它是基于SAFER系列算法提出的，因此，它的安全性可以说是经过了时间的考验。另外，SAFER+算法中仅仅用了字节运算，并且所需要的内存很小，因此，在Smart卡等方面的应用是很有优势的。SAFER+算法是一个代换/线性变换密码，它的加/解密过程并不相似。-It is based on the SAFER family of algorithms proposed, therefore, its security can be said that after the test of time. In addition, SAFER+ Algorithm just a little bit computing, and the required memory is very small, therefore, in the areas of Smart Card applications is very advantage. SAFER+ Algorithm is a substitution/linear transformation password, its encryption/decryption process is not similar.
