Describe the greatest weakness from the point of view of web security of: A) One-time random pads B) General symmetric encryption algorithms that work in linear time in the length of the message C) RSA

Solution

1) One-time random pads technique is the an encrption technique wherein private key gets generated once randomly and using this receiver decrypts the message and as this is just one time generated and randomly there is no way to identify the sequence by series of messgaes.The weakness here is iit is very if pass over a secure channel but its not the case everytime with web and once this secret key gets revelead message can be easily decrypted.

2) General symmetric encryption algorithms that work in linear time in the length of the message , this technique is usually very secure as it requires both private and public key. but in order to get completly secure method over internet usually symmentric and asymmetric algorithms are used.

3) RSA its and asymmetric technique of encryption and one of the weakness would be that if the RSA key is long then fine but if short like 512 bits or something then it gets easliy breaken.
