One Time Pad Recall OTP. Assume that the RNG stopped working in the middle of the key generation and generated k1, a key which length is half the length of message m. Answer the following questions. (a) If we use k1 two times (i. e. use k1||k1 as the key, where || denotes concatenation) to encrypt m using the OTP scheme, will the resulting ciphertext be secure

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
