identity sign
1.1. Three e? cient signcryption schemes are proposed, including of a certificate-basedsigncryption scheme, an identity-based signcryption scheme, and a self-certified sign-cryption scheme.
4.Moreover, using CRD domain of CD23L peptide searching protein database, showed that 70% identity to the mouse unnamed protein, 39% to DC-SIGNR, 38% to DC-SIGN and 37% to CD23. CD23L, DC-SIGNR, DC-SIGN and CD23 all belong to type II integral membrane protein, and display similar protein domain organization.
