Abstract: A cross authentication method includes steps of: a host central processing unit (CPU) module sending to a baseboard management controller (BIC) a request for BMC signature; the host CPU module receiving BMC signature data from the BMC; the host CPU module determining whether the received BMC signature data is authentic based on a BMC public key stored in the host CPU module; and the host CPU module allowing the BMC to access the host CPU module when it is determined that the BMC signature data is authentic.
