Abstract
A Digital Transaction Processing Unit (DTPU) operable to host one or more transaction applications for digitally transacting with a Digital Transaction Device (DTD), the DTPU including a security hierarchy for hosting the one or more transaction applications, wherein the security hierarchy is configured to host at least one transaction application for transacting in contact digital transactions.
Claims13
A Digital Transaction Processing Unit (DTPU) hosting one or more transaction applications for digitally transacting with a Digital Transaction Device (DTD), the DTPU comprising a security hierarchy having one or more security domains, each security domain hosting at least one of the one or more transaction applications, the one or more transaction applications comprising at least one of:
- a transaction application for transacting in contact digital transactions,
- a transaction application for transacting in contactless digital transactions, or
- a transaction application for transacting in both contactless and contact digital transactions
- wherein each security domain comprises a reversable locking process by which, when the security domain is reversibly locked, the one or more transaction applications hosted by the security domain are reversibly locked so as to be inoperable during a digital transaction and cannot be directly selected by a DTD,
- wherein the security hierarchy further comprises lock Supplementary Security Domain (lock SSD) to provide a cascade locking process by which one or more of the security domains in the security hierarchy are reversibly locked when the lock SSD is reversibly locked.
In a Digital Transaction Processing Unit (DTPU) hosting one or more transaction applications for digitally transacting with a Digital Transaction Device (DTD), the DTPU including comprising a security hierarchy for having one or more security domains, each security domain hosting at least one of the one or more transaction applications, wherein the security hierarchy is configured to host at least one the one or more transaction applications comprising at least one of:
- a transaction application for transacting in contact digital transactions,
- a transaction application for transacting in contactless digital transactions, or
- a transaction application for transacting in both contactless and contact digital transactions
- wherein each security domain comprises a reversable locking process by which, when the security domain is reversibly locked, the one or more transaction applications hosted by the security domain are reversibly locked so as to be inoperable during a digital transaction and cannot be directly selected by a DTD,
- wherein the security hierarchy further comprises lock Supplementary Security Domain (lock SSD) to provide a cascade locking process by which one or more of the security domains in the security hierarchy are reversibly locked when the lock SSD is reversibly locked,
- a method comprising reversibly locking the lock SSD causing one or more of the security domains in the security hierarchy to be reversibly locked.
A Digital Payment Device (DPD) comprising a Digital Transaction Processing Unit (DTPU), the DTPU hosting one or more transaction applications for digitally transacting with a Digital Transaction Device (DTD), the DTPU comprising a security hierarchy having one or more security domains, each security domain hosting at least one of the one or more transaction applications, the one or more transaction applications comprising at least one of:
- a transaction application for transacting in contact digital transactions,
- a transaction application for transacting in contactless digital transactions, or
- a transaction application for transacting in both contactless and contact digital transactions
- wherein each security domain comprises a reversable locking process by which, when the security domain is reversibly locked, the one or more transaction applications hosted by the security domain are reversibly locked so as to be inoperable during a digital transaction and cannot be directly selected by a DTD,
- wherein the security hierarchy further comprises lock Supplementary Security Domain (lock SSD) to provide a cascade locking process by which one or more of the security domains in the security hierarchy are reversibly locked when the lock SSD is reversibly locked.
