Implementation and optimization of a data protecting model on the Sunway TaihuLight supercomputer with heterogeneous many‐core processors

Abstract

With the rapid development of information technology, the security of massive amounts of digital data has attracted huge attention in recent years. The Advanced Encryption Standard (AES) algorithm and the Security Hash Algorithm 3 (SHA3) are extensively used as cryptographic algorithms for protecting the security of information. The Sunway TaihuLight, with massive heterogeneous many-core SW26010 processors, has the peak performance of over 100 PFlops. To achieve high efficiency of data encryption/decryption and guarantee the data integrity for large-scale applications, this paper proposes a fast and secure data protecting model using the parallel AES algorithm and the SHA3 on the Sunway TaihuLight. According to the particular computing architecture and memory hierarchy of the Sunway TaihuLight, we propose a fine-grained software design for the data protecting model to fully exploit the parallelism and properly arranges the data on the Sunway. Furthermore, we propose optimization strategies for the parallel AES algorithm of the data protecting model. It is proved that our data protecting model has high security, good scalability, and excellent encryption/decryption efficiency on the Sunway. Our data protecting model achieves a high throughput of 269.95 Gbits/s, and the optimized parallel AES algorithm achieves 511.28 Gbits/s on the Sunway.

Large amount of digital data is generated and stored in the internet. As the activity of internet users progressively increases, we are faced with the risk of security and confidentiality of massive digital information. In addition, the growing number of incidences of data leakage leads serious impact and losses to the internet users, which makes the data security become the hot point and a major concern of the society. It is extremely urgent to figure out a way to provide a reliable and safe environment for internet users.Using the cryptographical technology is one of the key methods to ensure the security of digital data. In cryptography, the block cipher has strong applicability and security. It executes encryption and decryption on a set of fixed-size data blocks using a symmetric key. The Advanced Encryption Standard (AES) 1 is a block cipher extensively used by enterprises and organizations for protecting the security of information. However, the traditional AES encryption/decryption is a computationally intensive task, which leads to the inefficiency of encrypting/decrypting large-scale digital data. In addition, the traditional AES algorithm is unable to meet the demand of protecting massive data efficiently. Users cannot accept too much time spent on data encryption/decryption. Normally, the AES algorithm takes a 16-byte data block as input and performs several rounds o...

“…There are a few early development experiences on Sunway TaihuLight supercomputer. Chen et al 34 designing and implementing a parallel AES algorithm, and the result shows that the parallel AES algorithm achieved a good speed-up performance. Fang et al 35 have implemented and optimized a library, namely swDNN, which that supports efficient deep neural networks (DNNs) implementation on Sunway TaihuLight supercomputer.…”
