Key updating for leakage resiliency with application to Shannon security OTP and AES modes of operation

Side channel analysis (SCA) represents frequently occurred and major type of attack against implementation of any cryptographic protocols. SCA has ability to directly attack on small part of the key and aggregate this information over different encryption. We can prevent SCA attack by changing secret key at every run. Leakage resilient cryptography is used to design cryptographic protocol that remains secure in the presence of arbitrary information about the secret key. In this paper we proposed a framework which protects the current cryptographic standard and also evaluate SCA-security. We send the secure data using any cryptographic primitive (AES) running in a mode of operation. We can also choose Shannon's Security mode to send data using cryptographic primitive (One Time Padding). We are using switch to ensure that stateless key-updation using alternative or random algorithm choice such as AES or OTP will be used, instead of relying on one single technique.
