Cloud-aided　scalable　revocable　identity-based　encryption　with　ciphertext　update　(CA-RIBE-CU),　first　introduced　by　Wang　et　al.　in　2017　and　the　first　lattice-based　instantiation　constructed　by　Zhang　et　al.　in　2021,　offer　significant　advantages　over　previous　identity　revocation　mechanisms　when　considering　the　scenario　of　secure　data　sharing　in　the　cloud　setting.　In　this　primitive,　the　receiver　can　utilize　the　short-term　decryption　keys　to　decrypt　all　encrypted　data　sent　to　him　or　her,　meanwhile,　the　ciphertexts　stored　in　the　cloud　will　update　to　new　ones　with　the　aided　of　an　untrusted　cloud　service　provider　(CSP)　and　without　any　interaction　with　the　data　owners,　and　thus,　the　revoked　receivers　cannot　access　to　both　previously　and　subsequently　shared　data,　that　is,　to　achieve　both　identity　revocation　and　ciphertext　update　simultaneously　for　IBE.　In　this　paper,　inspired　by　the　first　quantum　resistant　construction　of　CA-RIBE-CU　by　Zhang　et　al.　in　FCS　2021,　we　propose　a　new　lattice-based　CA-RIBE-CU　scheme　in　the　random　oracle　model　(ROM).　We　also　adopt　the　two　interesting　tools　＂hybrid　ciphertexts＂　and　＂hybrid　short-term　decryption　keys＂　proposed　by　Zhang　et　al.　to　enable　constant　ciphertexts　and　simplified　ciphertexts　update.　Differently,　instead　of　using　a　super-lattice　to　issue　the　long-term　private　keys　and　the　time　update　keys,　our　new　construction　is　based　on　the　main　technique　for　lattice　basis　delegation　without　dimension　increase,　which　benefits　the　new　CA-RIBE-CU　scheme　with　much　shorter　items　in　almost　all　keys　and　final　ciphertexts,　thus　enriching　the　research　of　lattice-based　revocable　IBE.
