Hyper elliptical curve cryptography is the prominent public key encrypto systemswith practical approach to high level of security and shorter bit size of encryption.Public key encryption is a reliable cryptographic method for mobile adhoc networks.Still, some shortcomings of key management deter the reputation of its utilization inthe real-time environment. One major disadvantage in the crucial necessity ofelucidation is the key escrow problem. For secure group-based data transmission inthe distributed environment, a secret key has to be shared among the users for thesecured data transmission. For establishing efficient key distribution andmanagement, a novel dynamic group secret key management is introduced. In thispaper, we propose a signcryption based hyper elliptic curve cryptography frameworkfor key escrow. Here the model of scheme is to divide a large group into severalsubgroups, each maintaining its subgroup secret keys to control the subgroup andmanaging many subgroups using Key Escrow Based Hyper Elliptic CurveCryptography management algorithm. In the paper, a new methodology forcollaborative key management using signcryption is implemented. The environmentfor mobile networks with the proposed algorithm named signcryption based KeyEscrow HECC for Signcryption (KEHECCS) with a comparison of the conventionalalgorithms prevailing for MANETs is simulated. Compared to the existingapproaches, KEHECCS demonstrates advanced key distribution features with betterthroughput efficiency without compromising on communication overhead and storagecost.
