Abstract: Techniques for protecting data in a processor are provided. An example method according to these techniques includes performing one or more operations on encrypted data using one or more functional units of a data path of the processor to generate an encrypted result. Performing the one or more operations includes: receiving at least one encrypted parameter pair at a functional unit, each encrypted parameter pair comprising an encrypted parameter value and a challenge value associated with the encrypted parameter value, the encrypted parameter being encrypted using a homomorphic encryption technique, the challenge value being used to recover a key used to encrypt the encrypted parameter value, and performing a mathematical computation on the at least one encrypted parameter. The method also includes outputting the encrypted result.

Abstract: 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.

Abstract: Disclosed is a method for configuring an internal entity of a WiFi-enabled remote station with a certificate. In the method, the remote station receives the certificate in at least one message from a registrar acting as a certificate authority. The remote station provides the certificate to the internal entity. The internal entity securely communicates with an external entity based on the certificate.
