Encryption in the cloud with customer controlled keys
View Patent ↗A system and method for encryption in a cloud computing platform with customer controlled keys is disclosed. A cloud-based encryption key is uploaded from a customer computing platform to a key store of the cloud computing platform, based on a customer-based encryption key. The cloud-based encryption key and customer-based encryption key is able to encrypt or decrypt customer data used by an application server running on the cloud computing platform. Next, the cloud-based encryption key is unlocked from the key store, and then stored in a secure store of a main memory associated with the customer computing platform. Then, according to encryption or decryption mechanism, the unlocked cloud-based encryption key is accessed to encrypt or decrypt customer data stored on a database of the main memory and used by the application server.
1. A method for encryption in a cloud computing platform with customer controlled keys, the method comprising:
uploading, from a customer computing platform to a key store of the cloud computing platform, a cloud-based encryption key based on a customer-based encryption key, the cloud-based encryption key and customer-based encryption key being able to encrypt or decrypt customer data used by an application server running on the cloud computing platform;
retrieving the customer-based encryption key stored on the customer computing platform;
unlocking, by one or more processors executing a key unlocking mechanism using the customer-based encryption key, the cloud-based encryption key from the key store;
storing, by one or more processors, the unlocked cloud-based encryption key in a secure store of a main memory associated with the customer computing platform; and
accessing, by one or more processors executing an encryption or decryption mechanism, the unlocked cloud-based encryption key to encrypt or decrypt customer data stored on a database of the main memory and used by the application server.
2. The method in accordance with claim 1 , wherein the unlocking the cloud-based encryption key further includes:
unlocking the cloud-based encryption key from the key store using the customer-based encryption key.
3. The method in accordance with claim 1 , wherein the accessing the unlocked cloud-based encryption key to encrypt or decrypt customer data further includes:
determining a relationship of the customer data with the cloud-based encryption key.
4. The method in accordance with claim 3 , wherein the accessing the unlocked cloud-based encryption key to encrypt or decrypt customer data further includes:
accessing the unlocked cloud-based encryption key according to the relationship.
5. A computer program product comprising a non-transitory machine-readable medium storing instructions that, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
uploading, from a customer computing platform to a key store of the cloud computing platform, a cloud-based encryption key based on a customer-based encryption key, the cloud-based encryption key and customer-based encryption key being able to encrypt or decrypt customer data used by an application server running on the cloud computing platform;
retrieving the customer-based encryption key stored on the customer computer platform;
unlocking, according to a key unlocking mechanism using the customer-based encryption key, the cloud-based encryption key from the key store;
storing the unlocked cloud-based encryption key in a secure store of a main memory associated with the customer computing platform; and
accessing, according to an encryption or decryption mechanism, the unlocked cloud-based encryption key to encrypt or decrypt customer data stored on a database of the main memory and used by the application server.
6. A system comprising:
at least one programmable processor; and
a machine-readable medium storing instructions that, when executed by the at least one processor, cause the at least one programmable processor to perform operations comprising:
uploading, from a customer computing platform to a key store of the cloud computing platform, a cloud-based encryption key based on a customer-based encryption key, the cloud-based encryption key and customer-based encryption key being able to encrypt or decrypt customer data used by an application server running on the cloud computing platform;
retrieving the customer-based encryption key stored on the customer computing platform;
unlocking, according to a key unlocking mechanism using the customer-based encryption key, the cloud-based encryption key from the key store;
storing the unlocked cloud-based encryption key in a secure store of a main memory associated with the customer computing platform; and
accessing, according to an encryption or decryption mechanism, the unlocked cloud-based encryption key to encrypt or decrypt customer data stored on a database of the main memory and used by the application server.
7. The system in accordance with claim 6 , wherein the unlocking the cloud-based encryption key further includes:
unlocking the cloud-based encryption key from the key store using the customer-based encryption key.
8. The system in accordance with claim 6 , wherein the accessing the unlocked cloud-based encryption key to encrypt or decrypt customer data further includes:
determining a relationship of the customer data with the cloud-based encryption key.
9. The system in accordance with claim 8 , wherein the accessing the unlocked cloud-based encryption key to encrypt or decrypt customer data further includes:
accessing the unlocked cloud-based encryption key according to the relationship.
