SM9 (classification)
S9, SB8, SM9 are disability swimming classifications used for categorizing swimmers based on their level of disability. Swimmers in this class generally have severe weakness in one leg. This class includes a number of different disabilities including people with amputations and cerebral palsy. The classification is governed by the International Paralympic Committee, and competes at the Paralympic Games. Definition This classification is for swimming. In the classification title, S represents Freestyle, Backstroke and Butterfly strokes. SB means breaststroke. SM means individual medley. Jane Buckley, writing for the Sporting Wheelies, describes the swimmers in this classification as having: "severe weakness in one leg only; Swimmers with very slight coordination problems; Swimmers with one limb loss. Unless there is an underlying medical condition usually all of these athletes will start out of the water." Swimming classifications are on a gradient, with one being the most se ...

SM9 (cryptography Standard)
SM9 is a Chinese national cryptography standard for Identity Based Cryptography issued by the Chinese State Cryptographic Authority in March 2016.  It is represented by the Chinese National Cryptography Standard ( Guomi), GM/T 0044-2016 SM9. The standard contains the following components: * (GM/T 0044.1) The Identity-Based Asymmetric Cryptography Algorithm * (GM/T 0044.2) The Identity-Based Digital Signature Algorithm which allows one entity to digitally sign a message which can be verified by another entity. * (GM/T 0044.3) The Identity-Based Key Establishment and Key Wrapping * (GM/T 0044.4) The Identity Based Public-Key Encryption Key Encapsulation Algorithm which allows one entity to securely send a symmetric key to another entity.  Identity Based Cryptography Identity Based Cryptography is a type of public key cryptography that uses a widely known representation of an entity's identity (name, email address, phone number etc.) as the entity's public key. This eliminates t ...
