Several Attentive Problems in the Application of RSA Public Key Algorithm
HE Cai-yan · Modern Computer · 2004
RSA algorithm is one of the most important algorithms in public key cryptosystem. According to the characteristic of RSA algorithm, several attentive problems are discussed on security of creating a pair of public-key and private- key in RSA algorithm. More attention should be paid to some blind spots during choosing a public-key. Ciphertext will be easily decrypted in case of its low power. It is unsafe when public modular is used in a group. New modular should be chosen to create new public-key and private-key after old private-key being lost.
