BSC ConclusionContents:


Generates an RSA private/public key pair

Stores an RSA public or private key

Retrieves the RSA Public key

Stores or retrieves an X.509 certificate

Sets a host challenge with the private RSA key

BSC Token

Similarities with SMC

– Depends on the smart card chip

– Platform environment (MAF based)

– User Authentication (C-R protocol)

Differences

– Bluetooth channel is used

– PIN entry done at BSC Token

SMC BSCContents:


Many mobile devices such as are being in the today’s

market. Still they are providing important contentencryption , virus protection , etc. which increases theeffort required to compromise a device. With the help of this approach user can able to select different levels of security to make the information as secure as possible.

Conclusion

• Heavily Used PDAs lack in security features suchas user authentication, etc

• MAF provides multiple mode of authentication
