Tóm tắt: For decades cryptography strived for its goals by packing complexity into the exposed program, all the while pressing down the size of the secret key. Alas, modern technology (1) makes small keys a secondary requirement, (2) allows for layering of program logic, and (3) offers privacy and security offenders clever eavesdropping tools; altogether warranting a re-examination of the relative roles of the “passive” key and the “active” algorithm. We describe a working system where the nominal ke
