Abstract
A computer node comprising multiple software modules may receive a cryptographic key from a hardware security module. The computer node may use the cryptographic key to produce two key portions, which are distributed to two software modules. These software modules and an optional additional software module may use the key portions in order to encrypt an initial message. The key portions and their locations in memory are periodically updated in order to provide improved cryptographic security.
