Claim 5:
6. The processing apparatus according to claim 3, wherein the transmission request comprises to-be-transmitted data amount information, and before the storage access controller transmits the specified data stored in the source enclave to the target enclave, the control program sends an allocation request to the target enclave, and
wherein the allocation request comprises the to-be-transmitted data amount information, so that the target enclave determines whether a size of an assignable storage space in the target enclave is greater than or equal to the to-be-transmitted data amount information indicated by the allocation request, and when the size of the assignable storage space in the target enclave is greater than or equal to the to-be-transmitted data amount information indicated by the allocation request, the target enclave sends a transmission acknowledgement response to the storage access controller, so that the storage access controller transmits the specified data stored in the source enclave to the target enclave.
