Reprogrammable secure software in an embedded processor |
摘要 |
Methods and an apparatus for storing information in a processing device with flexible security are disclosed. In one embodiment, a method stores information within the processing device. The method receives a download via a first input path which includes a first breakable link and stores the download within the processing device. At some point, a key is also stored within the processing device. A ciphertext download is received via a second input path which includes a second breakable link. The ciphertext download is decrypted utilizing the key and the resulting plaintext download is stored within the processing device. |
