I start with the fact that I understand how flash devices (pendrives) can be encrypted with software, for example Bitlocker. Simply, the encryption key is the password given during encryption and decryption by user, where the… Continue reading How is it possible that hardware-encrypted flash devices are safe?
It can be understood that if i delete some data, those bytes may not be written by other data can be extracted because the data actually resides on those sectors/cells.
But i wounder how the bytes can be recovered from the s… Continue reading Understanding the philosophy of recovering data
A lot of work has been done on: how to ensure a secure boot for FPGAs. However, as far as I know, it seems that it is applied to the SRAM based FPGAs.
I wonder, is there such concern about the Non-Volatile-Memory based FPGA… Continue reading Does NVM based FPGA require a secure boot process?

The proper way to secure erase a SSD is to issue the SECURITY ERASE UNIT command. Then the SSD controller should send a BLOCK ERASE command to all physical blocks.
One caveat: the SSD has to be connected directly to the SATA interface. Do… Continue reading Howto restore factory default state of an USB pen drive?
Are there any commands, tools or python libraries to securely wipe specific files from an SD or micro SD card (devices that use flash memory)?
For example, with a regular magnetic hard drive, you can use the Wipe command to … Continue reading Linux command to wipe files on an SD Card?

A security risk with ordinary flash drives is that they have re-writable (flashble) firmware, which basically lets a hacker replace the operating system of the USB drive with their own.
Are there any USB drives that are guaranteed to be r… Continue reading Are there USB flash drives with read-only firmware?
[Pete] was building a hot tub controller, using a WEMOS board based on the venerable ESP8266. After assembly, the board was plugged into USB and [Pete] hit the flash button. No dice. Investigation with some terminal software indicated a checksum error.
Assuming the board was dead, [Pete] grabbed another — and suffered the same problem. The WEMOS boards wouldn’t program, but other boards had no issues. Sensing that something may be amiss, further research was in order. A forum post turned up discussing different programming modes for the ESP8266.
It turns out that there are different types of flash used …read more
