I have seen around some 5G cellular kits that can be connected to SBC (Single Board Computers) in order to make a WIFI hotspot. From the one side, they provide 5G cellular connection and from the other side, they support WIFI connection.
D… Continue reading Do 5G cellular kits than are connected to SBC, support encryption when the signal goes via them to the wifi?
When I make a video call through a cellular GSM/4G network, is there any end-to-end encryption? If yes, what kind of algorithms and CPUs are used?
Continue reading Are the video calls made in a 3G/4G network encrypted end-to-end?
Recently I got a friend request from a person I do not even know and of course he was not in my friends list (I mean the people I have accepted in my skype in order to chat or talk live) and he immediately called me. I didn’t answer of cou… Continue reading What security issues are there when accepting skype calls from people I do not know?
Supposing I have connected my laptop to the ethernet cable and all the traffic in the ethernet cable is encrypted (let’s say VPN, HTTPS, etc.). Can someone who is eavesdropping the traffic with physical access to the Ethernet cable (via an… Continue reading Can someone who is eavesdropping signals from Ethernet cable, gather sensitive information [duplicate]
I have enabled a function in my mobile phone, that uses my home Wi-Fi network to make calls when the cellular signal does not exist. As far as I know, the cellphone provider charges me as though I make calls through its cellular network.
W… Continue reading Are phone calls via WiFi VOIP encrypted by A5/1, A5/2, and A5/3?
I am using a paid (non-free) antivirus on my Android 13. I am curious however, what would be the signs/"symptoms" in case I have data leakage/security issues/trojan on my smartphone? How can someone identify that?
I am trying to build a commercial encryption device. Ok, I know how to write code, how to transform encryption algorithms from the book into code and construct electronics. But my question is: what should I take care of in order to impleme… Continue reading What standards should a commercial encryption device meet?
Can an android antivirus detect or even prevent data-leakage of a mobile phone? Moreover if the user has installed .apk outside playstore. I searched on google, but answers like this: https://www.kaspersky.com/resource-center/threats/data-… Continue reading Can an android based antivirus prevent data-leakage?
The idea is that I used a friend’s laptop via which I copied data from my mobile phone to an external HDD. I didn’t know how else I could achieve this, to copy data (for backup) from my mobile phone to the external HDD.
Is it possible that… Continue reading Is data stored on laptop when I copy files directly from mobile phone to an external HDD
I am interested in algorithms that consume as less space available on a memory, for low consuming power devices such as wireless nodes. From a search I have found this article here:
