![]() Thanks to utilization of both methods we were able to save a significant portion of hardware resources with a relatively small penalty in terms of performance. This system uses efficiently hardware-software co-design and partial reconfiguration techniques. The proposed solution supports the three main IPSec protocols: Encapsulating Security Payload (ESP), Authentication Header (AH) and Internet Key Exchange (IKE). In this paper we present a practical low-end embedded system solution for Internet Protocol Security (IPSec) implemented on the smallest Xilinx Field Programmable Gate Array (FPGA) device in the Virtex 4 family. In addition, the effectiveness of the architecture in terms of network delay and network load is verified. The experimental and analysis results show that the computing architecture designed in this paper has high network encryption performance and can effectively prevent data leakage. Finally, pipeline technology and critical path optimization on FPGA are used to parallelize the underlying encryption algorithm and data compression algorithm to achieve high-speed memory communication and meet the performance requirements of different networks. If an abnormality is found, different disturbance factors are activated using key management to change the system running status and restore the stability of the system. Secondly, based on the principles of dynamization, diversification, and randomization, the initial random key is generated using a pseudo-random number generator and a scrambling factor, and the hash of the data packet value updates the key to ensure “one frame, one key.” Then, an ARM microprocessor is used to monitor the working status of the system in real-time. Firstly, the access control lists are set through FPGA to authorize and filter illegal data, thereby reducing the transmission and processing of invalid data on the network. To strengthen the security of edge network data and reduce network latency, in this paper, we combine an advanced reduced instruction set computing machine (ARM) and a field programmable gate array (FPGA) to propose a lightweight ARM-FPGA computing architecture for edge network data security protection and acceleration. The implementation's performance can be easily improved by incorporating additional key generation units. The initial FPGA implementation incorporates four password-derived encryption key generation units operating at a frequency of 150 MHz and is capable of processing over 510 passwords per second. This is the most computationally demanding step required when performing a dictionary attack on modern password-protected systems. This paper describes an FPGA-based hardware implementation of the standard CPSK#5 technique published by RSA Laboratories for generating password-derived encryption keys. In order to improve throughput, forensic analysis tools are designed to operate in a distributed manner over a dedicated network of workstations. Such techniques impose a significant computational burden on forensic tools that attempt dictionary attacks are requiring cryptographic hash generation functions to be called several thousand times for each password attempted. Operating systems and data protection tools are employing sophisticated password derived encryption key techniques in order to encrypt data. The proposed implementation achievedĪ throughput that exceeded 2,5 Gbps, which is the highest among all similar IP cores for the targeted XILINX technology. The implementation’s characteristics are compared to alternative implementations proposedīy the academia and the industry, which are available in the international IP market. The proposed SHA-1 hash function was prototyped and Operational block of SHA-1 is modified so that maximum operation frequency is increased by 30% approximately with negligibleĪrea penalty compared to other academic and commercial implementations. Exploiting the information dependencies, the fundamental Temporal values in parallel to the calculation of other independent values. This allows pre-computation of intermediate Of the SHA-1 expression to separate information dependencies and independencies. Value in four discreet stages, corresponding to the four required rounds of the algorithm. Pipeline allows division of the calculation of the hash Of execution through pre-computation of intermediate temporal values. The proposed architecture exploits the benefits of pipeline and re-timing ![]() The Secure Hash Algorithm 1 (SHA-1) is proposed. In this paper, a novel FPGA implementation of Such as Internet Protocol Security (IPSec) and Virtual Private Network (VPN). Implementations of these functions are cryptographic primitives widely used in common cryptographic schemes and security protocols Hash functions are special cryptographic algorithms, which are applied wherever message integrity and authentication are critical.
