The invention discloses a quick detection method for code achievement side channel safety. The method comprises the steps that 1 a function CDF of an actual leak value vector L is calculated, and a dictionary Dic is subscripted; 2 for each plaintext, hypothetic energy consumption p corresponding to each secret key guessing value k and the plaintext is calculated, and according to the value p and the value k, a sequence number of the plaintext is classified to the k + 1 line and the p + 1 row of a subscript group G; 3 for each secret key guessing value k, subscript grouping elements of a nonblank actual leak value energy trace of gathering assumption energy consumption is extracted from the G, then a vector is combined according to the actual leak value, a corresponding function CDFt is calculated according to the Dic, and then the score of the k is determined according to the assumption probability corresponding to the maximum difference between the CDF and the CDFt; 4 the value k corresponding to the minimum value of the score is compared with a secret key byte numerical value of an encryption algorithm, and whether the encryption algorithm achieved on equipment is safe is judged. According to the quick detection method, the achieving safety of the detected encryption algorithm on the equipment can be detected quickly.
