security - Data encryption algorithm which decrypts the data only once but need a different key to decrypt it again -

is there encryption algorithm in encrypted data/file can decrypted key once, should re-encrypt file different key needed decrypt same file again. well, not algorithm per se -- once have key, data decrypted. there techniques that, , typically pivot on 1 of following: software obfuscation (you can google keywords such "software protection"), or hardware attack countermeasures (look "trusted execution environment" example), or both @ same time. this example pretty happens when watch netflix movie on pc connected hdmi tv: @ simplified level, happens movie encrypted drm key k1, gets decrypted k1 on pc, , re-encrypted new hdcp key k2 on way out tv (then tv decrypt same hdcp key k2). same story miracast , other similar protocols.
