Over the years, numerous cryptographic algorithms have been developed and used in many different protocols and functions. Cryptography is by no means static. Steady advances in computing and in the science of cryptanalysis have made it necessary to adopt newer, stronger algorithms and larger key sizes. Older algorithms are supported in current products to ensure backward compatibility and interoperability. However, some older algorithms and key sizes no longer provide adequate protection from modern threats and should be replaced. This paper summarizes the security of cryptographic algorithms and parameters, gives concrete recommendations regarding which cryptography should be used and which cryptography should be replaced, and describes alternatives and mitigations.

When target devices are transmitting a reactive jammer jams the wireless channel; Reactive jamming is harder to track and compensate against the constant jamming methods. Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum DSSS) have been widely used against Jamming attacks. If high power transmitter or frequency channel is jammed then both these method will fail. We use broad band and high power reactive jammer to avoid jamming attacks. In this proposed method we use bit trickle method to avoid jamming. Bit Trickle is a method which is used to find attackers when using broadband communication between transmitter and receiver. Users having secret key to access the data from anti jammer. Once the security key is correct then only the transmission occurs.
