Abstract
Based on the demand of developing a data encryption technique for the optical storage media, the present invention discloses a cryptography for data encryption based on a design of specific hardware conditions, so as to achieve the security requirements for the encrypted digital data stored in the optical storage media and the design requirements for the security issues on the optical storage media for software vendors in the current market.
Claims5
A data processing method for an optical storage media, comprising:
- (a) reading a record of data from said optical storage media and recording said data on a system memory unit;
- (b) repeatedly reading said same record of data and recording said data on said system memory unit;
- and
- (c) performing a comparison operation on said data recorded in said step (b) and said data recorded in said step (a) to generate a set of code pairs containing at least two codes, among which two codes are used as two encryption/decryption keys in a data encryption/decryption operation.
