摘要： A distributed technique for implementing a cryptographic process performs operations in parallel on both valid and irrelevant data to prevent differentiation of the operations based on an encryption key content. A control entity switches or points valid data to appropriate CPU(s) that are responsible for operations such as squaring or multiplying. Irrelevant data is also switched or pointed to appropriate CPU(s) that execute operations in parallel with the CPU(s) operating on the valid data. The distributed technique contributes to obscuring side channel analysis phenomena from observation, such that cryptographic operations cannot easily be tied to the content of the encryption key.

摘要： An apparatus and method for configuring a wireless station for use within a wireless local area network are disclosed. In at least one exemplary embodiment, a pairwise master key is generated by the wireless station and an access point within the wireless local area network. The pairwise master key may be based, at least in part, on a transient identity key pair of the wireless station. The transient identity key pair may be generated by the wireless station in response to receiving a message from the access point. In some embodiments, a public transient identity key of the transient identity key pair may be provided to additional access points to enable the wireless station to authenticate with the additional access points.

摘要： A new enrollee device is configured for a communication network using an electronic device and a network registrar. The new enrollee device is a headless device that lacks a first user interface for configuring the new enrollee device for the communication network. The electronic device obtains, at a sensor, sensor information that is indicative of a device key associated with the new enrollee device. The electronic device determines the device key based on the sensor information. The device key is provided to the network registrar to cause the network registrar to configure the new enrollee device for the communication network.

摘要： Various features pertain to cryptographic ciphers such as Advanced Encryption Standard (AES) block ciphers. In some examples described herein, a modified masked AES SubBytes procedure uses a static lookup table that is its own inverse in GF(22). The static lookup table facilitates computation of the multiplicative inverse during nonlinear substitution operations in GF(22) In an AES encryption example, the AES device combines plaintext with a round key to obtain combined data, then routes the combined data through an AES SubBytes substitution stage that employs the static lookup table and a dynamic table to perform a masked multiplicative inverse in GF(22) to obtain substituted data. The substituted data is then routed through additional cryptographic AES stages to generate ciphertext. The additional stages may include further SubBytes stages that also exploit the static and dynamic tables. Other examples employ either a static lookup table or a dynamic lookup table but not both.

摘要： A user device can be configured for network access, such as for guest network access. In one example, a first device receives an indication of a transaction that uses the first device. The first device communicates a request for network access to an access point of the network in response to receiving the indication of the transaction. The first device then receives a first key from the access point. The first device provides the first key to the user device. The user device is to use the first key to obtain the network access to the network.

摘要： Various features pertain to defending a smartphone processor or other device from a transient fault attack. In one example, the processor is equipped to detect transient faults using a fault detection system and to adaptively adjust a control parameter in response to the transient faults, where the control parameter controls a physical operation of the processor (such as by gating its clock signal) or a functional operation of the fault detection system (such as a particular Software Fault Sensor (SFS) employed to detect transient faults). In some examples, in response to each newly detected fault, the detection system is controlled to consume more processor time to become more aggressive in detecting additional faults. This serves to quickly escalate fault detection in response to an on-going attack to promptly detect the attack so that the device can be disabled to prevent loss of sensitive information, such as security keys or passcodes.

摘要： A method, apparatus, and system for utilizing a register virtualization mapping to improve defense against return-oriented programming-based attacks is disclosed. A register virtualization mapping, which is bijection between nominal registers and physical registers, is generated for a subroutine call when the subroutine call is detected. The register virtualization mapping is applied to instructions within the subroutine call. The register virtualization mapping is stopped for the subroutine call at the return of the subroutine call.
