Image　encryption　technology　plays　an　important　role　in　today’s　multimedia　applications　and　Internet　information　security　transmission.　However,　most　image　encryption　algorithms　still　have　problems,　for　example,　cipher　images　occupied　high　bandwidth　during　transmission,　image　encryption　speed　is　slow,　image　encryption　algorithms　are　not　associated　with　plain　image,　and　there　is　no　complete　ciphertext　feedback　mechanism.　These　prob-lems　all　affect　the　security　and　easy　use　of　image　encryption　algorithms.　In　order　to　solve　the　above　problems,　the　compressive　sensing　technology　and　chaotic　system　were　studied,　and　a　new　image　encryption　algorithm　based　on　double　chaotic　system　and　compressive　sensing　with　plaintext　association　was　proposed.　The　plaintext　image　association　key　was　used　to　associate　the　plain　image　hash　value　with　the　Logistic　chaotic　system　parameters.　Discrete　wavelet　transform,　was　used　to　sparse　the　plain　image.　Then　the　random　measurement　matrix　was　generated　by　the　Logistic　chaos　system,　and　the　image　was　encrypted　once　by　combining　the　compressive　sensing　technique　and　the　random　measurement　matrix　to　obtain　the　intermediate　image.　The　intermediate　image　was　hashed　again,　and　the　Rucklidge　chaos　system　initial　value　was　associated　with　the　plain　image　hash　value　together.　The　Rucklidge　chaotic　system　and　encryption　algorithm　were　used　to　control　the　intermediate　image　for　secondary　encryption　and　accord-ingly　obtain　the　cipher　image.　The　encryption　algorithm　was　a　new　plaintext　correlation　encryption　algorithm,　which　used　the　image’s　own　pixel　value　to　control　the　scrambling　of　the　intermediate　image.　It　also　enhanced　the　plaintext　association　and　established　a　ciphertext　feedback　mechanism.　Simulation　results　and　performance　analysis　show　that　the　algorithm　has　good　encryption　performance.　The　encrypted　image　can　be　compressed　according　to　the　compres-sion　ratio,　effectively　reducing　the　size　of　the　cipher　image.　Moreover,　it　is　resistant　to　common　attacks　such　as　known　plaintext　attack,　selective　plaintext　attack　and　differential　attack,　which　is　better　than　other　common　image　encryption　algorithms.　©　2022,　Beijing　Xintong　Media　Co.,　Ltd..　All　rights　reserved.
