说明：  This paper analyzes the cryptography scheme of the Trust Platform Model(TPM). The focus of the discussion would be the comparison of elliptic curve cryptography and the nowadays widely used 2048-bit RSA in evaluating which would be better suited to be used on TPM. A TPM implementation scheme based on ECC is proposed, which includes encryption and decryption schemes, signature and verification scheme, key agreement scheme. Corresponding examples of TPM commands would also be given.

说明：  基于BP算法的LDPC译码程序，采用vhdl语言，bp算法(BP algorithm based on LDPC decoding program using vhdl language, bp algorithm)
