WebJan 1, 2001 · In this paper, we describe some variations and generalizations of the Beimel-Chor scheme, including broadcast encryption schemes as well as interactive key distribution schemes. Our constructions use the key predistribution scheme of Blundo et al, which is a generalization of the Blom scheme. We obtain families of schemes in which … WebCurrently the library contains the following algorithms: algorithm type name authenticated encryption schemes GCM, CCM, EAX high speed stream ciphers Panama, Sosemanuk, Salsa20, XSalsa20 AES and AES candidates AES (Rijndael), RC6, MARS, Twofish, Serpent, CAST-256 IDEA, Triple-DES (DES-EDE2 and DES-EDE3), other block ciphers …

Blom's scheme is a form of threshold secret sharing. Blom's scheme is currently used by the HDCP (Version 1.x only) copy protection scheme to generate shared keys for high-definition content sources and receivers, such as HD DVD players and high-definition televisions .
