47096 对于大多数的 LDPC 码，计算环长为 g、g+2、g+4 的环数需要的时间仅为数秒。 For most of the LDPC codes, the calculation for numbers of cycle-length g、g+2、g+4 was only several seconds.
47097 如何有效保护无线体域网（WBAN）中数据共享时的数据安全是一个亟待解决的关键问题。 How to effectively protect the security of data sharing in WBAN was a key problem to be solved urgently.
47098 传统的 CP-ABE机制具有“一对多”的数据安全通信功能，适用于 WBAN 中的访问控制，但运算复杂度高且不支持属性撤销。 Thetraditional CP-ABE mechanism had a one to many data security communication function which was suitable for accesscontrol in WBAN, but it had high computational complexity and did not support attribute revocation.
47099 充分考虑 WBAN 节点资源的有限性和用户属性的动态性，提出一种在标准模型下 CPA 安全、支持属性撤销、加密和解密安全外包计算的 CP-ABE 方案。 Fully considering oflimitations on computation and storage of sensor nodes and dynamic user attribute in WBAN, a CP-ABE scheme wasproposed which was provably secure against CPA under the standard model and supported attributes revocation, out-sourced encryption and decryption.
47100 与已有的方案相比，提出的方案在保证安全性的同时，终端的运算负担大为减少，且可以实时、细粒度地撤销用户属性。 Compared with the proposed schemes, the computation burden on senor nodes isgreatly reduced and the user’s attribution can be revoked immediately and fine grained while meeting the demand of itssecurity in the proposed scheme.
47101 全同态加密在云计算的数据和隐私安全领域有重要应用，但现有全同态加密体制普遍存在密钥、密文尺寸偏大的弊端，严重制约其实用性。 The fully homomorphic encryption has important applications in the area of data security and privacy securityof cloud computing, but the size of secret keys and ciphertext in most of current homomorphic encryption schemes weretoo large, which restricted its practical.
47102 为此，以环上容错学习问题为基础，提出环上重编码体制与基于属性加密体制，并与全同态加密体制结合，构造基于属性的全同态加密体制， To improve these drawbacks, a recoding scheme and a attribute-based encryptionscheme based on learning with errors problem over rings were provided, then a attribute-based fully homomorphic en-cryption was constructed.
47103 该体制无需公钥证书，可实现对加密数据细粒度访问控制， The new scheme overcame the above mentioned drawbacks, because it did’t need public keycertificate, meanwhile, it can achieve the fine-grained access control to the ciphertext.
47104 与已有同类成果相比，大大缩短了密钥与密文尺寸。 Compared with similar results,proposed method decreases the size of keys and ciphertext greatly.
47105 针对多输入单输出（MISO, multiple input single output）通信系统的 STBC-OFDM 信号盲识别问题，提出基于 OFDM 块的改进 Kolmogorov-Smirnov (K-S)检测方法。 Aiming at the problem that existed blind classification of STBC-OFDM in multiple input single output (MISO)communication system, an efficient method for blind classification of space-time block coded orthogonal frequency-divisionmultiplexing (STBC-OFDM) signals based on modified Kolmogorov-Smirnov (K-S) test was proposed, when a single re-ceiver antenna was employed at the receiver.
