Each of the cryptographic items may be assigned to a different group. Each of the groups may have a different quorum policy and different entities to approve the transaction. For example, Item A may be assigned to a first group having three approving entities (e.g., Entities 1-3) and a quorum policy specifying a threshold value of two approvals are required before the operation is performed. Item B may be assigned to a second group having four approving entities (e.g., Entities 4-7) and a quorum policy specifying a threshold value of three approvals are required before the operation is performed. In embodiments, the corresponding threshold values for all the cryptographic items involved in the requested operation must be satisfied before the operation is performed.
