In the last few decades, patients demand the data integrity and confidentiality of their Electrocardiography (ECG) signal for remote diagnosis through the network. In this context, a Dynamic Hash key‐based stream cipher for a cryptosystem is proposed to transmit the ECG signal to maintain integrity and confidentiality. The novelty of this proposed methodology is based on real‐time dynamic non‐recursive pseudorandom keystream using dynamic Toeplitz hash value‐based RC4 algorithm, unlike the existing static key‐based stream ciphers. The Toeplitz hash value (HV) is constructed from the sequence generated using non‐singular sequence folding‐based nonlinear feedback function expressed in algebraic normal form. The proposed design is realized using Verilog hardware description language (HDL) to construct the non‐recursive dynamic key stream sequence and prototyped on existing hardware Field‐programmable gate array (FPGA) device Virtex 5 xc5vlx110t‐2ff1136. The generated dynamic binary key stream sequence is analysed for key size, correlation and further verified by randomness tests using National Institute of Standards and Technology statistical test suites. The laboratory experiment is carried out with the existing two FPGA boards to prototype the proposed hardware cryptosystem for the encryption and decryption of real time ECG signal. The implementation result in the FPGA device accomplishes with the initial latency of 257 clock cycles and improved data throughput of 534Mbps than the existing design.

“…The keyed-hash message authentication code (HMAC) is scheme [15] used to achieve fault tolerance in the secure hash standard (SHS) and also reduces implementation area requirements and power consumption. The hardware implementation of the RC4 algorithm [16] based on dual-port block RAM in the FPGA in order to better utilize the available logic and memory resources, which achieves better performance. A high throughput digital design of the 128-bit advanced encryption standard (AES) algorithm [17] is based on the C-slow retiming, which provides design with feedback loops and automatically rebalances the registers in the design.…”

Now a day all the communications are carried out in wireless medium. It is necessary to transmit the confidential data in wireless media in secure manner. Cryptography is technique to protect electronic data in communication network. Hardware implementation of cryptography processor in field programmable gate array (FPGA) is major issues in terms of area, power and throughput. In this paper, we propose a hybrid crypto processor (HCP) for wireless network using flexible encryption and signature techniques. The main aim of proposed HCP technique used to provides secure wireless communication with aware of malicious attacks in the network, know to my knowledge, the proposed HCP hardware design is open the platform in signcryption. Generally, hybrid cryptography consists of data encapsulation mechanism (DEM) and key encapsulation mechanism (KEM). In HCP design, the efficient multiplier based ECC processor is proposed for data encapsulation over Galois field (GF (2 m )). Moreover, the improved enhanced Kurosawa and Desmedt hashing (EKD) hashing scheme is proposed for key encapsulation. The proposed HCP design is implementing in Xilinx tool with different field programmable gate array (FPGA) families. The result shows that effectiveness of proposed HCP design in terms of hardware utilization, power consumption and throughput over existing design.

“…Moreover, it has the higher speed and the lower complexity than other stream ciphers. The data of statistics show that the RC4 algorithm is used to protect 50% of TLS traffic as the most widely used secure communication protocol on the internet nowadays [21]. RC4 has a secret internal state and works by generating the pseudorandom stream of bits [22].…”

Messages sent using the default Short Message Service (SMS) application have to pass the SMS Center (SMSC) to record the communication between the sender and recipient. Therefore, the message security is not guaranteed because it may read by irresponsible people. This research proposes the RC4 stream cipher method for security in sending SMS. However, RC4 has any limitation in the Key Scheduling Algorithm (KSA) and Pseudo Random Generation Algorithm (PRGA) phases. Therefore, this research developed RC4 with a random initial state to increase the randomness level of the keystream. This SMS cryptography method applied the processes of encryption against the sent SMS followed by decryption against the received SMS. The performance of the proposed method is evaluated based on the time of encryption and decryption as well as the average correlation value. Based on the time, it shows that the length of the SMS characters sent affects the time of encryption and decryption. Meanwhile, the best correlation value achieved 0.00482.
