It mainly includes symmetric and asymmetric cryptographic algorithms and protocols. For the symmetric cryptographic algorithms, it is easy to deduce decryption keys from the encryption keys and vice versa. Because this algorithm encrypts and decrypts data very quickly, it is applicable in situations where large numbers of data have to be protected. However, for the asymmetric algorithm, extracting the secret key from the public key is computationally infeasible. Although the performance speed of the asymmetric algorithm is much slower than that of the symmetric algorithm, the asymmetric algorithm has key distribution and management advantages over the symmetric one. Moreover, it is a perfect digital signature scheme.展开更多

Adapted from the Norwegian model, the OBRSS awards individual academic staff using a points system based on the number of publications and doctoral students. This article describes the design and implementation processes of the OBRSS, including the creation of the ranked publication list and points system and infrastructure requirements. Some results of the OBRSS will be presented, focusing on the coverage of publications reported in the OBRSS ranked publication list and Scopus, as well as information about spending patterns. Challenges such as the evaluation of the OBRSS in terms of fairness, transparency, and effectiveness will also be discussed.展开更多

文摘Cryptography is an important technology for information security. It mainly includes symmetric and asymmetric cryptographic algorithms and protocols. For the symmetric cryptographic algorithms, it is easy to deduce decryption keys from the encryption keys and vice versa.
