Abstract
Various techniques provide systems and methods for facilitating data encryption/decryption and almost immediate erasure of associated information. In one example, a method includes receiving first data in a first memory. The method further includes receiving a first key in a second memory. The method further includes generating, by a logic circuit, second data based on the first data and the first key. The method further includes providing the second data for transmission. The method further includes erasing the first data and/or the first key in one-half clock cycle of generating the second data. Related methods and devices are also provided.
Claims20
A method comprising:
- receiving (1805) first data in a first memory (1505);
- receiving (1810) a first key in a second memory (1510);
- generating (1815), by a logic circuit (1515), second data based on the first data and the first key;
- providing (1820) the second data for transmission;
- and
- erasing (1825) the first key in one-half clock cycle of generating the second data.
A device comprising:
- a logic circuit (1515) configured to generate (1815) second data based on first data and a first key;
- a first memory (1505) configured to receive (1805) the first data;
- and
- a second memory (1510) configured to:
- receive (1810) the first key;
- and
- receive values to overwrite (1825) the first key in one-half clock cycle of generation of the second data.
