We introduce a notion of one-way crossed modules of groups. Then we cons¬truct two general examples of this new cryptographic primitive, giving suggestions for new candidates of one-way (non-abelian) group homomor-phisms. Based on this new notion, we describe the brand of new general cryptographic protocols and then focus on their practical instances.
