EN 1300:2013 (E) 12 Each HSL shall also incorporate a blocking feature or be capable of causing movement of a blocking feature. If this feature has to be activated before first use a note to this effect is to be included in the instructions for the use of the lock. 5.1.1.5 If the blocking feature is not moved manually there shall be a means of indicating whether the HSL has been secured, locked and scrambled. 5.1.1.6 An opening code shall not be capable of being altered or being changed other than by a recognized code. 5.1.2 Class D HSL 5.1.2.1 Means shall be provided by which the locking status, locked or unlocked, is made obvious. 5.1.2.2 A mechanical combination HSL shall be in a scrambled condition after locking. 5.1.2.3 A class D HSL shall contain a device which indicates the scrambled condition. 5.1.3 Mechanical Key Operated HSL 5.1.3.1 For class A HSL (see Clause 4), the same code shall not be repeated until at least 80 % of the usable codes have been used. 5.1.3.2 Codes (and sets of code tokens) shall be chosen at random. 5.1.3.3 There shall be no number or marking on either token or HSL which identifies the code. Also no legitimization card shall be issued. 5.1.3.4 It shall not be possible to remove the key from a HSL whilst that HSL is in the open position except for code changing. This requirement is applicable to all classes. Note that it is acceptable for this feature to be activated immediately prior to the first use of the HSL. 5.1.3.5 The key shall not break under the applied maximum torque of 2,5 Nm. The test is to be conducted according to 8.2.1.4. 5.1.3.6 In addition to the foregoing requirements the manufacturer is also to complete the declaration set out in Annex C. 5.1.4 Lift heights for mechanical key locks 5.1.4.1 Usable codes shall not have more than 40 % of the coding elements (levers) of the same lift height. 5.1.4.2 Usable codes shall not have more than two neighbouring elements, e.g. two levers next to each other, with the same lift height. 5.1.4.3 In usable codes, the difference between the highest and lowest lift height shall be more than 60 % of the maximum lift height difference of the HSL. 5.1.5 Electronic HSL 5.1.5.1 Electronic HSL as of class B and with more than 2 user codes shall retain the records of the opening events used according to Table 1 and shall have the means to retain the record for at least 1 year, even in the event of a power failure. 5.1.5.2 When the electronic HSL is secured further communication with the processing unit shall only be possible by inputting a recognized code and to display the lock status. SIST EN 1300:2014
EN 1300:2013 (E) 13 5.1.5.3 For non-distributed systems all component parts of the input unit shall be fixed to the secure storage unit. With the input unit being fixed to the secure storage unit the cabling from input unit to processing unit has to be non accessible. 5.1.5.4 In class C and D any manipulation or replacement of the input unit shall generate an audit entry and automatically display information to the user at each use until it’s neutralized by an authorized person. 5.1.5.5 If the Penalty Time is active there shall be a clear indication, in all classes of HSL, to the user. 5.1.5.6 Low Battery Indication: battery powered locks shall be able to operate for at least 3 000 complete lock openings. The battery capacity shall be monitored. In the case of a low battery/low batteries an audible or visual signal shall occur during or immediately after an opening process. After the first low battery signal at least ten (10) complete opening and locking processes shall still be possible. Where it is possible to connect power from the outside it will not be necessary to meet this requirement. 5.1.5.7 The processing unit for code evaluation shall be located inside the secure storage unit. 5.1.5.8 As of class B, electronic HSL have to be tested against influences by power supply according to 8.2.5. 5.1.6 Electronic tokens 5.1.6.1 General The manufacturer has to give a statement in his manuals that electronic tokens have to be secured as mechanical keys. 5.1.6.2 Contactless electronic tokens 5.1.6.2.1 General The following requirements for contactless electronic tokens are only applicable for near field communication devices, where a typical operation range is less than 15 cm, e.g. NFC or Mifare. If the typical distance between electronic token and input unit for data transmission is more than 15 cm or the electronic token is used for a class D HSL, the requirements of distributed systems as in 5.1.7 shall be met.
NOTE Optical systems are considered to be distributed systems. An example for a contactless electronic token is RFID card. 5.1.6.2.2 Mutual authentication Mutual authentication according to ISO/IEC 9798-2 or ISO/IEC 9798-4 shall be used. The time variant parameter such as time stamp, sequence numbers or random numbers to prevent valid authentication information from being accepted at a later time or more than once (see ISO/IEC 9798-1:2010, Annex B) shall have at least 32 bits. In addition to mutual authentication a valid opening code has to be used to open the HSL. 5.1.6.2.3 Cryptographic key The cryptographic key for symmetric algorithms shall have a minimum length of 64 bits for classes A and B and 128 bits for classes C and D and shall be intended only for the specific HSL model. Asymmetric algorithms shall have comparable key lengths with regard to the security level (NIST SP 800-57). The cryptographic key for symmetric algorithms or the private key for asymmetric algorithms shall never be sent out of the token. It may be part of the transmitted communication data into the electronic token for initialising purposes. The initialization process has to be done by an authorized person in a secure environment. This has to be stated in the user instructions. SIST EN 1300:2014
EN 1300:2013 (E) 14 5.1.6.2.4 Identification number Each electronic token shall have a unique identification number. The identification number shall have a length of at least 32 bits. Normally, the identification number is required for audit purposes only. If the serial number is also used as security relevant information, it shall not be visible on the token. 5.1.6.3 Contacted electronic tokens Contacted electronic tokens for locks other than class D do not have to meet the same additional requirements as contactless electronic tokens. The manufacturer then has to give a statement in his manuals if any security relevant information is stored unencrypted.
Security relevant information should be stored secure in the token and there should be a secure authentication. 5.1.6.4 Multi-use (only valid for class B, C and D) If the electronic token is designed to be used in applications other than the HSL system, the security relevant information shall not be accessible to the other applications. If the electronic token is not protected against multi-use, the following statement shall be included in the manual: Never use this electronic token in applications other than this HSL model. 5.1.7 Requirements for cryptography in distributed security systems 5.1.7.1 Information security 5.1.7.1.1 General This subclause focuses on confidentiality, authentication, integrity, availability, data transmission, information storage, cryptographic keys and their management. 5.1.7.1.2 Confidentiality
Security relevant information that is transmitted across a distributed system shall be encrypted to prevent unauthorized reading. For security relevant data transmission processes in distributed systems, symmetric algorithms such as TDEA 64 bit block and AES 128 bit block are the minimum requirements according to NIST SP 800-67 and FIPS 197 respectively. The encryption algorithm shall be used in a secure mode of operation such as CBC, CFB or GCM.
5.1.7.1.3 Authentication Authentication is required to start communication between devices of a distributed system. The authentication method has to be described by the manufacturer. 5.1.7.1.4 Integrity It shall be ensured that data has not been altered in an unauthorized manner since it was created, transmitted or stored. This includes the insertion, deletion and substitution of data. Accepted methods for ensuring integrity are MAC algorithms or digital signatures. 5.1.7.1.5 Availability If a distributed system is temporary not available this condition shall not compromise the level of security.
