Abstract: Recently,RSA encryption algorithm is a widely used asymmetric encryption algorithm with high security.Mathematic basis of RSA encryption algorithm which belongs to asymmetric encryption system is analyzed.Possible methods to decrypt it are discussed as well.Then,according to recent running speed of computer,time for decryption by using a normal length of key is calculated.Besides,quantitative analysis of security of RSA algorithm is implemented.

Key words: RSA, data encryption, data security, key decryption
