Abstract: The techniques disclosed herein are directed to devices, circuits, systems, and techniques to mitigate the impact of side-channel attacks on a cryptography function in a target system. The Razor flip-flops are inserted into critical paths of the cryptography function of the target system, including at rest blocks such as key vaults and data vaults, and also including registers and/or pipelines used for calculations within the cryptography functions. Errors detected by the Razor flip-flops are processed by error detection logic in the cryptographic function, which continues the calculations until completion. The generated key and data value pairs resulting from detected errors are discarded, silently ignored without disrupting the calculation process. The schemes disclosed herein mitigate the impact of side-channel attacks with a digital logic based implementation, with reduced complexity and reduced cost.

Abstract: A system has an outer catheter and an inner aspirating clot retrieval catheter having an expansile distal tip for flow restriction, improved aspiration efficiency, and a large mouth into which a clot or other obstructions can be retrieved. The clot retrieval catheter can have a support tube proximal of the tip. The expansile tip can be a strut framework, and a flexible, low-modulus cover is disposed around at least a portion of the tip strut framework and the proximal support tube. The distal end of the tip can be encapsulated by a low-friction elastomeric lip for atraumatic contact with the walls of a blood vessel. The tip has a collapsed delivery configuration and expands radially into a deployed configuration. The tip strut framework, support tube, and cover can all have characteristics which enhance the deliverability of the clot retrieval catheter to the target.

Abstract: Embodiments described herein are directed to transferring the ownership of a computing device from one entity to another entity. For example, a security processor is utilized to boot the computing device. During a boot session, the security processor loads and executes boot code, which determines whether specialized firmware authorized by the current owner indicates whether a transfer of ownership is to occur. In response to determining that the specialized firmware indicates that a transfer of ownership is to occur, the secure processor loads and executes the specialized firmware. The specialized firmware, when executed, causes the security processor to program a set of fuses with the public key of the new owner. Execution of the specialized firmware also causes the security processor to invalidate the public key of the original owner, which is stored in another set of fuses.
