part into the enclave.
