Frequently Asked Question - Do your cards support A3/A8 algorithm?

Do your cards support A3/A8 algorithm?

Our cards do support A3/A8 implementation of algorithms, but just to be clear, A3/A8 is not an algorithm per se, but the requirements to implement an A3 or A8 algorithm. So please ask for the specific algorithm you need.

See definition from standard below:

A3 Algorithm is used to encrypt Global System for Mobile Communications (GSM) cellular communications. In practice, A3 and A8 algorithms are generally implemented together (known as A3/A8). An A3/A8 algorithm is implemented in Subscriber Identity Module (SIM) cards and in GSM network Authentication Centres. It is used to authenticate the customer and generate a key for encrypting voice and data traffic, as defined in 3GPP TS 43.020 (03.20 before Rel-4). Development of A3 and A8 algorithms is considered a matter for individual GSM network operators, although example implementations are available.
