A Digital Signature Based on a Conventional Encryption Function
TL;DR: A new digital signature based only on a conventional encryption function (such as DES) is described which is as secure as the underlying encryption function -- the security does not depend on the difficulty of factoring and the high computational costs of modular arithmetic are avoided.
Journal ArticleDOI
Hiding information and signatures in trapdoor knapsacks
TL;DR: Specific instances of the knapsack problem that appear very difficult to solve unless one possesses "trapdoor information" used in the design of the problem are demonstrated.
Patent
Cryptographic apparatus and method
TL;DR: In this paper, a cryptographic system transmits a computationally secure cryptogram over an insecure communication channel without prearrangement of a cipher key, where the cipher key is generated by the conversers from transformations of exchanged transformed signals.
Journal ArticleDOI
Secure communications over insecure channels
TL;DR: This paper shows that it is possible to select a key over open communications channels in such a fashion that communications security can be maintained, and describes a method which forces any enemy to expend an amount of work which increases as the square of the work required of the two communicants to select the key.
Book
Secrecy, authentication, and public key systems
TL;DR: An automatic control system for a tube expander tool of the type having a hydraulically powered rotary tool which is advanced and retracted by a reversible linear motor to maintain a desired constant load and to prevent overloading.
