Let’s say I want to protect the contents of my Desktop PC which I use in quite many occasions remotely.
I want to use Bitlocker with a startup key that only "activates" at a specific moment in time.
The setup I am thinking would … Continue reading How secure is a bitlocker startup key on a mountable encrypted container?
Another thread addresses the question of what can count as "military-grade encryption." In this case, I see that CyberLink Power2Go software boasts "advanced military-grade 256-bit encryption." TechRadar clarifies that … Continue reading Military-grade encryption on Blu-ray discs?

Some user uses a sensitivity label to protect/encrypt the document.
Admin redefines sensitivity lab… Continue reading What will happen to existing documents when AIP sensitivity label is redefined? [migrated]
As the title implies, I would like to design a secure file storage/sharing platform. This is an abstract design question, so details regarding programing languages or platforms are not particularly relevant, unless they represent the only … Continue reading How to design a secure file storage/sharing platform
I was wondering whether there exists a symmetric encryption scheme such that
there is 1 sender and n receivers. Each receiver has 1 random and independent symmetric key. The sender knows the symmetric keys of all receivers in advance.
the… Continue reading multi-user deterministic symmetric encryption
I need to secure logs on a IoT device (Infineon TC233). It has 2 MB flash and a HSM. We are at the design stage of development.
Since logs will be primarily event & data logs, the size of the log file is likely to be in a few KBs. Addi… Continue reading Secure logs on an embedded IoT device
VirtualBox has an option to encrypt the drive of a VM.
When I installed Debian or Ubuntu, I have the option to say that I want the full disk encrypted.
I’m thinking that both do pretty much the same thing in this situation and they are not… Continue reading When using VirtualBox, is it better to use the VirtualBox encryption or the OS disk encryption?

I’m using Debian + sddm + KDE with ONLY home directory encrypted with gocryptfs.
Decrypting is performed with gocryptfs as follows:
PC boots as usual and starts the sddm service
I enter my login credentials (which equal to my encryption p… Continue reading Attack on home dir encryption with sddm pam_mount by using password in /etc/shadow
Say I want to keep some files on cloud for portability but I do not trust the encryption (if there is any) provided by cloud service provider (avoid possibility of backdoor to read my files), so I am thinking to use some virtual drive encr… Continue reading Using virtual drive encryption software with cloud storage
