Abstract

A cryptographic coalition administrator for managing information access across multiple organizations includes a communications interface configured to communicate electronically transmit and receive information, a memory configured to store pairs of public and private cryptographic keys associated with different levels of access, and a key manager configured to : distribute cryptographic key sets, of public cryptographic keys and private cryptographic keys, to first and second organizations of members; determine a first group of members in the first organization to have authorization to exchange information with a second group sharing cryptographic parameters, and public and private cryptographic keys; and distribute a first cryptographic key set, from the cryptographic key sets, to the first group, the first group having a first sensitivity level at least as high as a second sensitivity level associated with the first cryptographic key set.
