Abstract: A method includes programming first and second values and a first compare enable command into respective first operand, second operand, and first compare enable command registers in a hardware comparator circuit. The method includes determining that a first match exists corresponding to the first and second values, programming a third value into the first operand register and a fourth value into the second operand register, and programming a second compare enable command into a second compare enable command register in the hardware comparator circuit. In response to a determination that a second match exists corresponding to the third and fourth values, the method includes asserting a success interrupt signal, programming a fifth value into the first operand register and a sixth value into the second operand register and programming a second compare enable command into a second compare enable command register in the hardware comparator circuit.

Abstract: In some examples, a method includes determining, during a boot sequence of a controller, a hash value for data of a block of a flash storage device, the block including executable code, determining a bit pattern based on a randomly generated number, extracting a subset of data bits of the hash value according to the bit pattern to obtain a snippet, and storing the snippet to a secure storage device.

Abstract: An integrated circuit includes: a processor; a memory coupled to the processor; and a stack memory allocation controller coupled to the processor and the memory. The stack memory allocation controller has: a stack use manager configured to monitor activities of the processor. The stack memory allocation controller also has a virtual memory translator configured to: obtain a first mapping of pointers to a first sub-set of memory blocks of the memory assigned to a memory stack for a thread executed by the processor; and determine a second mapping of pointers to a second sub-set of memory blocks of the memory assigned to the memory stack and different than the first sub-set of memory blocks responsive to the monitored activities.

Abstract: Techniques related to a technique comprising dividing an update into a number of portions, generating, for the first portion, a first portion hash value, generating, for the second portion, a second portion hash value, generating a first branch hash value comprising a hash of a concatenation of the first portion hash value and the second portion hash value, generating a root hash value by concatenating the first branch hash value and a second branch hash value, generating a signature based on the root hash value and a private key, generating an update header comprising the signature, the root hash value, and a hash tree comprising first and second portion hash values, the first branch hash value, and the root hash value, transmitting the update header to a client device for authentication, and transmitting one or more of the number of portions to the client device.

Abstract: An integrated circuit includes: a processor; a receiver coupled to the processor; and memory coupled to the processor. The memory stores resource coordinator instructions that, when executed by the processor, cause the processor to: maintain a plurality of active secure sessions; identify a priority session trigger; and allocate receiver resources for incoming packets related to the plurality of active secure sessions based on the priority session trigger.

Abstract: In at least one example, a method includes establishing, by a sniffer provisioning server (SPS) of a first wireless device, a trusted relationship between the first wireless device and a sniffer tool using a public key of the sniffer tool. An out-of-band (OOB) key exchange provisions the public key of the sniffer tool to the wireless device. The method further includes obtaining, by the SPS, key material uniquely related to a communication session established between the first wireless device and a second wireless device using a shared password. The key material excludes the shared password and a session key uniquely related to the communication session. The method further includes publishing, by the SPS, the key material over a channel to the sniffer tool based on the trusted relationship. The channel is secured using the public key of the sniffer tool.
