Did not used Viaccess SmartCard with Sbox but if you read sbox.conf this is what you find:
#Viaccess Example
[CCCCCCCC] # via camid (4 bytes)
emm=7 # 0=accept all 1=block emms 2=block emmu 4=block emmg
portlist=0 # use portlist or no
portlistpath= # path from port.list
aeskey= # aeskey used by nano d2
