Datang Telecom Social Security Dedicated Chip DMT-CTSB16A5

Datang telecommunication is the main supplier of domestic social security chip. We have developed the social dedicated chip DMT-CTSB16A5 with wholly owned IPRs, it fully accords with the social security (personal) card standard. This product can support general DES/3DES symmetric algorithms, RSA unsymmetric algorithms and SSF33,SM1 encryption algorithm of National security office, it can realize electronic credential, information storage, information query, electronic purse, and other functions. We believe our chip can meet the needs of different users.
DMT-CTSB16A5 design between speed, safety, area, power and other factors, it is a large capacity, high speed, high security, high stability, lower consumption smart-card chip.
