摘要:
A data processing device, in a system performing authentication among a plurality of storage device (IC cards etc.), able to maintain security of authentication at other device even when secrecy of key data held by part of the devices is lost, wherein a key generation unit generates individual key data unique to an IC card based on identification data unique to the IC cards received from the ICs of the IC cards and a card processing unit performs mutual authentication with the IC based on the individual key data.

摘要:
A data processing apparatus is provided which is capable of improving the responsiveness of communication in which only a maximum of one access request source has write authorization and the other access requests do not have write authorization when communication is performed with a plurality of access request sources. A management apparatus transmits, to a secure application module (SAM), a strong connection request requesting the obtainment of write authorization into the SAM. When it is determined that the strong connection has not already been assigned to the other management apparatuses, the SAM assigns the strong connection to the management apparatus in a state in which a weak connection having read authorization with the management apparatuses is maintained.
摘要:
A data processing device able to keep a technique for generation of the key data in a key generating means secret from a developer of an authenticating means, wherein an authentication program has a description for calling up a function in a key generation program and entering identification data of service etc. input from an IC of an IC card as input parameters of the function and wherein a key generation program generates a key by using the identification data written at predetermined addresses as input parameters in accordance with the execution of a code on the basis of the authentication program.

摘要:
An information processing apparatus for using key information calculated on the basis of predetermined information including information obtained from an IC chip as a communication party on the other end in order to perform encryption processing with the IC chip. The information processing apparatus includes: among a plurality of calculation modules for calculating the key information being individually different in accordance with predetermined algorithms, control means for causing the calculation module identified by identification information input from the outside to calculate the key information; and encryption means for encrypting data by the key information calculated.
摘要:
An encryption apparatus capable of effectively preventing encryption data from being illegally generated is provided. Based on apparatus identification data of an integrated circuit (IC), which is input from a computer, a secure application module (SAM) selects an encryption method from among a plurality of different encryption methods. Based on the code of the IC, the SAM selects plaintext data to be encrypted from among the plurality of different pieces of plaintext data. The SAM outputs encryption data such that the selected plaintext data is encrypted by the selected encryption method.
