Abstract: Disclosed approaches for validating initialization vectors determining by a configuration control circuit whether or not an input initialization vector is within a range of valid initialization vectors. In response to determining that the initialization vector is within the range of valid initialization vectors, the configuration control circuit decrypts the ciphertext into plaintext using the input initialization vector and configures a memory circuit with the plaintext. In response to determining that the first initialization vector is outside the range of valid initialization vectors, the configuration control circuit signals that the first initialization vector is invalid.

Abstract: Systems and methods use negative feedback to create generic rules for a high dimensional sparse feature space. A system receives a set of fingerprints, where a fingerprint can be a set of features of a file. The fingerprints can be clustered according to similarity. For each cluster, a proto-rule is created that has a condition for each feature. The proto-rule is simplified using negative feedback to create a well-formed rule having a comparatively small subset of the conditions in the proto-rule that are useful in determining malware. The well-formed rule can be added to a set of rules used in a malware detection system.

Abstract: Corporate information technology (IT) networks can protect sensitive data sent to computers located outside of the corporate IT network. For example, a computer located outside of the corporate IT network may receive a message that instructs the computer to operate in a data protection mode in which the computer reduces a frame rate of a monitor of the computer from a first frame rate to a lower second frame rate. In this example, the computer receives sensitive information that includes sensitive visual content to be displayed on the monitor and displays the sensitive visual content on the monitor configured to operate at the second frame rate.
