RSA algorithm is a process of encrypting plain text in blocks, every block has a binary value lesser than some n number. The size of block should be less than log (n) or equal to log (n), public-key cryptosystem was implemented by RSA algorithm In this Journal we are going to ...

Another use case of RSA is to have a secure key exchange between two parties who have not previously shared a secret key. The two parties involved generate a public-private key pair using the RSA algorithm. The sender generates a symmetric key, encrypts it using the receiver’s public key...
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 ...
4)非对称加密算法(asymmetric cryptographic algorithm)又名“公开密钥加密算法”,非对称加密算法需要两个密钥:公开密钥(publickey)和私有密钥(privatekey)。公开密钥与私有密钥是一对,如果用公开密钥对数据进行加密,只有用对应的私有密钥才能解密;如果用私有密钥对数据进行加密,那么只有用对应的公开密钥才能解密。因为加密...
