Hi, Have you had any experience with WinXP Embedded? I am considering it for a new kiosk-like project, for a FLASH based device, but I am mostly concerned about the security aspect. Tipically, WinXP requires regular updates in order to be kept one step ahead the current exploits. Is it safe to keep it unpatched instead? Regards, Legrandin


How to use 3DES in a micro?

I need to implement some type of embedded security over a serial link, like 3DES (or DES or AES), and really don't know where to start to look, so some pointers would be really helpful. - Can this be implemented only in software? (code space?) - Does anyone sell a library that can be used? - Do the two units (which can be any two units) have to know the keys in advance? Thanks

Hi, I'm going to port a VoIP application (with security and a bit of DSP stuff) to a rather small embedded platform. So far, two good candidates are IXP425 and MPC8541E (both running at 500Mhz), though the older MPC8272E is still appealing. I can only spend time on one but I have no experience with neither of them. Actually I cannot figure out how to compare these new light-weight "network...

Sorry if this post is off topic. I recently conducted a war dial as part a security audit of modems connected to our companies telephone lines. While I was able to identify most of the modems found there are a few I need help with, it has been suggested to me that they may be some kind of embedded systems. If anyone recognises any of these or can give me any idea what they are, I'd be...

Hi All, I am studying Bluetooth security protocol these days. I found that there is no much specified data about protocol detail/procedure. I think, when I finshed the study of Bluetooth, I can only know more about Bluetooth operation, but I still can't develop a Bluetooth related tools, is that right? Best regards, Boki.

Further to my last (hopefully this posting is visible amongst all the sporge). The concern is that in my client's current product, RF communications with the RTU's are in plaintext visible to anyone with a capable receiver. The Master Station is a hand-held device with a cell modem and a proprietary RF transceiver to connect with the RTU's. It does use a secure shell for Host messages. ...


Cryptography: serial-link validation

I'm not even sure of the correct term to use. I want to build some security into a product that uses a pair of controllers communicating by RS-232. I'd like the "slave" controller to require the "master" controller to perform some sort of validation before the slave will respond with any but the most basic of keep-alive messages. This whole thing doesn't need to be perfect: it just ne...

I hope all of you are doing well. I have come across a challenging project and I need your advice. Its a security application with the following scenario: Doors with computerized locks (biometric/swipecard/pincode), the locks access a central server for access authentication. The catch is that the communication between the lock (embedded computer/PCB etc) and the server has to be wireles...

Hi, I know that an 8bit microcontroller can be used to be a simple web server. This is very good for putting embedded controller devices on a network. What about if I need to have security in there, such as SSL? I don't thik an 8bit micro can handle SSL. Is there any chip out there i can use to offload my SSL stuff? Thanks, Mike

Wondered what the state of the art is on keeping embedded code secret. Who does it better these days? I see some secure processors from Atmel and a few others, but they seem more oriented to securing comms and data than in securing their own code.

One of our devices is controlled from a PC using the serial interface. One of our customers has security concerns as the protocol used, though proprietary, is not encrypted. As adding encryption to our - dated - device is not a viable option, I have gotten the task to find out if we can find some third party solution that plugs into the serial stream and encrypts/decrypts the data stream w...

Hi group, We have a need for a fingerprint scanner to be connected to our controller, running ROM-DOS, and only having RS232 connectivity available. The idea is for staff to id themselves as part of a security protocol to initiate critical processes. The fingerprint ids to match are relatively low, about 10 to 15 at most, and some storage space on the controller can be provided. Anyon...
