Abstract
In one implementation, a method for providing access to a secure facility includes authenticating the user; generating a card credential, transmitting the card credential to an access card carried by of the user, and transmitting the card key to the access card in a form that is usable by the access card. The generating the card credential includes encrypting the card key using a server encryption key. The card key is usable for a challenge-response interaction during subsequent access requests by the user.
Claims15
A method comprising:
- generating, using a processor, a card credential, wherein
- the generating the card credential comprises encrypting a card key using a server encryption key;
- transmitting the card credential to an access card, wherein
- the access card is configured to transmit the card credential in an authentication interaction.
3-19. (canceled)
A system comprising:
- a data interface;
- a memory;
- and
- a processor coupled to the data interface and the memory, and configured to
- generate a card credential into which the card key has been locked using an encryption key stored in the memory;
- and
- transmit the card credential to an access card through the data interface, wherein
- the access card is configured to transmit the card credential in an authentication interaction.
24-26. (canceled)
A system comprising:
- means for generating a card credential, wherein
- the means for generating the card credential comprises means for encrypting a card key using a server encryption key;
- means for transmitting the card credential to an access card, wherein
- the access card is configured to transmit the card credential in an authentication interaction.
(canceled)
A non-transient computer-readable medium having encoded thereon instruction executable by one or more processors to perform acts comprising:
- generating a card credential, wherein
- the generating the card credential comprises encrypting a card key using a server encryption key;
- transmitting the card credential to an access card, wherein
- the access card is configured to transmit the card credential in an authentication interaction.
