Abstract: Technologies for encrypting communication links between devices are described. A method includes generating a first initialization vector (IV), from a first subspace of IVs, for a first cryptographic ordered flow, and a second IV, from a second subspace of IVs that are mutually exclusive from the first subspace. The first and second cryptographic ordered flows share a key to secure multipath routing in a fabric between devices. The method sends, to the second device, a first packet for the first cryptographic ordered flow and a second packet for the second cryptographic ordered flow. The first packet includes a first security tag with the first IV and a first payload encrypted using the first IV and a first key. The second packet includes a second security tag with the second IV and a second payload encrypted using the second IV and a second key.
