Übersetzung für "Cold boot" in Deutsch

If yes, this indicates a cold-boot attack.

If yes, this also indicates a cold-boot attack.

If at least two indicators indicate a cold-boot attack, the random access memory is cleared.

In a state 104, the software is restarted according to a cold boot.

In a state 112, the cold boot is carried out.

The start of the software during the first time period T 1 is the cold boot.

The cold boot comprises a hardware integrity test and/or a software update check.

A cold boot was around 30 seconds with a wireless keyboard and mouse connected.

I would burn it to the ground until the last ember went cold beneath my boot.

The invention relates to a method for defending against cold-boot attacks on a computer in a self-service terminal.

At the worst, you must do a cold boot with the result of a total data loss.

They raise us like children. And eventually, they take a cold, hard boot, And they kick us out of the nest.

If tab loading times are what really irk you, factor in tab loading times more so than memory usage or cold boot time when picking which browser fits your speed needs.

Chrome, for the first time in a long time, leaped into first place, no doubt due to its new pre-rendering feature and always-awesome JavaScript tests (not to mention a slight win in cold boot times).

This is advantageous, since the housing is opened during many cold-boot attacks in order to freeze the memory by means of cold spray.

Thus, by using sensors which are already available which indicate the opening of the housing or the temperature of the processor, it is possible to detect and repel a cold-boot attack in a highly economical and reliable manner.

US 2012/0 079 593 A1 describes a system and a method for hindering cold-boot attacks, which focuses on mobile terminals such as mobile telephones or laptops.

To defend against cold-boot attacks, it is described there (see text [0009] and claim 3) to monitor the temperature of the memory components and to check whether the temperature is below a threshold value, in order to determine whether or not an attack is taking place.

The object of the present invention is to provide a method for defending against cold-boot attacks which may be used in the field of self-service terminals and which overcomes the initially specified disadvantages of the prior art.

In particular, cold-boot attacks are to be effectively and reliably repelled on computers in self-service terminals without having to accept a noticeable delay of all restarts.

Accordingly, a method is provided for defending against cold-boot attacks on a computer in a self-service terminal which includes the following steps, which are carried out by means of the main processor and a system software program configured for the system startup of the computer, in particular BIOS or (U)EFI:

The method may in particular be used at self-service terminals which are the target of potential cold-boot attacks, such as ATM machines.

It is to be noted that ‘second state data’ concerns the temperature of the processor, which may be ascertained very simply, since modern motherboards have corresponding temperature sensors, and a substantial reduction of the temperature of the processor may also be an indication of a cold-boot attack.

In this respect, the inventor assumes the knowledge that in many cold-boot attacks, spraying the main memory with cold spray also causes the operating temperature of the processor to be decreased.

However, if it is detected in step 212 that the processor temperature T is not less than TK, this does not indicate a cold-boot attack.

However, another criterion is subsequently checked in at least one additional step in order to check additional indicators of a possible cold-boot attack.

If this is the case, then this indicates a cold-boot attack, and step 220 may be initiated to clear the random access memory.

If this is the case, then this is an indicator of a cold-boot attack, and step 220 may be initiated for clearing the random access memory.
