    摘要： In an example, a system and method are provided for validating the sender of a message, such as an e-mail, text message, voice mail, network message, internet posting, or other electronic message. An authenticity server engine may first prescreen the message with anti-spam, anti-malware, and other filters. The screened message is then provided to the end user. If the end user deems the message suspicious, he may request additional validation. The authenticity server engine may then apply an example four-phase validation scheme, including analyzing header data for consistency with the message body, analyzing public data sources, analyzing private data sources, and receiving a result of an off-channel challenge to the sender. The server may then assign the message a sender validity confidence score.

    摘要： Particular embodiments described herein provide for an electronic device that can be configured to intercept a process, store execution profiling for the process if the process involves a privileged resource or a privileged operation, and analyze the code involved in each stack frame to determine malicious activity. If the process does not involve a privileged resource or a privileged operation, then the process is not analyzed.

    摘要： Technologies are provided in embodiments to establish trust between a trusted execution environment (TEE) and a peripheral device. Embodiments are configured to communicate with an attestation server to generate an encryption key, and to establish, using the encryption key, a secure connection with an authentication server to enable communication between the authentication server and the peripheral device. Embodiments are also configured to receive a pairwise master key if the peripheral device is authenticated and to receive a trusted communication from the peripheral device based, at least in part, on the pairwise master key. Embodiments may also be configured to identify a connection to the peripheral device before the peripheral device is authenticated to the authentication server, receive an identifier from the peripheral device, and establish a connection to an attestation server based on at least a portion of the identifier.
