摘要： Secrets such as secure session cookies for a web browser can be protected on a compute instance with multiple layers of encryption, such as by encrypting key material that in turn controls cryptographic access to the secret. A compute instance can be instrumented to detect when a process attempts to decrypt this key material so that the process requesting decryption can be compared to authorized or legitimate users of the secret.

摘要： In general, the invention describes encryption engines that adaptively synchronize signals and suppress glitch propagation in a data decryption pipeline. An apparatus includes a decryption data path having a plurality of computational stages arranged in a pipeline configured to decrypt an encrypted block of data to form a decrypted block of data. One of the computational stages included in the pipeline of the decryption data path includes multiple asymmetric logical paths. A first signal traverses a first logical path and a second signal traverses a second logical path having a greater number of logical units than the first logical path. A glitch suppression register of the apparatus is configured to synchronize the first signal with respect to the second signal such that the first signal and the second signal arrive at a downstream logic element of the computational stage of the decryption data path at substantially a same time.

摘要： Examples relate to multiple microprocessor architecture for cold storage of digital currency. A hardware wallet may include a first microprocessor configured to establish a secure connection with a mobile device connected to a network having access to a blockchain and a second microprocessor configured to generate a private key and a public key for communication of transaction data onto the blockchain. The second microprocessor may initially use a hash function and the private key to encrypt the transaction data and produce a digital signature independent from the first microprocessor and subsequently provide the digital signature and the public key to the first microprocessor for communication onto the blockchain via the secure wireless connection with the mobile device. The second microprocessor may also encrypt and store the private key securely within the wallet's memory such that the private key is readable only by the second microprocessor.

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.

摘要： The disclosure relates to a client device (110) configured to store data in a database (125) of a data storage server (120). The data storage server stores security sensitive data in one or more encrypted data structures of the database. The client device is configured to determine whether data to be stored in the database comprises security sensitive data to be stored in an encrypted data structure of the database and to encrypt this security sensitive data with an encryption key. Furthermore, the client device is configured to provide the data, including the encrypted security sensitive data, and an identifier of the encryption key to the server for storing, based on the identifier of the encryption key, the security sensitive data in the encrypted data structure of the database. Advantageously, the encryption of the security sensitive data already at the client device allows for a secure protection of the data.
