Low Latency FPGA Implementation of Twisted Edward Curve Cryptography Hardware Accelerator over Prime Field

The performance of any elliptic curve cryptography hardware accelerator significantly relies on the efficiency of the underlying point multiplication PM architecture. This article presents a hardware implementation of field-programmable gate array FPGA based modular arithmetic, group operation, a...

`VMABuffer::set_data` may allow out-of-bounds writes from safe code

VMABuffer::setdata was a publicly accessible safe function. It accepted an arbitrary offset and a data slice, then used the offset in unsafe pointer arithmetic before copying the slice into a mapped allocation. Affected versions did not check that the requested write range fit within the allocati...

Extending the ElGamal Cryptosystem to the Third Group of Units of $\Z_{N}$

In this paper, we extend the ElGamal cryptosystem to the third group of units of the ring $\Zn$, which we prove to be more secure than the previous extensions. We describe the arithmetic needed in the new setting. We also provide some numerical simulations that shows the security and efficiency o...
