SecuKEY™ Key Management
Cryptographic Key Management Technology for light weight devices
SecuKEY™ is a patented key management technology specifically designed for light weight devices such as contactless cards, smart cards, NFC Secure Elements, RFID tags, passports and ID tokens.
Unique Keys for all devices
Many key management systems handle large numbers of devices by using diversified keys. Diversified keys are generated by using an algorithm that requires some known information (such as the device ID) and a master key. SecuKEY supports truly unique keys for each device, separating the device identity from its authentication credentials. This separation increases security and simplifies the integration of devices into systems, as well as the migration of devices.
No Backend Database Required
SecuKEY key management does not require a backend database to store the device keys and data. SecuKEY key management uses a patented way of securing the device keys called a Card Credential to store the device keys right on the device. At the time the keys are needed for decryption or authentication, the device passes the Card Credential to the counter party. If the counter party is authorized, it can retrieve the key from the Card Credential, authenticate the device, and decrypt any information it requires all without having to retrieve a back end database to retrieve the keys.
The keys used to encrypt and verify the device keys and data stored are independent from the authentication and encryption methods supported on the device itself. This allows the SecuKEY system to implement aggressive key rotation schedules on both the master keys and the device keys. Since the device keys are stored in the Card Credential on the device itself, they can be changed at any time. There is no need to update the readers before changing the device keys. Readers need only master keys, and these can be rotated on their own schedule. This makes the system suitable to large and dispersed system such as ID, transport and ticketing.
