What causes YLOD? Basically it is an overheating problem. The PlayStation 3 gives this error message (YLOD) out when the connection between the motherboard and the graphics process is interrupted. This happens too often encountered by overheating. The contacts between the graphic process and the main board are so affected that a connection can not be produced anymore. However, if certain fuses are defective, then the PlayStation 3 also reports the YLOD.
Other errors such as temperature sensor defective, faulty power supply, etc. are almost impossible. A hard disk crash is excluded, because even with a defective hard drive will boot the PS3.
How does the YLOD manifest itself? One can say that the YLOD occurs whenever the PS3 works. So when playing a Blu-ray disc and in all that takes the graphics to deliver. You are watching a movie or playing a game and all of a sudden the picture is gone. The PS3 will beep 3 times and then the LED flashes red. If they now turn on and again we hear may start again the melody but usually the light turns green and then yellow short (this is hardware the clear sign of YLOD) and then it flashes red again.
There is still a disc in the PS3. What now? If this happens to a 60GB PS3, unfortunately there is no way to get it out again. At least not in the normal way. One would have to disassemble the PlayStation. For the 40GB and 80GB versions there’s a little trick to eject the disc forcibly. At least not in the usual way.
What about the data from my HDD? It is not possible to save the data after the occurrence of YLOD save. This is the built in crypto-chip of the PS3 which ensures that the data is encrypted so they can not be hacked. To contribute, however I recommend you regularly perform a backup.
The PlayStation 3 gets much hotter than in the restive state because it has to give sufficient heat whilst in use and this causes ps3 problems. This creates residual heat, which promotes the YLOD. Make sure there is enough space around the PlayStation to suck in enough air to cool the ps3. If at all possible keep it near a window to get additional cooling. If this is not possible, then you could use a fan pointed directed to the PlayStation
The hardware security modules (HSMs) used by the financial services sector are expensive to acquire, operate and maintain. There are various standards for the level of security provided by HSMs with FIPS 140-2 being the most widely accepted. This standard ranges from level 1 to 4 with 4 being the most secure.
HSMs are widely seen as being superior to their software counterparts as they allow for tamper protection including tamper evidence, resistance, and response. HSMs can be deployed for any application that uses digital encryption keys. These keys are usually of high-value where they protect important and confidential information. Providing secure key storage, full audit and log traces and encryption checks on PIN blocks for transactions are just some of the uses for HSMs.
The main problem with banking HSMs is the interoperability issues surrounding HSM application programming interfaces (APIs) and applications which cause inefficient usage of capacity. For example, one application which may need one HSM also requires an additional one for back up as well as development and testing which also require a minimum of one HSM each. This may result in every application that only requires one HSM for maximum peak time usage actually takes up a minimum of four HSMs with huge additional costs attached to each application. This means that many HSMs are on average only utilized to 25% or less of their capacity.
Proprietary interfaces provided by the HSM vendors is part of the reason to the aforementioned issue by making it almost impossible for applications to be shared across HSMs. These interfaces also make it difficult to integrate new and existing applications resulting in long delays in projects requiring crypto. Once an application is using a certain HSM, many users find it difficult to switch vendors due to the high cost & technicalities of integrating with new the API’s and programming languages. Manual processes such as key ceremonies, algorithm implementation and policy updates create inefficient workflows and add further to the inflated costs.
