Abstract
The present disclosure relates to a device for supporting Input/Output (I/O) channel protection. The device maintains one or more channel protection enclaves (CPEs), wherein each CPE is associated with a different I/O channel, wherein each I/O channel is associated with a different address space of a memory, and wherein each CPE is allocated verification information comprising the address space associated with its associated I/O channel. The device further receives a transaction on a given I/O channel, the transaction comprising access information including one or more target addresses. Moreover, the device determines a correlation of the transaction's access information and the verification information of the CPE associated with the given I/O channel, and allows or aborts execution of the transaction, based on whether the determined correlation meets a predefined criterion.
