Commission Implementing Regulation (EU) 2016/799Show full title

Commission Implementing Regulation (EU) 2016/799 of 18 March 2016 implementing Regulation (EU) No 165/2014 of the European Parliament and of the Council laying down the requirements for the construction, testing, installation, operation and repair of tachographs and their components (Text with EEA relevance)

CSM_133Vehicle unit manufacturers shall insert only one set of VU-specific DSRC keys into each vehicle unit, together with its version number. This set of keys shall be derived from the KM_DSRC generation linked to the ERCA certificate upon which the VU's certificates are based.U.K.

Notes: U.K.

—This implies that a vehicle unit based on the generation X ERCA certificate shall only contain the generation X K_VU_DSRC_ENC and K_VU_DSRC_MAC_, even if the VU is issued after the start of the validity period of the generation X+1 ERCA certificate. This is shown in Figure 3.U.K.

—Since workshop cards have a validity period of one year and control cards of two years, the result of CSM_131 — CSM_133 is that all workshop cards and control cards will contain the new DSRC master key at the moment the first VU containing VU-specific keys based on that master key will be issued.U.K.
