it came up lately in a discussion, and I couldn't put a name to it: a means to use symmetric crypto without exchanging keys:
- Alice encrypts M with key A and sends it to Bob - Bob encrypts A(M) with key B and sends it to Alice - Alice decrypts B(A(M)) with key A, leaving B(M), sends it to Bob - Bob decrypts B(M) with key B leaving him with M. Are there algorithms for this already? What's the scheme called? I searched Schneier (non-extensively) but couldn't find a reference.
