On the security of multiple encryption

RC Merkle, ME Hellman - Communications of the ACM, 1981 - dl.acm.org
Abstract Double encryption has been suggested to strengthen the Federal Data Encryption
Standard (DES). A recent proposal suggests that using two 56-bit keys but enciphering 3
times (encrypt with a first key, decrypt with a second key, then encrypt with the first key ...

Dynamics of fluid flow inside carbon nanotubes

RE Tuzun, DW Noid, BG Sumpter, RC Merkle - Nanotechnology, 1996 - iopscience.iop.org
Abstract The dynamics of fluid flow through nanomachines is different from in other systems
in that the flow is granular (no continuum assumption) and that thewalls' move. We have
performed molecular dynamics simulations of the flow of helium and argon inside carbon ( ...

Reversible electronic logic using switches

RC Merkle - Nanotechnology, 1993 - iopscience.iop.org
Abstract Two methods of using switches to implement reversible computations are
discussed. The first method has an energy dissipation which is proportional to the square of
the error in the voltage, while the second method has an energy dissipation which can in ...

A fast software one-way hash function

RC Merkle - Journal of Cryptology, 1990 - Springer
Abstract One way hash functions are an important cryptographic primitive, and can be used
to solve a wide variety of problems involving authentication and integrity. It would be useful
to adopt a standard one-way hash function for use in a wide variety of systems throughout ...

Digital signature system and method based on a conventional encryption function

RC Merkle - US Patent 4,881,264, 1989 - Google Patents
A method of generating digital signatures for signing an infinitely expandable series of
messages Mi. An infinitely expandable tree of signature nodes is used, where each node
can be used to sign a message. Each node is also used to sign up to k subnodes, where k ...

Document copy authentication

RC Merkle, DS Bloomberg, JS Brown - US Patent 5,157,726, 1992 - Google Patents
A system for authenticating a hard copy of an original document. The system employs a
special copying machine at the sender's end together with a special ID card (smart card) or
other user identification for activating the special machine, and a special copying machine ...

Method and apparatus for data encryption

RC Merkle - US Patent 5,003,597, 1991 - Google Patents
A method and apparatus for encrypting and decrypting data which operates efficiently on
computers of differing architectures is disclosed. Unlike previous encryption/decryption
method and apparatus, the present invention executes efficiently in the computer's ...

Fast software encryption functions

RC Merkle - Conference on the Theory and Application of …, 1990 - Springer
Abstract Encryption hardware is not available on most computer systems in use today.
Despite this fact, there is no well accepted encryption function designed for software
implementation—instead, hardware designs are emulated in software and the resulting ...
