Public key cryptographic algorithm SM2 based on elliptic curves (SM2 algorithm for abbreviation) was firstly issued in December 2010, had become the Chinese commercial cryptographic standard (GMT 0003—2012) in 2012, and had become the Chinese national cryptographic standard (GBT 32918—2016) in 2016. This paper briefly describe the development background of SM2 algorithm，describe SM2 algorithm in details，introduce the researches on its security, and evaluate its implementation efficiencies. All the researches on SM2 algorithm so far indicate that the provable securities of SM2 algorithm reach the supreme levels of public key cryptographic algorithms securities, and its implementation efficiencies are equivalent to or slightly superior to those similar elliptic curve cryptographic algorithms in some international standards.

The cryptographic hash functions play an important role in modern cryptography. They are used to compress messages of arbitrary length to fixed length hash values. The most common cryptographic applications of hash functions are with digital signature and for data integrity. SM3 cryptographic hash algorithm is issued as the industry standard in 2012. In 2016, it was published as national standard. It takes a 512bit message as input and outputs a 256bit hash value. This paper summarizes the design, properties, software and hardware implementations and cryptanalysis of SM3 cryptographic hash algorithm. Furthermore, we compare SM3 with other hash standards.

SM4 Algorithm, short for SM4 Block Cipher Algorithm, was published in 2006 to promote the application of WAPI. It became a cryptography industrial standard (GMT 0002—2012) in March 2012 and a national standard (GBT 32907—2016) in August 2016. This paper describes SM4s calculating process, structural features and cryptographic properties. Furthermore, we introduce some latest researches on SM4s security and compare SM4s security with several international block cipher standards such as AES, HIGHT and MISTY1.

SM9 identitybased cryptographic algorithm is an identitybased cryptosystem with bilinear pairings. In such a system the user s private key and public key may be extracted from user s identity and key generation centers parameters. The most common cryptographic uses of SM9 are with digital signature, data encryption, key exchange protocol and key encapsulation mechanism etc. The application and management of SM9 will not require digital certificate, certificate base, and key base. The key length of the SM9 cipher algorithm is 256b. SM9 cryptographic algorithm was issued as the cryptography standard in 2015. This paper will summarize the design, algorithm, software and hardware implementation and cryptanalysis of SM9 cryptographic algorithm. We also give some concrete examples in appendix.

In the past few years, the prosperity of the smart device market has developed in a skyrocketing pace due to the rapid development of technology, productivity, as well as the fast expanding scale of IoT (Internet of things). IoT is not only an important part in cyberspace, but also a critical point to promote the development of intelligent technology .However, the security issue of IoT device cant be ignored. Recently, there have been several campaigns made by attackers who managed to use Botnet made by IoT devices, resulted from users ignorance of security and the potential security risks of the device itself. This article is based on the DDoS(distributed denial of service) attacks against East Coast of US DNS infrastructure, aiming at getting readers attention to IoT security. Many IoT devices have security risks which could be exploited by malicious code, therefore, how to use them properly with our privacy and security secure is one of our current priorities we should care about.
