  • Patent number: 9497029
    Abstract: Various embodiments are generally directed to hardening the performance of calculations of a digital signature system for authenticating computing devices against side-channel attacks. An apparatus comprises a processor circuit and an interface operative to communicatively couple the processor circuit to a network; a storage communicatively coupled to the processor circuit and arranged to store instructions operative on the processor circuit to digitally sign a message to create a first signature using a modular arithmetic operation arranged to compensate for a value of a variable greater than a modulus without use of a branching instruction; and transmit the first signature to a verifying server via the network. Other embodiments are described and claimed herein.
