Abstract In sensor networks, it is a challenge to ensure the security of data exchange
between packet switching nodes holding different private keys. In order to solve this
problem, the present study proposes a scheme called multi-conditional proxy broadcast reencryption (MC-PBRE). The scheme consists of the following roles: the source node,
proxy server, and the target node. If the condition is met, the proxy can convert the
encrypted data of the source node into data that the target node can directly decrypt. It
allows the proxy server to convert the ciphertext of the source node to a new ciphertext of
the… More >
