The invention discloses a cryptographic machine key attribute test method, which comprises the following steps that a cryptographic machine imports a first index, a key and a first key attribute according to a key import instruction sent by test equipment; after importing succeeds, the test equipment sends a next secret key importing instruction, the first index is an index initial value + 1, andthe first secret key attribute is a secret key attribute initial value + 1; the above steps are repeated until all to-be-imported first indexes are imported; the cryptographic machine carries out calculation according to the secret key corresponding to the second index to be verified in the verification instruction and the operation function information to be verified, and the test equipment carries out verification according to the calculated first result, judges whether the secret key corresponding to the second index has the operation function or not and records the secret key in the secondsecret key attribute corresponding to the second index. The cryptographic machine key attribute test method provided by the invention is simple in test process and convenient for statistics, and improves the test comprehensiveness, test quality and flexibility.
