In many situations, the technique to hide a secret is needed. One might need to hide a password, an encryption Key, a secret recipe, and etc. Information can be secured with encryption, but the need to secure the secret key used for such encryption is important too. Consider, we encrypt our important files with one secret key and if that secret key is lost then all the important files will be inaccessible. Thus, secure and efficient key management mechanisms are required. One of them is secret sharing scheme (SSS) that allows to split the secret into several shares which will get distributed to all the participants. The secret can be recovered once these parties collaborate in some way. This survey paper will study these schemes and explain the need for the secret sharing and their security. Across the years, various schemes have been presented. This paper will review some of them varying from trivial schemes to threshold based ones.
