Authenticated Encryption Schemes with Message Linkage for Threshold Signatures
Chi-Hsiung Huang, Chia‐Yin Lee, Chu‐Hsing Lin, Chin‐Chen Chang, Kuo-Lun Chen · 2005
Based on the factorization problem, a modified (t, n) threshold group-oriented scheme with message recovery is proposed. In the proposed scheme, any combination of more than t members of the group can cooperate to generate the modified group secret key. By using the proposed scheme, the transmission of the signature is secure. Besides, the message linkage blocks which are removed by an eavesdropper can be detected.
