RSA is a widely used cryptographic algorithm that was first introduced in 1977. It uses public and private key pairs to encrypt and decrypt data. Though RSA can be used in several applications, its computational complexity makes it unsuitable for encrypting large messages or files. Currently, RSA...
摘要: We deal with the RSA encryption algorithm. Its safety is analyzed using the number field sieve method. The algorithm work results allow to define a secret key in a simple way关键词: computational complexity computer networks cryptography RSA encryption algorithm computational complexity computer ...
RSA Encryption Algorithm in a Nut Shell. 5 Chapter Two Mathematical Background Big Oh notation A function f (n)=O(g(n) ) or f=O(g), if there exists constants c,n0such that f(n)= n0Figure 1, as below shows the growth of functions f(n) and g(n). For n>=n0 展开 ...
The RSA algorithm is used by modern devices to encrypt/decrypt messages. It uses asymmetric cryptography, meaning that it use two different keys: public and private key. The public key is known to everyone in the party, whereas the private key is only known to either the sender or the rece...
Observe that no private transactions between Alice and Bob are needed to estab-lish private communication. The only “setup” required is that each user who wishesto receive private communications must place his enciphering algorithm in the publicfile. ...

Chinese remainder theorem based RSA (CRT-RSA) digital signature has important applications in smart cards. Previous CRT-RSA algorithms such as CRT-2 and BOS are susceptible to practical hardware fault attacks. In this paper, a new CRT-RSA algorithm with countermeasures to hardware fault attacks is...
An efficient RNS base, 2 n − c i , is chosen to reduce the multiplication complexity of RNSMM. Experimental results show that the proposed processor has better tradeoff among algorithm flexibility, performance and area than other related works. 展开 ...
The longer the key pair, the harder it is to crack, and the more secure but slow the encryption algorithm. It is recommended that the number of bits of the RSA key pair exceed 2048; otherwise, it has security risks. Example # Create an RSA key pair rsakey. <HUAWEI> system-view [...
