"PUF CRPs authentication requires trust in manufacturer since it’s him who performs the storage of CRPs".
So does it mean that we have to trust manufacturer, because he could replace the legit chip with a fake one and then calcul… Continue reading "PUF CRPs authentication requires trust in manufacturer since it’s him who performs the storage of CRPs"….?
Laser pulse/injection attacks, Xray inspection, Test-based(like JTAG scan chain) attacks, Microprobing attacks… are these invasive or non-invasive?
Just curiosity. I don’t know how to categorize.
My professor put laser pulse as non-invas… Continue reading Laser pulse/injection attacks, Xray inspection, Test-based(like JTAG scan chain) attacks, Microprobing attacks… are these invasive or non-invasive?
About timing my question is:
How can attack know the time of which certain instructions are performed by the victim?
And about the cache, how can attacker know which cache line is being accessed by the victim? Is this doable in "norma… Continue reading How can a timing/cache side-channel attack be performed? How can attack know the time of which certain instructions are performed by the victim?
Are PUFs used, EVERY time we power on the computer to verify that nothing has been tampered with (by using CRP authentication)?
Which element performs this authentication? (bios, secureboot, I don’t know)?
Where are CRPs stored? In which … Continue reading Is PUF Challenge-Response Authentication applied on every power-up event? [closed]

Since JTAG can be authenticated and encrypted, which key is used? I read that Secure Boot is used, but what is the key? Me, owner of this laptop, how can I know the key to use to access my own laptop JTAG?
1) Is this handshake (used to perform mutual authentication and to derive PTK and GTK) performed in WPA(TKIP)?
I think not, but I don’t understand why in a aircrack page it’s written that
There is no difference between cracking WPA or WP… Continue reading Does TKIP(WPA) implement the 4-way handshake? Or only RSN(WPA2) does implement it?
Why a Rogue Access Point can "intercept" all traffic? Rogue AP doesn’t know the shared key, so can’t decrypt the traffic… So what are the dangers? What harm can a Rogue Access Point do?
Continue reading What a Rogue AP can do? Can it intercept traffic? [duplicate]
Brute force attack against WPA is the most common attack against WPA/WPA2 networks. Attacker captures the 4-way handshake that allows the authentication key to be cracked offline.
During the 4-way handshake, several pieces of information … Continue reading In WPA handshake brute force attack, how can attacker find PMK if MIC is performed using only HALF of PTK?
Why is step 4 needed? What does it protect in terms of security? Doesn’t the protection arrives from the last step so when Va and Vb (so called TK, Temporary Keys) are compared?
Other thing: I read somewhere that Cb is sent immediately an… Continue reading Why is the "intermediate" challenge needed in Bluetooth ECDH since the "real" verification is performed at the end with code comparison?
