摘要： Disclosed in some examples are methods, systems, devices, and machine-readable mediums that provide for techniques for scrambling and/or updating meta-data that enable an efficient internal copyback operation. In some examples, improved data distribution techniques decouple the scrambling key from a physical address to allow for copyback operations while maintaining data distribution requirements across a memory device. The controller may generate a seed value that is used by a scrambling algorithm to scramble the host-data and meta-data prior to the data being written. The seed value is then encoded and written to the page with encoded versions of the scrambled user data and meta-data - the random seed is written without scrambling the random seed.

摘要： Various embodiments are directed to securely generating and managing passwords using a near-field communication (NFC) enabled contactless smart card. For example, a secure password may be generated by generating a random number via a random number generator of the contactless smart card and converting the random number to one or more human-readable characters. In another example, a secure cryptographic hash function of the contactless smart card may generate a hash output value, which may be converted to one or more human-readable characters. The humanreadable characters may be used as the secure password or it may be transformed to add more layers of security and complexity.

摘要： Described are techniques for securing a most recent block in a data structure such as a blockchain. Techniques include configuring a data processing node that is deployable to a physical location, with a module that generates a verification signing key (VSK) pair, the VSK pair including a private VSK key that is known only to the data processing node, and a public VSK key, receiving by the data processing node, an indication of the deployment to the physical location, generating in response to the indication, by the data processing node the verification signing key (VSK) pair, and transmitting from the data processing node the public VSK key to one or more electronic devices. These techniques assure to a high degree that the generated private key remains unknown and thus can be used to secure the most recent block that is added to a data structure such as a blockchain.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for symmetric cryptography using varying sized symbol sets. To protect against a brute force or other similar type of attack, multiple symbol sets of varying sizes can be used for encrypting/ decrypting data. For example, different portions of the data (e.g., data blocks representing multiple symbols, set of bits representing a single symbol) may be encrypted/ decrypted using different symbol sets that include different numbers of unique symbols. Using varying sized symbol sets adds additional complexity to the encryption process, thereby greatly increasing the difficulty in decrypting the encrypted data with a brute force attack.

摘要： Die Erfindung betrifft eine Lösung zur Nutzung quantensicherer kryptographischer Schlüssel mit telekommunikativen Endgeräteeinrichtungen (1), welche selbst nicht über quantentechnische Mittel zu deren Erzeugung verfügen. Dazu bezieht die jeweilige Endgeräteeinrichtung (1) die quantensicheren Schlüssel durch Anforderung bei einem fortwährend quantensichere Zufallszahlen erzeugenden, von zwei in einer Quantum Key Distribution Verbindung stehenden Netzwerkknoten (21, 22) gebildeten QKD-Verbund. Dies geschieht indem von den Netzwerkknoten (21, 22) auf wenigstens zwei zueinander disjunkten Wegen mehrere voneinander verschiedene, aus von dem QKD-Verbund erzeugten Zufallszahlen gebildete bitweise XOR-Verknüpfungen über VPN-Verbindungen an die quantensichere Schlüssel anfordernde Endgeräteeinrichtung (1) übertragen werden und die Endgeräteeinrichtung (1) aus diesen XOR-Verknüpfungen einen auch bei den Netzwerkknoten (21, 22) vorliegenden quantensicheren Bezugsschlüssel extrahiert. Dieser wird zur symmetrischen Verschlüsselung in einem nachfolgenden Übertragungsvorgang von einem der Netzwerkknoten (21, 22) an die Endgeräteeinrichtung (1) übertragener Daten verwendet wird, die eine größere Anzahl von dem QKD-Verbund erzeugter Zufallszahlen umfassen, aus denen die Endgeräteeinrichtung (1) mehrere, auch in den Netzwerkknoten (21, 22) vorliegende Schlüssel extrahiert und in einem manipulationssicheren Speicher ablegt.
