CPU card chip development trends in substitute for logic encrypt card chip

Currently on the market is the most common non-contact IC card contactless logic encryption card, this type of IC card due to their high performance and high value for customers of all ages, and has been widely used in public transportation, health care, campus card, access control and other fields. Due to the non-contact logic encrypt card chip technology is used in stream ciphers, the key length is not very long (typical length of password is Mifare 48 bit), so logic encrypt card chips there are certain security risks, have the potential to be cracked by hackers. In finance, identification, electronic passports, has high security requirements field is now more inclined to use contactless CPU card chip embedded microprocessors.
