Viaccess

Viaccess is a conditional access system developed by Orange S.A.. There are six versions in use today, Viaccess PC2.3, Viaccess PC2.4, Viaccess PC2.5, Viaccess PC2.6, Viaccess PC3.0, Viaccess PC4.0, Viaccess PC5.0, and Viaccess PC6.0. Viaccess was developed as the digital version of the EuroCrypt system used with the hybrid MAC system, The first version is sometimes referred to as Viaccess 1, and the latter three, although different, as Viaccess 2. PC2.3 and PC2.4 are known to be ineffective, and many set-top boxes can be 'patched' to decrypt Viaccess signals without payment, however PC2.5 and PC2.6 are secure, with PC2.5 remaining secure two years after its first commercial deployment. PC2.6 was introduced at the end of 2005. PC3.0 was introduced during mid-2007. There are two modifications of Viaccess PC2.3 in use. The first, known as TPS Crypt, is used by TPS. Despite being compromised also, the TPS Crypt system has been further modified to utilise Advanced Encryption System keys.
