    > Now your cache/registers/SRAM are maintained. Power up with JTAG or a custom/debugging bootrom/mode that hopefully doesn’t overwrite much/any and dump away. If you care about sec…

    To get 192-bit security with RSA you'd need 7680-bit RSA key and with ECC you need 384-bit key as mentioned in the article. That assumes classical attacks only. For quantum attacks…

    What the article describes is not particularly difficult to implement. But claiming that storing the firmware in a way that prevents the user from updating it via software somehow …

    > That's why so few of them tend to advertise transmit capabilities. Any SDR that has transmit capability freely advertises it and there are many of them. The makers of one of them…

    This polling is not done by the CPU, this is a common misconception. In a typical modern system the only polling that happens with USB is done by the USB host controller and only w…

    This has nothing to do with "weakening of ECC". Dual_EC_DRBG is an RNG that happens to use Elliptic Curves but its problems have nothing to do with that, they have to do with the d…

    Yes, for a wifi client (like in the article) you're right. manuel_w was talking about bridging on the AP and for that you do just enable bridging and it works fine.

    The 802.11 header has 4 MAC addresses: Source Address (SA), Destination Address (DA), Transmitter Address (TA), Receiver Address (RA). The TA and RA are those of the Wifi station a…

    The mathematics of Shor's algorithm have been known for decades. The challenge is in building the hardware, not in the math. There are tens of billions of dollars worth of abandone…

    > it still has the decryption keys No, they (usually) work similar to PGP/GPG, i.e. each file is encrypted with a different AES key and the AES key is encrypted with a public RSA k…

    The UID is 256-bit. With a proper random number generator you don't do anything additional to avoid collisions. Hardware random number generators are standard for crypto processors…

    Comment #12113130

    The ECC algorithms used today rely on the "Elliptic Curve Discrete Logarithm Problem" and are very much vulnerable to (a version of) Shor's algorithm. Some would even say they are …

    Yes, but if you want your sessions that are captured today to remain confidential when quantum computers do become reality then you need to use post-quantum key exchange methods to…

    Symantec already agreed to start using Certificate Transparency in the near future, as per Google's request. This is a good thing.

    Firefox packages its own copy of the libraries it uses, including the stagefright library. They patched their copy in the new release.

    This sounds like DHT, which has existed for a while now. https://en.wikipedia.org/wiki/Distributed_hash_table
