MIFARE1 card and CPU Carter comparison <br> <br> for the CPU card, it makes up for the many shortcomings MIFARE1, it MIFARE1 card CPU card so what is the difference and what advantages do the following brief introduction??:
(1). The storage space and partition MIFARE1 card storage space is very limited, and it adopts fixed sector and block management.
The memory space of the CPU card is several times that of the MIFARE1 card, which fully meets the current storage needs. The file storage method is similar to the operating system, and the design is very flexible.
(b). The key length MIFARE1 card uses a 6-byte password and is sector controlled.
The CPU card uses 16-byte keys, and can establish multi-level partitions according to actual needs to achieve multi-level partitioned multi-level key combination control and improve the use of security.
(C). The encryption authentication algorithm MIFARE1 card uses a dedicated undisclosed hardware logic algorithm, which has been cracked.
The CPU card uses a common open software or hardware acceleration algorithm, can be customized, and meets financial standards.
(IV). The read-write security module MIFARE1 card uses an algorithm built-in key delivery. The authentication method is card and private base station chip authentication. This technology has been cracked.
The CPU card adopts the universal read-write module to transmit transparently. With the SAM key algorithm, the authentication is performed inside the two cards, and the encrypted random number is used in the transmission process, which greatly improves the security during reading and writing.
(E). Trading Process MIFARE1 card transaction process is simple and non-standard, requiring custom defense process.
The CPU card has the financial standard specification and can also be designed flexibly by the user.
(6). Access Control MIFARE1 cards can be read-only, write-only, read-write, plus or minus.
The CPU card can flexibly design the authentication method for different file types.
(VII). Advantages of the CPU Card From the perspective of system security, the IC card is also continuously improving in terms of security. The CPU card is the most prosperous of its vitality in terms of security. The CPU card can use a variety of security methods, and can even play a role in protecting the software system. Many different applications can be used at the same time, such as the storage structure of a virtual MIFARE1 card, ie one card for multiple uses. The combined use of COS and software systems improves operational flexibility.
