Composite field multiplier based on look-up table for elliptic curve cryptography implementation

In this work we propose the use of composite field to implement finite field multiplication, which will be use in ECC implementation. We use 299-bit keylength and GF((213)23) is used instead of GF(2299). Composite field multiplier can be implemented using conventional multiplication operation or using LUT (Look-Up Table). In this paper, LUT is used for multiplication in ground field and Karatsuba Offman Algorithm for the extension field multiplication. A generic architecture for the multiplier is presented. Implementation is done with VHDL with the target device Altera DE -2.

Realization and Addressing Analysis In Blockchain Bitcoin

The implementation research and analyze address blockchain on this bitcoin will have the results that refers to making address bitcoin a safe and boost security of address the bitcoin. The working mechanism of blockchain in making address bitcoin which is already in the blockchain system.

Implementation and Analysis of the use of the Blockchain Transactions on the Workings of the Bitcoin

The present study discusses the workings of blockchain bitcoin in the transactions sector, on the development of todays emerging computers in the financial sector of blockchain bitcoin traction. In this case the author analyzes how the transaction is running, as well as how blockchain bitcoin is doing work in transactions on the system to make transactions. Transaction is a data structure that encodes the transfer of values between users with in a bitcoin system. Every transaction is a public entry in this bitcoin blockchain. And become a large transaction bookkeeping global.

Information Concealment Through Noise Addition

Abstract A novel method of concealing information is proposed. Encrypted data is mixed with noise to add the security. The cost of an attack increases linearly with the size of the added noise. Since generating noise is cheap, the size of noise can be as large as possible. However, there are issues in automatically detecting and separating noise in the intended recipient end. This stegocrypto method also provides protection from traffic analysis attack.
