p位 meaning in Chinese

p-site

Under the condition of the precision of p bits and regardless of the absolute value less than , the space of initial key is about , the entropy of system is about ( 5p + 20 ) / 6 , which comes up to the demand of the security at the sense of modern cryptology
同时，初始密钥也具有很高的强度，采用p位精度且不考虑绝对值小于的值时，初始密钥空间的大小k约为，系统的熵h ( k )约为( 5p + 20 ) / 6 ，完全符合现代密码学意义下的安全性要求。
