摘要

A request to perform an operation with a cryptographic item may be received. A request for approval to perform the requested operation with the cryptographic item may be transmitted to a set of entities based on a policy associated with the cryptographic item. Indications of approval to perform the requested operation may be received from corresponding entities of the set of entities. A determination as to whether a number of the received indications of approval to perform the requested operation with the cryptographic item satisfies a threshold number may be made. In response to determining that the number of the received indications of approval from the corresponding entities of the set of entities satisfies the threshold number, the requested operation may be performed with the cryptographic item.

說明書

Advantages of the present disclosure include, but are not limited to, improving the security of cryptographic items stored by a key management system. By requiring quorum approval before sensitive operations are performed by the key management system, a malicious administrator is unable to unilaterally perform sensitive operations that may compromise the security of the cryptographic items. Thus, the utilization of a quorum approval results in an enhanced security for cryptographic items of the key management system since multiple approvals are required before sensitive operations are performed by the key management system.

FIG. 1 illustrates an example environment 100 to provide a key management system. The environment 100 may correspond to network servers that provide an interaction between an application and the key management system as well as between the key management system and one or more approving entities.
