Techniques are provided for authentication using pairwise secrets constructed from partial secrets. One method comprises obtaining, by a first entity of a communication between the first entity and a second entity, partial secrets associated with the first and second entities; generating a constructed secret for the communication by applying a cryptographic function to the partial secrets associated with the first and second entities; and authenticating the communication using the constructed secret. A control entity may assign a substantially unique partial secret to each of multiple first and second entities and distribute at least a subset of the assigned partial secrets to at least some of the first and second entities. A communication between given first and second entities can be authenticated using a pairwise constructed secret for the given communication generated by applying the cryptographic function to the partial secrets associated with the first and second entities.
