p rtic lar, this tec nical re ort:

ex han e b twe n s bstation an control or maintenan e centres

• des rib s the u age of the con g ration lan uage of IEC 618 0-6

• gives g idel nes for the selection of commu ication services an arc itectures

• des rib s the l n s regardin the Sp cifi Commu ication Service Ma pin (SCSM)

This tec nical re ort do s not def i e con traints or l mitation f or sp cifi device

sec rity thre ts an sec rity fun tion fou d in IEC TS 6 3 1-1 an IEC TS 6 3 1-2 This

tec nical re ort tou hes several sec rity asp cts with the f ol owin b sic as umption :

• Inf ormation authentication an integrity (e.g the a i ty to provide tamp r detection) is

ne ded

• Con dential ty is o tional

It s al b p s ible to provide information authentication an integrity in an en -to-en

method, regardles of inf ormation hierarc ies The typical method to provide this sec rity

f un tion is throu h some typ of inf ormation/mes age authentication code IEC 6 3 1-4:2 0

a pl cation whic deman information from the s bstation or p rf orm control fun tion in the

s bstation Sup ortin fun tion are e.g the tran f er of disturb n e record an the c an in

5.9.1.2 Logic l al oc tion of f unction a d interf ac s

The fun tion of a s bstation automation s stem may b alocated logical y on thre dif ferent

levels (station, b y/u it, or proces ) These levels are s own by the logical interpretation of

Fig re 1 together with the logical interf aces 1 to 1
