Nitrokey is an open-source USB key used to enable the secure encryption and signing of data. The secret keys are always stored inside the Nitrokey which protects against malware (such as computer viruses) and attackers. A user-chosen PIN and a tamper-proof smart card protect the Nitrokey in case of loss and theft.
A "Chosen IV" attack relies on finding particular IV's which taken together probably will reveal information about the secret key. Typically multiple pairs of IV are chosen and differences in generated key-streams are then analysed statistically for a linear correlation and/or an algebraic Boolean relation (see also Differential cryptanalysis ...
A secure attention key (SAK) or secure attention sequence (SAS) [1] is a special key or key combination to be pressed on a computer keyboard before a login screen which must, to the user, be completely trustworthy. The operating system kernel, which interacts directly with the hardware, is able to detect whether the secure attention key has ...

In the film, NYPD Detective John McClane (Bruce Willis) attempts to stop a cyber-terrorist, Thomas Gabriel (Timothy Olyphant) who hacks into government and commercial computers across the United States with the goal of starting a "fire sale" cyber attack that would disable key elements of the nation's infrastructure.
The HPKP is not valid without this backup key (a backup key is defined as a public key not present in the current certificate chain). [4] HPKP is standardized in RFC 7469. [1] It expands on static certificate pinning, which hardcodes public key hashes of well-known websites or services within web browsers and applications. [5]
S/KEY is a one-time password system developed for authentication to Unix-like operating systems, especially from dumb terminals or untrusted public computers on which one does not want to type a long-term password. A user's real password is combined in an offline device with a short set of characters and a decrementing counter to form a single ...
