Abstract

Example embodiments of systems and methods for data transmission between a contactless card and a server are provided. The card may include an applet, a counter, and a plurality of encryption keys. The applet may rotate the plurality of keys based on a predetermined key rotation, select one or more keys for a cryptographic operation, perform the operation using the selected keys and the counter to generate a cryptographic result, and transmit the result and the counter to the server. Upon receipt of the result, a server, in communication with the card and containing the plurality of encryption keys, may rotate the plurality of keys based on the predetermined key rotation, select one or more keys for decryption, wherein the keys selected by the server matches the keys selected by the applet, and perform the decryption on the result.

Claims (38)

1 . A non-transitory computer-readable medium containing instructions for execution by a contactless card comprising a processor and a memory, the memory containing a plurality of keys, wherein, upon execution, the instructions configure the processor to perform procedures comprising:

rotating the plurality of keys based on a sequence interval after entry of the contactless card into a communication field;

selecting a selected key from the plurality of keys; and

performing a cryptographic operation using the selected key.

2 . The non-transitory computer-readable medium of claim 1 , wherein the sequence interval is based on a schedule of values.

3 . The non-transitory computer-readable medium of claim 1 , wherein the sequence interval is based on a temporal relationship.

4 . The non-transitory computer-readable medium of claim 3 , wherein the temporal relationship is based on a day of the week.

5 . The non-transitory computer-readable medium of claim 3 , wherein the temporal relationship is based on a month of the year.

6 . The non-transitory computer-readable medium of claim 3 , wherein the temporal relationship is based on at least one selected from the group of a date and a time.

7 . The non-transitory computer-readable medium of claim 1 , wherein the sequence interval is based on at least one selected from the group of a user and a user transaction history.

8 . The non-transitory computer-readable medium of claim 1 , wherein:

the sequence interval is based on a categorization of a user, and

the categorization of the user is based on at least one selected from the group of a frequency of transactions, a transaction history, and a risk.

9 . The non-transitory computer-readable medium of claim 1 , wherein the sequence interval is based on at least one selected from the group of a type of a transaction and a location of a transaction.

10 . The non-transitory computer-readable medium of claim 1 , wherein the sequence interval is based on a type of a merchant involved with a transaction.

11 . A contactless card, comprising:

a processor; and

a memory containing an applet and a plurality of keys,

wherein the applet is configured to:

rotate the plurality of keys based on a sequence interval after entry of the contactless card into a communication field;

select a selected key from the plurality of keys; and

perform a cryptographic operation using the selected key.

12 . The contactless card of claim 11 , wherein:

the communication field comprises a near field communication (NFC) field, and

the contactless card is powered by the NFC field.

13 . The contactless card of claim 11 , wherein the applet is further configured to rotate the plurality of keys in a random manner for a designated number of keys.

14 . The contactless card of claim 11 , wherein the applet is further configured to further rotate the plurality of keys based on a mapping table.

15 . The contactless card of claim 14 , wherein the mapping table includes a plurality of transactions associated with the plurality of keys.

16 . The contactless card of claim 15 , wherein each of the plurality of transactions is associated with a key of the plurality of keys.

17 . A method performed by a contactless card comprising a processor and a memory, the memory containing an applet and a plurality of keys, the method comprising:

rotating the plurality of keys based on a sequence interval after entry of the contactless card into a communication field;

selecting a selected key from the plurality of keys; and

performing a cryptographic operation using the selected key.

18 . The method of claim 17 , wherein the sequence interval is based on a temporal relationship.

19 . The method of claim 17 , wherein:

the sequence interval is based on a categorization of a user, and

the categorization of the user is based on at least one selected from the group of a frequency of transactions, a transaction history, and a risk.

20 . The method of claim 17 , wherein the sequence interval is based on a history of a user.
