We introduce the notation of organizational signature. This is a new variant of digital signature, which allows the organization to obtain the signature of any employee not as an individual but through his affiliation. Due to this signature, an organization, e. g. company, can create different signatures related to each position. Elliptic curves discrete logarithm problem (ECDLP) has a low computational cost and small key size, comparing with the factorization problem of RSA. In this paper, we introduce the notion of organizational signature schemes; show a construction of organizational signature schemes based on Elliptic Curve Cryptography (ECC) in the standard model.
