An implementation for a fast public-key cryptosystem 总被引:9,自引:0,他引:9
In this paper we examine the development of a high-speed implementation of a system to perform exponentiation in fields of the form GF(2
n
). For sufficiently large n, this device has applications in public-key cryptography. The selection of representation and observations on the structure of multiplication have led to the development of an architecture which is of low complexity and high speed. A VLSI implementation has being fabricated with measured throughput for exponentiation for cryptographic purposes of approximately 300 kilobits per second. 相似文献

A theory is developed for the construction of carry-save networks with minimal delay, using a given collection of carry-save adders each of which may receive inputs and produce outputs using several different representation standards.The construction of some new carry-save adders is described. Using these carry-save adders optimally, as prescribed by the above theory, we get {, , }-circuits of depth 3.48 log2
n and {, , }-circuits of depth 4.95 log2
n for the carry-save addition ofn numbers of arbitrary length. As a consequence we get multiplication circuits of the same depth. These circuits put out two numbers whose sum is the result of the multiplication. If a single output number is required then the depth of the multiplication circuits increases respectively to 4.48 log2
n and 5.95 log2
n.We also get {, , }-formulae of sizeO (n
3.13) and {, }-formulae of sizeO (n
4.57) for all the output bits of a carry-save addition ofn numbers. As a consequence we get formulae of the same size for the majority function and many other symmetric Boolean functions. 相似文献

Precoding for transmission over channels with interference known at the transmitter is reviewed. In contrast to what is usually discussed in literature, precoding employing higher-dimensional lattice quantization for generating the transmit signal is assessed. It is shown that thereby the gap between low-complexity schemes using scalar modulo reductions and theoretical asymptotic results assuming hypothetical optimum quantization operations can be bridged. In this paper, capacity curves obtained from numerical calculations, and approximations to the capacity are provided for various lattices. Moreover, the role of appropriate scaling at transmitter and receiver is discussed in detail. 相似文献

We discuss new algorithms for multiplying points on elliptic curves defined over small finite fields of characteristic two.
This algorithm is an extension of previous results by Koblitz, Meier, and Staffelbach. Experimental results show that the
new methods can give a running time improvement of up to 50 % compared with the ordinary binary algorithm for multiplication.
Finally, we present a table of elliptic curves, which are well suited for elliptic curve public key cryptosystems, and for
which the new algorithm can be used.
