General Description
The SEC-31 Financial Data Encryptor is a reliable encryption device designed to protect transactions in financial networks. The device secures data transfer by perform data encryption, message integrity verification and key management, preventing financial fraud on networks. The SEC-31 is in use in many banks, social security service, taxation and security exchange systems.

Applications
l   Internal transaction clearance within one bank or between different banks or financial organizations.
l  The IC card application systems for mobile bank, social security and taxation.
l   Cross-organization financial exchange system.
l  Cryptosystem Supports symmetrical and asymmetrical cipher mechanism Supports DES and 3DES Supports RSA

Supports hash algorithm SHAI, MD5

Features
l   PIN Verification and transfer
l   Message Authentication Code(MAC) and Transfer Authentication Code
l   Translation between a DES algorithm and special financial cryptographic algorithm
l   Digital signature/verification
l  Key generation, distribution, backup and refreshing
l  Algorithm Support Proprietary algorithm for financial industry DES and triple DES algorithm RSA algorithm Support HASH algorithm SHAI and MD5 Customer algorithm 
l  Standard compliance  ANSI X.3.92 data encryption algorithm ANSI X9.9 message authentication ANSI X9.8 management and security of PIN  ANSI X9.17 key management ANSI X9.19 authentication of retail sales financial data Supports the user cipher code format of a multitude of ATM Compatible with the secure application standard of international credit card
l  Security Tamper resistance design Automatically destroys key when tampered Manual key destroying Password based key management and user right control The key that stored outside the encryptor is segmented and stored in ciphertext
