Patent ID: 8417976

Claim:
An information processing apparatus being able to communicate with an external device via a network interface device, comprising: a processor; and a memory coupled to the processor, the memory having instructions that, when executed by the processor, perform operations comprising: detecting that a condition for shifting to a power saving mode, in which power consumption is smaller than that in a normal power mode, is satisfied while the information processing apparatus is operated in the normal power mode, wherein the network interface device executes response processing to a packet received from the external device when the information processing apparatus is in the power saving mode; determining a first encrypted algorithm which is executed by the network interface device; and requesting the external device to change a second encrypted algorithm used for a communication between the information processing apparatus and the external device to the first encrypted algorithm when the detecting detects that the condition is satisfied; determining whether the network interface device can execute the second encrypted algorithm, wherein when the network interface device cannot execute the second encrypted algorithm, the requesting requests the external device to change the second encrypted algorithm to the first encrypted algorithm determined, and wherein when the network interface device can execute the second encrypted algorithm, the requesting does not request the external device to change the second encrypted algorithm.
