摘要： Cryptographic key management techniques are described. In one or more implementations, an access control rule is read that includes a Boolean expression having a plurality of atoms. The cryptographic keys that corresponds each of the plurality of atoms in the access control rule are requested. One or more cryptographic operations are then performed on data using one or more of the cryptographic keys.

摘要： In embodiments of scalable random number generation, a system includes one or more entropy pools that combine entropy data, which is derived from entropy sources based on event data. A root pseudo-random number generator (PRNG) maintains a seeded entropy state that is reseeded by the entropy pools, and a seed version identifier updates to indicate a current seed version of the root PRNG. Processor PRNGs are instantiated one each per logical processor in a kernel of the system, where each processor PRNG maintains a PRNG entropy state that is reseeded from the root PRNG, and a processor PRNG generates a random number from a respective PRNG entropy state when invoked.
