The method involves providing a device with an encryption key stored in memory, providing an external entity with identity data for transmission to the device, applying a one way function to the encryption key and the identity data to generate a variant key, authenticating communications between the device and the external entity with the variant key and limiting the number of times the encryption key is retrieved from the first memory to a pre-determined threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of encrypted communication with limited number of stored encryption key retrievals","description":"A method of encrypted communication between entities in a manner that frustrates side channel attacks attempting to determine an encryption key.
