3.2.21. AT#ENCALG - Set Encryption Algorithm
This command enables or disables the GSM and/or GPRS encryption algorithms supported by the module.
AT#ENCALG=[<encGSM>][,<encGPRS]
Set command enables or disables the GSM and/or GPRS encryption algorithms supported by the
module.
Parameters:
The <encGSM> (one byte long) is a bit mask where each
bit, when set, indicates the corresponding GSM encryption
algorithm
• bit 0 = A5/1
• bit 1 = A5/2
• bit 2 = A5/3
• bits 3 - 7 = reserved for future use
no GSM encryption algorithm
sum of integers each representing a specific GSM encryption
algorithm: 1 – A5/1 2 – A5/2 4 – A5/3
The <encGPRS> (one byte long) is a bit mask where each
bit, when set, indicates the corresponding GPRS encryption
algorithm
• bit 0 = GEA1
• bit 1 = GEA2
• bit 2 = GEA3
• bits 3 - 7 = reserved for future use
no GPRS encryption algorithm
sum of integers each representing a specific GPRS encryption
algorithm: 1 – GEA1 2 – GEA2 4 – GEA3
The values are stored in NVM and available on following reboot.
For possible <encGSM> and <encGPRS> encryptions see test command response.
If no parameter is issued, the set command returns ERROR.
