CENTRALISED CRYPTOGRAPHIC SYSTEM AND METHOD WITH HIGH CRYPTOGRAPHIC RATE.
Application IN/PCT/2002/00426/MUM published 2006-05-05, filed 2002-04-05
In a system of distributed services such as pay television, the data exchanged between a management centre and user modules use cryptographic means to guarantee authenticity and confidentiality of data. The requirements for cryptographic processing in the management centre are important; hence the invention concerns a cryptographic system combining modularity and security, for the cryptographic operations, of monolithic security units such as smart cards.
