The device has a first memory, an encryption key stored in the first memory and a one-way function for application to the encryption key. During use, the encryption key is retrieved from the first memory prior to application to the one-way function and the device is configured to limit the number of times the encryption key is allowed to be retrieved from the non-volatile 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":"Encrypted communication device with limited number of encryption key retrievals from memory","description":"A device for encrypted communication with external entities is configured to frustrate side channel attacks attempting to determine an encryption key.
