Abstract
An electronic system includes a control system configured to transmit an encrypted bit stream, an electronic device configured to extract a security key by decrypting the encrypted bit stream and to compare the security key with a check security key to extract programming data for a programming operation by decrypting the encrypted bit stream when the security key and the check security key are the same as each other.
Claims19
An electronic system comprising:
- a control system configured to transmit an encrypted bit stream;
- an electronic device configured to extract a security key by decrypting the encrypted bit stream and to compare the security key with a check security key to extract programming data for a programming operation when the security key and the check security key are the same,
- wherein the security key includes a first security key and a second security key,
- wherein the check security key includes a first check security key and a second security key, and
- wherein the electronic device includes:
- a pass signal generation circuit configured to compare the first security key and the first check security key and compare the second security key and the second check security key to generate a pass signal;
- and
- a programming data extraction circuit configured to decrypt the encrypted bit stream based on the pass signal to extract the programming data.
