Here is the use case:
- Router vendor to support 3rd party app hosting on their Routers with apps digitally signed by Router vendor only.
- Router to support skipping signature verification for App developers/vendors during Dev phase.
- Router to enforce signature verification in production mode.
- Router vendor to build this solution on a production router image so that they don’t need to provide separate Dev/Test router image to app vendors during Dev phase.
What is the secure way to support this on embedded systems like Routers without having to create 2 separate sets of images for Dev and Production from the router vendor?
I’m not from Information Security or any IT related area. But I want to know if there is any security reason for my digital bank to demand my phone to be on "Automatic Date & Time"?
For example, if I’m abroad, i cannot transfer some money to a friend for because it says my date & time is incorrect.
Is that a badly programmed software or does it have a purpose?
Hi friends, can you share some digital marketing tools that effective?
Most tutorials on the net only mention sending the digital signature attached to the document, but without the digital signature certificate, it’ll be impossible for receivers to verify the signature. I’m assuming that the digital certificate is somehow sent alongside the signature but I can’t seem to find any source mentioning that.
In the Free Remote D&D Resources archive that Wizards of the Coast is providing, for April 30, 2020 there is a “Waterdeep Digital Backgrounds” zip file that includes artwork that one might be able to use as a background while videoconferencing. The second file (named “DnD_Video_bg-WDDH2”) looks to be a scene outside of Waterdeep proper, with people along a path, a building (maybe some kind of temple), and the wall of Waterdeep in the background. I’m presuming putting a smaller version here counts as fair use:
What is that building, and more generally where is this scene set? Is it part of the Waterdeep: Dragon Heist book or storyline? (I don’t remember seeing it in there, though probably I just missed it, but the filename saying “WDDH” makes me think it’s related.)
I am a computer science student and I have some courses names “Fundamental of electronics and digital systems, Logic design and switching circuits, System analysis and design “. I searched for books that may help me for these course and I found one named ” Digital logic and computer design by Mano”. I was wondering if anyone could suggest me some more books that will help me to master these topics. Thanks

If A encrpyts the message and creates signature using his private key and sends through the network then only B with the public key of A can decrypt that message.
But what if the attacker gets access to the public key of A and the encrypted message through the network? Will he be able to decrypt the message?
