Title: Memory management method, memory device, computer system, compiler and program
Inventor: HARIKAWA YORIYUKI
IPC: G06F21/60
Filed: 2002-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a memory management technique for avoiding stack smashing attack.  <P>SOLUTION: When securing a local variable storing area LV for a stack of a subroutine, the size of the local variable storing area LV is determined randomly in a range larger than the required size for storing all local variables declared, in a source program of the subroutine. Thus, because it is impossible to precisely anticipate the relative position of a return address storing area RA, in a stack frame from the source code or the like, it becomes very difficult to rewrite the return address with a destination address (the start address of the malicious program code) by the stack-smashing attack.  <P>COPYRIGHT: (C)2004,JPO

IPC: B60H1/00
Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a heat shock upon getting off while restraining comfortability upon getting on from being impaired to the minimum.  <P>SOLUTION: A required traveling time from the present area to a predetermined area for getting off is presumed and in the case where the required traveling time is within a predetermined time, a heat shock reduction control for air conditioning is carried out such that a temperature Tr in a cabin is brought closer to a temperature Tam of external air. Thereby, since a temperature difference ΔT of the temperature Tr in the cabin and the temperature Tam of external air can be made small at the time of getting off, the reduction of the heat shock upon getting off can be realized. Since the heat shock reduction control is not carried out until the required traveling time gets to within a predetermined time tc, the comfortability of the temperature cannot be impaired until at least the required traveling time gets to within the predetermined time. According to the above, the purpose can be accomplished.  <P>COPYRIGHT: (C)2004,JPO
