Abstract

Share values for use in a cryptographic operation may be received and the cryptographic operation may be performed based on the share values. A pseudorandom number that is to be used by the cryptographic operation may be identified and the pseudorandom number may be generated based on a portion of the share values that are used in the cryptographic operation. The cryptographic operation may then be performed based on the generated pseudorandom number.
