Question

describe the mechanisms required for wireless sensor node​

Answer 1

$\sf{Answer}$

In random key pre- distribution, a random set of keys or key-related information are/is assigned to each sensor node. Thus, in the key set-up phase, each node can detect or compute the usual keys it shares with its neighbors. The common keys are used as shared secret session keys to ensure node-to-node secrecy.

Answer 2

Answer:

In a WSN, the issue of confidentiality should address the following requirements [30, 35]: (i) a sensor node should not allow its readings to be accessed by its neighbors unless they are authorized to do so, (ii) key distribution mechanism should be extremely robust, (iii) public information such as sensor identities, ...
