Encryption Algorithm simple description : DES is a block cipher algorithm, his 64 for a pair of data encryption Encryption algorithm principle :The password system may divide into 2 big kinds from the principle, namely single key password system and double key password system.

加密算法的简单描述：DES是一种分组加密算法，他以64位为分组对数据加密。加密算法的原理：密码体制从原理上可分为2大类，即单钥密码体制和双钥密码体制。

This makes the definition even not equivalent to the indistinguishability, which contradicts with what has been widely acknowledged.(3) One-time and multi-message hybrid encryptions is separated, especially the security definitions for them. For the most direct paradigm of hybrid encryption PKE+SKE, the IND-CCA_I security when it is a one-time one and the IND-CCA5 security when it is a multi-message one are proved respectively. For both of them, the necessity of the security requirement for PKE and SKE is discussed.(4) For the KEM+SKE multi-message hybrid paradigm, i.e.

Active attack cryptanalysis based and fully scalable FGS encryption algorithm Aimed to the weakness of the current selective encryption algorithms in the sense of cryptanalysis, we design a active spacial—temporal correlation attack scheme and propose a both encryption strategies on base-layer and enhancement-layer. Not only the general FGS stream encryption is dealt with but also the case of FGST (fine granularity sealable temporal) is also well addressed.

BACE algorithm has the desired property that does not reduce the encoding efficiency of the CABAC entropy encoder compared to the CIME algorithm for CAVLC entropy encoder. Both CIME and BACE algorithms can adapt to the content security level by choose the amount and different key parts of the video stream to be encrypted, the theoretical and experimental results show that both these algorithms can effectively encrypt the video content. Due to the ability of encrypting the video content without violating the syntax, the BIME and BACE algorithms can be employed used for many advanced H.264/AVC coding options without first decrypting the video stream, like Data Partition and UnEqualized Protection for the enhancement of transmission robustness, and the scalable coding in order to match the different channel capacity.

The invention discloses a digital good transaction system and the method. It mainly carries on coding process to at least one digital good in a content downloading center into a coded digital good, and the coded digital good will be transmitted to at least one content downloading station with real memory transmission path, when the consumer selects a digital good, the user can uses a content downloading card into a content downloading station, uses a reality transmission path to store the digital good to be purchased, and uses a network transmission wire to connect the content downloading center, the center incriminates the card number in order to generate a card number decoding data, and download the decoding data into a content downloading card, when the consumer want toe buy a digital good, the content can be downloaded into a content card reader, and the reader incriminate the card number to reduces the decoded data and the digital good, in order to generate the digital good which can be read and used.
