Hi, in our design we would like to replace a smartcard by a kind of security chip or security module. The chip has to provide: - unique ID / serial number - secure key management The idea is to store data on the device in a way that they cannot be read (hence encryption) or copied to a similar device (hence unique ID) without the particular security chip being involved. The actual ...

I want to add security to an M16C project. The manual in Figure 1.30.2 shows the 7 security bytes ID1 thru ID7 on the left-hand side, or what I would call the lower address side of the four bytes, whereas the text defines the addresses as the high side. The two options in the sect30.inc file would be either: One: .section vectors,ROMDATA ...

I heard there is a security issue with the MSP430. Anybody able to verify this rumour? Allegedly, if the JTAG is disabled there exists a back door to download the code and it has something to do with the interrupt vector table. Please help me verify if this is a real issue or not. Need to make quick decision for large volume design, soon. Cannot afford any security issues in this desi...

Hi, Not sure exactly how I want to ask this question; i.e., how best to differentiate the examples where X should be allowed vs X should be prohibited. I have a capabilities based security model. Each capability has "authorizations" associated with it (trying to avoid using the word "capability", again : < ). These authorizations are defined by the entity that creates the capability

Hello all, I have developed an embedded system that I wish to protect from reverse engineering and piracy, while at the same time allowing end users to easily update the units with newer versions of my software. I have come up with a security scheme that I believe will be a "win" for everybody, but I would like to get some feedback from your guys. The hardware for my embedded system is m...

We have an application where we would like to use a low cost security IC to protect IP. The Maxim DS2432 or DS28E01-100 are possible candidates. A very small SPI device would also be OK. As usual, Maxim doesn't really want to sell these. They quote a lead time of 26 weeks. Avnet quotes 100 weeks!, Can you get anything but samples from Maxim? Does anyone have a suggestion? We don't re...

Hi All, I'm thinking about building a security system with multiple (2-3) webcams and some lights with a few sensors around. The idea is that in the event of an incident detection, the lights are turned on (if at night) and streams from the cameras recorded to a flash memory of some description, maybe compact flash. Webcams are preferred because they're dirt cheap but do require dri...

Hi, I would like to program FLASH memory of a HC908AZ60 controller via the monitor function of the controller. Reading/writing RAM works fine. However, bypassing the security so that I can write FLASH does not seem to work in any way. I tried 8 x $00 as well as 8 x $FF. Also, applying a RESET after entering monitor mode and then trying to bypass securtiy doesn't seem to have any effec...

I'm looking for good references on micro code security. My reading leads me to various conclusions, including: 1. Mask-ROM parts are easiest to read-out intrusively, EPROM and flash are intermediate-difficulty (with EPROM being perhaps slightly easier) and RAM-based technologies are the hardest. 2. Any microcontroller that isn't specifically designed to resist invasive read-out technique...

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?

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...
